SUMMARY ISO-10303 (STEP) has begun to develop International Standardization as standard for the exchange of product model data . But we cannot say that the functions for design change and preparation for production are fully developed. For the purpose of extracting its problems, we start to research the mechanical manufacturing process, and we have arrived Integrated Application Activity Model (I-AAM) by functional analysis for mechanical manufacturing product system from design to manufacturing process. We got the above ideas as ISO/SC4/N-numbered document and reported at ISOZSC4 meeting. Especially by considering the results of I-AAM and Japanese industry needs, we have started to develop the Assembly Model for Design and Product process, and Machining Process Data Model for manufacturing process. We reported those results at three times TC184/SC4 meeting in this year, and those documents have registered as SC4 N-Numbered document.
l We will plan more detail investigations and create precise data model, and we will set our projects results as New Work Item proposal by next year.

Martin Hardwick gave the status for ISO 14649 - Shop Floor NC Controllers (TC184/SC4/WG7). • Slides available on request • Univ of Aachen = Project lead for development of the Part 11 ARM • ISO 14649 is replacing ISO 6983 • Part 11 - Many CD ballot comment changes required • U S. Position that Part 11 should be resubmitted for a second CD ballot • Committee voted 5-4 that Part 11 should be submitted for DIS ballot • Needs to be integrated/harmonized with STEP 10303 • Germany, Japan, Switzerland, and the U.S. are the strongest participants Len Slovensky gave an AP224 Summary (and AP214/AP224 Harmonization) • Slides available on request • AP214 and AP224 Teams have agreed upon Feature and Tolerance harmonization • Pointed out differences between AP214 and AP224 • Noted that AP219 (Dimensional Inspection) is moving toward feature harmonization with AP214& AP224 • Noted that AP213 (NC Process Plans for Machined Parts) was being revived • Discussed new additions for the second edition of AP224 (Assemblies & 5-axis features) 172 Takeshi Kishinami presented a Proposed AAM for Mechanical Design and Manufacturing • Slides available on request • Hardcopies of proposal were handed out • Scope (In and Out) discussed • Discussion of relationship of AP213, AP214, AP219, AP224, IS014649, and the AAM followed • Noted that AP214 appeared to handle most of what was in the model, but not NC code. • Action: (Takeshi Kishinami) - Research what TC29 WG34 ISO 13399 (Cutting and Turning Tools) is doing and its relation to this activity • Possibly some relation to MANDATE and the use of PUB • Action: (Takeshi Kishinami) - needs to research process planning in AP213 and AP214. Also research PLIB’s relationship to the AAM Question: What next? • Translate to Express • Define interface between Operational Processes and Cutting Tools • It was noted that AP214 Process Plans could be complementary • Question - Where would we use this AP? A follow-up meeting was proposed before the Melbourne Meeting to discuss where standards fit into the AAM and who is doing what. Suggested locations for this meeting: • Tokyo, Singapore, Hawaii, Melbourne • Most felt that it should be held “on the way ” or “at/before” the ISO Meetings • The meeting should be for two days • Emails to determine meeting place and dates. 173 1.

