CAD/CAM Selection for Small Manufacturing Companies
CAD/CAM SELECTION FOR SMALL MANUFACTURING COMPANIES By Tim Mercer A Research Paper Submitted in Partial Fulfillment of the Requirements for the Master of Science Degree in Management Technology Approved for Completion of 3 Semester Credits INMGT 735 Research Advisor The Graduate College University of Wisconsin May 2000 The Graduate School University of Wisconsin - Stout Menomonie, WI 54751 Abstract Mercer Timothy B. CAD/CAM Selection for Small Manufacturing Companies Master of Science in Management Technology Linards Stradins 2/2000 71 pages Publication Manual of the American Psychological Association In today's fast paced world, CAD/CAM systems have become an essential element in manufacturing companies throughout the world. Technology and communication are changing rapidly, driving business methods for organizations and requiring capitalization in order to maintain competitiveness. Knowledge prior to investing into a system is crucial in order to maximize the benefits received from changing CAD/CAM systems. The purpose of this study is to create a methodology to aid small manufacturing companies in selecting a CAD/CAM system. The objectives are to collect data on CAD/CAM systems that are available in the market today, identify important criteria in system selection, and identify company evaluation parameters. Acknowledgements Thanks to Dr. Rich Rothaupt for introducing me to CAM, survey help, and providing guidance with CAD/CAM applications. Thanks to Dr. Martha Wilson for early revisions, survey help and overall guidance. Thanks to my good friend and soon to be Dr. Linards Stradins for his patience, leadership, and wisdom. His invaluable knowledge and dedication as my advisor has helped me both personally and academically. -

A New Era for Mechanical CAD Time to Move Forward from Decades-Old Design JESSIE FRAZELLE
TEXT COMMIT TO 1 OF 12 memory ONLY A New Era for Mechanical CAD Time to move forward from decades-old design JESSIE FRAZELLE omputer-aided design (CAD) has been around since the 1950s. The first graphical CAD program, called Sketchpad, came out of MIT [designworldonline. com]. Since then, CAD has become essential to designing and manufacturing hardware Cproducts. Today, there are multiple types of CAD. This column focuses on mechanical CAD, used for mechanical engineering. Digging into the history of computer graphics reveals some interesting connections between the most ambitious and notorious engineers. Ivan Sutherland, who won the Turing Award for Sketchpad in 1988, had Edwin Catmull as a student. Catmull and Pat Hanrahan won the Turing award for their contributions to computer graphics in 2019. This included their work at Pixar building RenderMan [pixar. com], which was licensed to other filmmakers. This led to innovations in hardware, software, and GPUs. Without these innovators, there would be no mechanical CAD, nor would animated films be as sophisticated as they are today. There wouldn’t even be GPUs. Modeling geometries has evolved greatly over time. Solids were first modeled as wireframes by representing the object by its edges, line curves, and vertices. This evolved into surface representation using faces, surfaces, edges, and vertices. Surface representation is valuable in robot path planning as well. Wireframe and surface acmqueue |march-april 2021 5 COMMIT TO 2 OF 12 memory I representation contains only geometrical data. Today, modeling includes topological information to describe how the object is bounded and connected, and to describe its neighborhood. -

Implementation and Evaluation of Kinematic Mechanism Modeling Based on ISO 10303 STEP
Implementation and evaluation of kinematic mechanism modeling based on ISO 10303 STEP Yujiang Li Master Thesis Royal Institute of Technology School of Industrial Engineering and Management Department of Production Engineering Stockholm, Sweden 2011 © Yujiang Li, March 2011 Department of Production Engineering Royal Institute of Technology SE-100 44 Stockholm Stockholm 2011 Abstract The kinematic mechanism model is an important part of the representation of e.g. machine tools, robots and fixtures. The basics of kinematic mechanism modeling in classic CAD are about to define motion constraints for components relative other components. This technique for kinematic modeling is common for the majority of CAD applications, but the exchange of kinematic mechanism between different CAD applications have been very limited. The ISO 10303 STEP (STandard for the Exchange of Product data) addresses this problem with the application protocol ISO 10303-214 (AP214) which provides an information model for integration of the kinematics with 3D geometry. Several research projects have tried to, as subtasks, implement the kinematic functionality of AP214. But until recently no one have been able to create a valid dataset to prove the standard’s applicability. In this research, a framework for integration of the STEP-based kinematic mechanism modeling with existing commercial CAx systems is presented. To evaluate how well the framework is able to be applied for industrial practices, two applications are developed to demonstrate the major outputs of this research. A pilot standalone application, KIBOS (kinematic modeling based on STEP), is developed to prove the feasibility for Java-based STEP implementation on kinematics and to provide comprehensive operation logic to manipulate the kinematic features in STEP models based on ISO/TS 10303-27 Java binding to the standard data access interface (SDAI). -

Abstract This report is the Phase I final report of the National Shipbuilding Research F'rogram (NSRP) project (Project Number 4-94-1) to evaluate world-class shipbuilders' existing CADICAMICIM system implementations. Five U.S. shipyards participated in this study along with personnel from University of Michigan, Proteus Engineering, and Cybo Robots. Project participants have backgrounds in design, computer-aided design (CAD), n~anufacturingprocesses, computer-aided manufacturing (CAM), production planning, and computer-integrated manufacturing/management (CIM). The results of this evaluation provided the basis for the CADICAMICIM Workshop presented in conjunction with the 1996 Ship Production Symposium, and will be used as background in Phase I1 of the project to develop requirements for future shipbuilding CADICAMICIM systems. -
21 Miscellaneous Companies
Chapter 21 Miscellaneous Companies Space restrictions simply do not permit me to go into the depth of detail I would like on every company that participated in the early days of the CAD industry nor cover numerous in-house systems developed at major automobile and aerospace companies. Readers will have to be satisfied with the brief descriptions included in this chapter and even then, I have only been able to cover what I consider to be the companies that had the biggest impact. There are hundreds if not thousands of companies that at one time marketed engineering design software. Some of the companies described in this chapter offered just software while other provided both hardware and software. While many have changed names, I have decided to list them alphabetically based upon the name they are best been known by along with earlier and subsequent name changes. Adra Systems (Matrix One) Adra Systems was founded in Lowell, Massachusetts in July 1983 by William Mason, who had been at Applicon from 1973 to 1983, most recently as vice president of operations, James Stenzel, who had been vice president of engineering at Hastech, Inc., and Peter Stoupas, who had earlier been a regional sales manager at Adage and had also worked for Applicon. Mason became the president and CEO, Stenzel the vice president of product development and Stoupas the vice president of marketing. Between 1983 and 1986, the company raised $11.6 million of venture funding from a number of firms including American Research & Development, the company that also provided the initial funding for Digital Equipment Corporation.
