  • Integrated System for Machining Process Visualization and Analysis in Blade Applications
    Master Thesis LUTMDN(TMMV-5274)/1-57/2016SE Integrated System for Machining Process Visualization and Analysis in Blade Applications Pontus Westlin 2016 DEPARTMENT OF MECHANICAL ENGINEERING LUND INSTITUTE OF TECHNOLOGY ii Abstract The manufacturing industry is heading towards a more digitized environment. Sandvik Coromant is therefore developing intelligent tools, as well as software tools for machining applications. The aim for this thesis is to develop the understanding of a specific machining process. This is done through a background study of previously known methods, followed by development of a demonstrator to integrate machining data, and finally a case study to visualize a process. Continuous development of methods and approaches are required to provide efficient manufacturing processes. Simulations of a machining process is a helpful tool to gain knowledge about relationships between process data and the machining results. Verifying the simulation results is a challenge, especially since every applications has its own requirements. Therefore, a case study is performed during this thesis work for the selected application. A demonstrator for an integrated system has been developed using Integrated Feature based Metrology (IFM), which is an internally developed concept for connecting data from different machining stages. Pre-process data (digital models and process plans) is connected to in-process data (feed, speed, cutting forces etc.) as well as post-process data (geometric evaluations of the finished component). Deviations and correlations that can cause machining problems can be detected and analyzed through alignment of these types of data. The developed demonstrator shows that it is possible to connect data from the three machining stages.

  • Software Development from Theory to Practical Machining Techniques
    Software development from theory to practical machining techniques Khashayar Shahrezaei Pontus Holmström Mechanical Engineering, master's level 2020 Luleå University of Technology Department of Engineering Sciences and Mathematics Abstract In already optimized processes it may be challenging to find room for further improvement. The solution can be found in the advanced software and tools that support the digital manufacturing, all the way from planning and design to in-machining and machining analysis. This project the- sis focuses on developing a process methodology to transcribe Sandvik Coromant's theories and knowledge about machining operation grooving into machine-readable formats. Various software development models have been analysed and a particular model inspired by the incremental and iterative process model was developed to match the context of this project. This project thesis describes the working methodology for gathering theories and translating them into machine-interpretable format. A working methodology developed in this project thesis succeeded in transcribing different human- readable theories such as people's minds (experts within the field) and handbooks into a machine- interpretable format. The proposed algorithms for tool path generation was developed and imple- mented successfully through the integration of mathematical modelling. MATLAB R and Siemens NX has been used to build a proof of concept environment. Acknowledgements This report is created in our thesis work and as the last step in our Master of Science education in Mechanical Engineering at the Lulea University of Technology. We would like to thank our supervisors from Sandvik Coromant, Marko Stugb¨ak,Fredrik Selin, Pontus Westlin and Stefan Wernh for their guidance and encouragement in our work.

  • 4 Cutting-Tool Trends in Metalworking and Manufacturing
    Machining 4 Cutting-Tool Trends in Metalworking and Manufacturing Kip Hanson | Dec 24, 2019 Two of the leading cutting-tool makers prepare for the future of part-making. We take a look at recent innovations—with a close eye on where tools are heading. From proprietary aerospace metals to polymers and carbon fiber composites to 3D-printed parts from metal powders, the materials of tomorrow are evolving. Where are the cutting tools and toolholders to handle these materials heading? Will cost, tool life or predictability be the driving factor of new tool development? How important will real-time feedback from tools become? Is Industry 4.0 and the Industrial Internet of Things only hype, or are we at the cusp of a game-changing evolution in metalworking technology? Whatever the outcome, cutting-tool suppliers and manufacturers are embracing this brave new world. Cutting-Tool Trend #1: Internet of Things Integration Anyone who’s not asking these questions might look back 10 years from now and wish they’d done things far differently. Not only are most cutting-tool makers cranking out new carbides, coatings and geometries at breakneck speed, but many expect digitalization to become the clear path forward for shops wishing to increase productivity in the face of a more technologically minded workforce. Among them is Sandvik Coromant. The company has been quite busy developing an entire ecosystem of dashboards and visualization tools to help customers leverage the supposed benefits of Industry 4.0 and the IIoT. Its CoroPlus connected-solutions platform, for example, promises to deliver never-before- possible insights into machine tool utilization and other efficiency metrics.

  • Automatic Tool Selection System Based on STEP NC and ISO13399 Standards
    VOLUME 5 NO 4, 2017 Automatic Tool Selection System based on STEP_NC and ISO13399 Standards Hanae Zarkti1, Ahmed Rechia1 and Abdelilah El Mesbahi1 1Department of Mechanical Engineering, Faculty of Sciences and Technics, Tangier, Morocco. [email protected], [email protected], [email protected] ABSTRACT Computer Aided Process Planning (CAPP) is considered as an essential component of Computer Integrated manufacturing (CIM) environment and it is an important interface between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM). The purpose of the CAPP is to determine automatically the use of available resources, including machines, cutting inserts, holders, appropriate machining parameters such as cutting speed, feed rate, depth of cut, and generates automatic sequences of operations and instructions to convert a raw material into a required product, with good surface finish. The contribution of this work in CAPP field is the development of an automatic tool selection system based on STEP_NC and ISO 13399 standards for turning and milling processes. The paper presents the result of study and analysis of principal system functionalities to be considered. The system consist of four principal modules: a Tool database, feature recognition module, cutting tool selection module and a process optimization module. Finally, based on functional analysis results, the paper present the development of tool database and data tool extraction module from ISO 13399 File using oriented object programing. Keywords­ CAPP; cutting tool selection; functional analysis; database; ISO13399; objected oriented programming; 1 Introduction The ultimate goal of the factory of the future is to interconnect every step of the manufacturing process. Today, fast paced technology, sustainability, optimization and the need to meet customer demands have encouraged the transformation of the manufacturing industry, to become adaptive, fully connected and to adapt new standards that involve technical integration of systems across manufacturing processes.