Features in panel are speciality to AP214 - Issues detected by developing Recommended practices for Cax Implementor Forum by ProSTEP/PDES and by investigations for requirements on AP224.2 by Len Slovensky Issues/Agreements:: Issue Agreement Profiles, paths, transition_features, replicate_feature => AP224.2:releasing constraints (upward compatible AP224: mandatory attributes change for the issue optional vs. required attributes) AP214: optional attributes, and differences in STRING values Transistionfeature, replicatefeature => AP214 change rules at subtypes, AP224 rules local use strings from AP224 AP214: rules at parent mapping through OR cases for face 1 and face 2 (on string values) Replicate_feature: => Open! AP214 has new entity pattern feature Compound_features: AP214: Parent feature: Compound Feature in: solid 187 Issue Agreement AP224: Parent feature: Machining feature Thread: => AP214: no subtype threadoccurrence AP214: additional attribute, external_thread_definition shape_aspect. name = „thread_occurence" AP224: external_feature_definition change mapping thread_feature.thread_definition to IDENTICAL MAPPING in included feature case -parameters to threadoccurence at shapeaspect corresponding to AP224 - appliedarea (subtype of shape_aspect) change externally_defined_thread to externally_defined_feature_definition (char_object.description = .thread"} AP214: attribute english_or_metric in the ARM! => AP224.2: change mapping applied area to thread to applied area to instanced feature Hole: => AP214: proposal to use tapered hole instead of AP214: hole with chamfer chamfer in AP214 in ARM, AIM accordingly AP224: Countersunkhole and counterbore hole final decision on AP214 ARM change in New Orleans recommendation for implementor forum: do not use optional chamfer, use compound mechanism with two holes: 1 round hole, 1 tapered-hole (compatible to AP224, mapping identical to future mapping where AP214 ARM will be changed) AP214 DIS issue on flat_with_taper_bottom/removal of top chamfer by Len Slovensky Different attribute values, e g. „hole bottom occurence" - => AP214: use AP224 strings ,,bottom condition occurence" Type of taper, path_feature_component_condition in => AP214: Leave as is (in description attribute) description attribute: (consistent between AP224 and AP214, but inconsistent within AP214 because normally in name attributes) List of features: => only 5 AP224 feauture types used by AP214 AP214 has 2 additional features: rib features, general feature Issues against AP214 DIS will be submitted by US / AP224.2 Team 188 SEDS issues on AP224 will be submitted by GER / AP214 Team &L± TWG11 EXPRESS m BBt : 1999/6/8(^0 13:00-15:00 : Pill Spiby, Donard Sundarson, Julian Fawller, 1 .

If new application resource model is introduced, the other APs dealing with the assemblies may use different data structures. There are many overlaps between the assembly model and the APs (AP 214, AP221, etc.) Action WG 3 chair will review N 448 Assembly model, and will examine whether AM is better. * Workshop in Melborne Meeting to distribute information to get the interest members from other countries. *NWI proposal Before Australia or France Meeting. mmm AP#mm, G.

Assembly model schema The following EXPRESS declaration begins the assembly_model_shcema and identifies the necessary references.

The products to be described by the assembly model are summarized in the followings. (1) products composed of sets of components. The products considered here are the assembled products composed of sets of the components. The whole products are called "assemblies", and the components of the lowest levels in the assemblies are called "parts". The components of the intermediate levels are called "sub-assemblies", which are composed of one or more parts and/or sub-assemblies. An assembly consists of one or more sub-assemblies and parts. (2) Product structure configuration of assembly Product structure configuration is now dealt with in ISO 10303 - 44 to describe the parts lists and the BOM (bill-of-material). Various structure configurations are given to one assembly depending on various contexts. For instance, one configuration of an assembly is considered in the design phase, and the structure configuration may be changed in the assembly process planning phase. The objective of the assembly model is to establish a model describing both the product structure configuration and the connecting associations among the components needed in the various design, analysis and manufacturing process planning phases. (3) Standard parts 235 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 031, Feb. 17, 2000) 7 The assemblies include many standard parts, such as fixing bolts, keys, and electric motors. The standard parts are basically divided into two; they are, the standard parts included in the parts catalogues discussed in ISO TC 184/SC4/WG2, and the standard parts defined by the users. The interest application fields of the assembly model are as follows. (1) Kinematic analysis of mechanical assemblies Kinematic analysis and simulation are very important application fields of the assembly model. ISO 10303-105 Kinematics supports the kinematic analysis, however, Part 105 is not sufficient to integrate the 3D-CAD systems and the kinematic analysis systems. (2) Animation of mechanical assemblies The animation of mechanical assemblies is very important for future extension of the digital-mockup technologies. (3) Assembly/disassembly process planning The assembly model will support the integration of the product design and the manufacturing preparation. The assembly process planning and the disassembly process planning are important application fields of the assembly model from the viewpoint of the integration of CAD and CAM systems. (4) Tolerance analysis and synthesis The tolerance analysis and synthesis of the complicated mechanical assembly are very important application fields of the assembly model. 4.2 Fundamental concept and assumptions (to be completed) 4J assembly model schema type definition: assemby feature schape An assembly feature shape is a selection between types of shapes of assembly features.

INTRODUCTION The objective of this attachment is to present a basic idea and examples of the product model called an assembly model, which is applicable to describe the mechanical assemblies based on the STEP framework. In particular, emphasis is given to establish a data structure to represent the peer to peer associations among the components of the assemblies. 2. CONTENTS OF ASSEMBLY MODEL 2.1 Target Product The target products to be represented by the assembly model are summarized as follows. (1) products composed of sets of components. The products considered here are the assembled products composed of sets of the components. The whole products are called "assemblies", and the components of the lowest levels in the assemblies are called "parts". The components of the intermediate levels are called "sub-assemblies", which are composed of one or more parts and/or sub-assemblies. An assembly consists of one or more sub-assemblies and parts. (2) Product structure configuration of assembly Product structure configuration is now dealt with in ISO 10303 - 44 to describe the parts lists and the BOM (bill-of-material). Various structure configurations are given to one assembly depending on various contexts. For instance, one configuration of an assembly is considered in the design phase, and the structure configuration may be changed in the assembly process planning phase. The objective of the assembly model is to establish a model describing both the product structure configuration and the connecting associations among the components needed in the various design, analysis and manufacturing process planning phases. (3) Standard parts The assemblies include many standard parts, such as fixing bolts, keys, and electric motors. The standard parts are basically divided into two; they are, the standard parts included in the parts catalogues discussed in ISO TC 184/SC4/WG2, and the standard parts defined by the users. 2.2 Interest Application Fields The interest application fields of the assembly model are as follows. (1) Kinematic analysis of mechanical assemblies 257 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 031, Feb. 17, 2000) 29 Kinematic analysis and simulation are very important application fields of the assembly model. ISO 10303-105 Kinematics supports the kinematic analysis, however, Part 105 is not sufficient to integrate the 3D-CAJD systems and the kinematic analysis systems. (2) Animation of mechanical assemblies The animation of mechanical assemblies is very important for future extension of the digital-mockup technologies. (3) Assembly/disassembly process planning The assembly model will support the integration of the product design and the manufacturing preparation. The assembly process planning and the disassembly process planning are important application fields of the assembly model from the viewpoint of the integration of CAD and CAM systems. (4) Tolerance analysis and synthesis The tolerance analysis and synthesis of the complicated mechanical assembly are very important application fields of the assembly model. 2.3 Contents of Assembly Model The contents of the assembly model are analyzed from the viewpoints of the design, the analysis and the manufacturing preparation of the mechanical products. The contents are classified into four classes. They are, (1) Information of individual parts. (2) Information of standard parts. (3) Structure configuration of assembly a) Hierarchical associations (parent-child associations) among assemblies, subassemblies and parts. b) Positions and orientations of components in a higher level component. c) Tolerance of the positions and orientations (4) Component Association a) Peer to peer associations among components. b) Relative positions and orientations of components against other components. c) Relative motions of components against other components. d) Tolerance of the relative motions, positions and orientations. e) Assembly features needed to define technological information of component associations. 258 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 0.31, Feb. 17, 2000) 30 Table 1 Contents of STEP model Information STEP Model (1), (3)-a), (3)-b) ISO 10303: Part 41 : Fundamentals of Product Description and Support.

(2) ISO 13584: Standard Parts Most of the information mentioned above can be described by the integrated generic resources and application resources defined in the Parts of the STEP (ISO 10303). Table 1 summarizes the contents of the STEP model. The information about the individual parts are represented by ISO 10303-41, 42, 43, 45, 46, 47 and 49., and the information about the standard parts may be defined by ISO 13584. As regards the assembly information (3) and (4), ISO 10303-44 Product Structure Configuration model provides a mechanism to represent (3)-a), (3)-b) and (4)-b). ISO 10303-105 Kinematics gives the mechanism to represent the relative motion between pairs of links that are a set of components fixed with each other. Therefore, the assembly model deals with the following items of the mechanical products. (4) Component Association a) Peer to peer associations among components. b) Relative positions and orientations of components against other components. c) Relative motions of components against other components. e) Assembly features needed to define technological information of component associations. The following items related to the tolerances are considered in the other Part of this Standards. 259 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 0.31, Feb. 17, 2000) 31 (3) Structure configuration of assembly c) Tolerance of the positions and orientations (4) Component Association d) Tolerance of the relative motions, positions and orientations. 260 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 031, Feb. 17, 2000) 32 3. BASIC IDEA OF ASSEMBLY MODEL 3.1 Assembly Features Figure 1 (a) shows a simple example of the mechanical assembly, which consists of two plates and a fixing bolt. In this case, the connecting associations among the components are presented in the diagram of Fig. 1 (b). In the figure (b), the rectangular blocks show the shape elements on which a pair of components are connected and/or associated. The shape elements, such as planes, holes, screws and nuts, are called “assembly feature” in the assembly model. The assembly features are the elemental entities for representing the peer to peer associations between a pair of components. For the example, two cases may be considered to represent the assembly features between the flange plate and the bolt in Fig. 1(b). CASE1: The each individual component has one assembly feature. Assembly feature 1 of flange plate = Hole + Plane Assembly feature 2 of bolt = Cylinder + Plane CASE 2: The individual faces are defined as the individual features. Assembly feature 11 of flange plate = Hole Assembly feature 12 of flange plate = Plane Assembly feature 21 of bolt = Cylinder Assembly feature 22 of bolt = Plane The definition of the assembly feature depends on the various viewpoints and the application fields, therefore, both the assembly feature definition of CASE 1 and CASE 2 should be taken into consideration in the assembly model. Figure 2 shows another example of the assembly of the automotive engines. In this case, the connecting associations include both the fixed connecting association and the movable connecting associations, as shown in Fig. 3. The types of the joints are described for the individual association between the pairs of the assembly features in Fig. 3. A spring part, an elastic component, is also included in the assembly. 261 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 031, Feb. 17, 2000) 33 Screw & Nut Screw Plane & Plane _ Hole & | Hole"^| plane) | plane Cylinder plane & Plane Flange (a) Drawing (b) Connecting association among components Fig. 1 Assembly model example 1: Two plates are fixed by a bolt 262 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 0.31, Feb. 17, 2000) 34 1.

In the figure, the boxes and the circles describe the components (assemblies, subassemblies, and parts) and the hierarchical associations (parent-child associations) among the component definitions, respectively. The hierarchical associations are classified into two types. (1) main_component_usage This entity represents the parent-child associations between a pair of components, which are main and/or important components. (2) auxiliarycomponentusage This entity represents the parent-child association between a pair of components, which are additional, and/or auxiliary components such as fixing bolts, rivets and so on. In the case of the assembly shown in Fig. 1 (b), the hierarchical associations are as follows. (a) Assembly <- main_component_usage -> Flange plate (b) Assembly <- main component usage -> Base plate (c) Assembly <- auxiliary component usage -> Bolt The solid circles in Fig. 4 show the components associations (peer to peer associations) among the components (assemblies, subassemblies, and parts). For examples, all the arcs in Fig. 1 (b) and Fig. 3 represent the peer to peer associations. The details of the components associations are described by the assembly feature associations and the assembly features. 264 ISO 10303-1XX.XXXX ISO Assembly Model of Products (Ver. 031, Feb. 17, 2000) 36 assembly sub-assemblyl sub-assembly2 sub-assembly3 sub-assembly4 sub-assembly5 parts part4 parti parti parti parti Assembly_feature_association Assembly_component_usage Components_association Assembly_feature1 Assembly_feature2 Fig. 4 Basic structure of assembly model 265 ISO 10303-1XX:XXXX ISO Assembly Model of Products (Ver. 0.31, Feb. 17, 2000) 37 Index (to be completed) ISO TC 184/SC4/WG3 N 830 Date: 99-11-8 Supersedes ISO TC 184/SC4AVG_3 ISO/ [ballot stage] [standard number] - [part number] - [ballot cycle] Document title : Proposal of Integrated AAM for Mechanical Design Manufacturing^) ABSTRACT: This document is proposal of Integrated AAM for Mechanical Design and Manufacturing.

Background We have investigated the data model to develop and manufacture mechanical product. Our main concern is how to deal with the data model through whole process of mechanical product life cycle. And our goal is to develop the technology and establish a standard for consistent data model of mechanical manufacturing process system. At the SC4 San Francisco meeting in January 1999, we presented “Proposal of Integrated AAM for Mechanical Design and Manufacturing (TC184/SC4/WG3 N773)”. In that document, we pointed out the following requirements by analyzing the whole process. (1) Need information for process chain (2) Development of Data model (APs) to support the consistency between mechanical design and manufacturing. (3) Separation of AP domains. We surveyed several related ISO standards from ISO 10303, ISO 14649, IS015531 and so on. These results were induced by analyzing AAM (Application Activity Model) of whole mechanical process. When we investigate and analyze the requirements, we adopt the fundamental STEP development methodology defined by STEP AP development guideline. This time we investigate the detail relationship of Develop Product Process output, Design Machining Process and Design Assembly Process. In this document we will explain the detail Design Machining Process for process planning and operation planning, and emphasize the difference between Product Model Data, which is output of Develop Product Process, and Machining Process Data Model used for Design Machining Process. 2. Conclusion We recognize the importance of different handling of model data between Develop Product process and Design Machining process. As follows, we depict data model and its process activity and its expected functional requirements. (1) Machining Process Data Model [The positions] Table 1. ’’Proposed machining Process Data Model ” shows the difference between Machining Process Data Model and other existing models. This new model can represent process planning and operation planning data. If the Form Feature of AP224 intend to be applied for Machining Process Data, we need discuss in detail. [The Functions] 1) Design Machining Process (A2): By using Product Model Data (output data model of Develop Product Process activity) and Model Data of Existing Machining Line, it can induce Process and Operation Planning Data. 2) Design Machining Line and Create Process Plan for Machining (A22): By using Form Feature based Product Model Data and Model Data of Existing Machine Line, it can induce Process and Operation Planing Data and Manufacturing Feature based Product Information. (A223,A225,A2231 ,A2232,A2233,A2235,A2251 ,A2252,A2253 will be explained later documentation.) 268 (2) Assembly Feature Data model [The Functions] 1) Design Assembly Process (A3) : - By using Model Data of Existing Assembly Line and Manufacturing Resource Data Model, it can get Tool requirements, Model Data of Assembly Line, Operation Planning Data for Assembly. 2) Capture Assembly Feature (A31): - By using Product Model Data, it can induce Assembly Feature Based Model Data 3. Summary • From this investigation, we propose the need of data model, which can be used in the design machining process activity related product model data. • For process and operation planning of Mechanical product, we must recognize the difference among Product Model Data, Machining Process Data Model and Data Model for Computerized Numerical Controller. 269 11 of Part 13399) shape (ISO Model Operation Operation Data.

Yoshiki Muta (Toyota Motor Corporation) Yasumasa Oku (JSTEP) Seishiro Takeuchi (JSTEP) Takamasa Ochiai (JSTEP) Masaharu Tsuchiya (JSTEP) 1. Background/Purpose JSTEP has analyzed activities to the production from the design of the machine product and proposed I-AAM (Integrated Application Activity Model) to clear the following. Whether STEP/Aps proposed until now can become Data Model of which activities, and activities to the production from the design, STEP, to support it, by which activities and what kind of Data Model is necessary. From this analysis work, we have pointed out that Data Model which supports Process planning/Operation planning which interconnects the design and the machining is lacked. This Discussion paper is the material to examine Data Model which is necessary for Operation planning which ties the machining to the design about only one product. We think Operation planning to be the reverse problem of Machining Operation, and the mathematical background is explained here with modeling of Machining Process and necessary Data Model. Also we show that this Data Model is available as Data Model of Operation planning. 2. Scope Machining Operation Information or List of Workingsteps should be inputted, and Machining Process Model until machining feature in the material is formed is made the target. In Scope: i. Machining Process Model 291 ii. Cutting Tool Model iii. Functional Model of Machine Tools iv. Functional constraints Model and Workingtool v. Machining feature model Out of Scope: i. Process Plan ii. Geometric Processing for generating NC data iii. Machining technologies and Machine functions such as coolant and etc. 3. Why do we discuss a machining process model? We showed the relations of the standard which relates to the relations of the input/output in Process planning or Operation planning and Machining feature being under consideration at present in ISO in Figure- 1. Our understanding is arranged as follows. 1) We understand that machining feature that it is defined with AP224, AP214 is the standard to express the input data of the Process planning/Operation planning system mainly. (Contain an output data by the case, too) 2) On the other hand, we understand that ISO 14649 (ISO/TCI84/SC 1/WG7 : CNC Data Model) is the standard to prescribe the type of the output of Process planning/Operation planning or the input of the CNC device. We hopes for the discussion which clears the part of the Machining feature definition of AP224, AP214 and ISO 14649 first. We point out that the following examination is necessary in the case that if Machining Feature in each standard aims at the above-mentioned part. 1) You must be able to express the thing formed by given machine tools and tools and machining technologies with Machining feature in ISO 14649 which is the output expression standard of Process planning/Operation planning. 2) Machining feature of AP224,AP214 which is the input data of Process planning/Operation planning must be converted into ISO 14649 as an output of Process planning/Operation planning. If we say conversely, machining feature of AP224, AP214 must be converted into Machining feature of ISO 14649 as an output. With this Paper, first, we pay attention to an examination item 1) and analyze the relations between shape of cutting edge,the functional model of machine tools and functional constraint 292 condition (constraint of rotational motion and translational motion) and volume surrounded by envelope, envelope of cutting edge due to the rotation/translation of tools, working edge mathematically, and then propose Machining Process Model. We explain potential Machining feature (Contain Machined Surface / Surface Texture) and the definition necessary condition by Shape of cutting edge (Contain a compound cutting edge) and the tool movement to use with this Machining Process Model .

Summary In this paper we limit it to the Process planning/Operation planning activities which are necessary for the information conversion to Machining Operation Information from the Design Information of the machine product, and we pointed out the need to examine about the part of Machining feature, especially the part of Machining feature of AP224, AP214, ISO 14649 which becomes the core of the input and output information about those activities. And, in this report, we pointed out that Machining feature should be defined based on the Machined Surface formed when a tool is driven, and we expressed the form of cutting edge, Functional Model of machine tools, generated Machining feature and those relations based on the mathematical model of Machining Process. We think that it is possible to use these Shape of cutting edge expressions, Functional Model of machine tools, generated Machining feature as Data Model in Operation planning. 320 ISO TC 184/SC4/WG3 N 870 Date: 2000-2-14 Supersedes ISO TC 184/SC4/WG3/N830 ISO TC 184/SC4/WG3/N831 ISO/ [ballot stage] [standard number] - [part number] - [ballot cycle] Document title: Need of Machining Process Data Model______ABSTRACT: This document is concerned with Machining Process Data Model for manufacturing mechanical parts. By considering the whole process for manufacturing, we point out the lack of important mechanical manufacturing process chain. From the point of view of manufacturing process, we point out the difference between Form Feature defined by AP224 and Manufacturing Feature defined by IS014649. And we point out the lack of data model to describe process plan data and the need for upgrade of Manufacturing Feature Model. We propose the need of New Machining Process Data Model for manufacturing mechanical parts.
