1 Concordia University Department of Mechanical and Industrial Engineering INDU 411 - Computer Integrated Manufacturing Winter 2024 Lab Project Description 1. Description The objective of this project is to manufacture and assemble chess pieces. This is a team project where each team has three students. Within each lab session, a team will be assigned to 1.1. Chess piece machining/lathe Manufacture one of the following chess pieces: Pawn Bishop Queen Rook King The chess pieces are turned on a CNC lathe machine from a cylinder block of ¾” diameter x 3” long high- density plastic. The operation is performed on proLIGHT Turning Center which is a tabletop, two-axis, slant bed CNC lathe with threading and multiple tooling capabilities. A G/M code will be generated by the students according to the design features of each chess piece. To accomplish this, the ProLight CNC Turning Control Software will be used to simulate the tool path of the turning operations. 1.2. Assembly Base Machining/milling Manufacture an Assembly Base Fixture machined on the CNC vertical milling machine using G/M code programming. The operation is performed on The CNC Machining Center (workstation 2), a three-axis tabletop milling machine that you can run directly from the CIM manager or workstation personal computer. To generate G/M codes, ProLight CNC mill control software will be used. The raw material to manufacture the fixture is made of 3.5” x 2 .25 ” x ½” Plexiglas. 1.3. Robotic Assembly Operation The chess pieces are then inserted to a specific base to complete the product assembly. This operation is performed at the robotic assembly station where each team will be required to program pick and place operations for the assembly tasks. 1.4. Production scheduling and Optimization Finally, each lab session will run a mixed model production by generating an MRP-based order and generating a schedule that will be optimized by implementing scheduling/dispatching rules using OPENCIM software.
2 2. Project Schedule, Deliverable and Final Report The completion of the tasks described in section 1 will follow the following lab schedule: Table 1: Lab Project Schedule Lab # Week Date Topic Individual Assignments Project Deliverables (Around 2 weeks) 1 1 2 1/16/2024 Introduction to CIM, project description, and G codes for milling No individual assignments No group assignment 3 1/23/2024 2 4 1/30/2024 ProLight Milling and Turning Software and G code As indicated in Lab2_PPT Chess base G code 2/11/2024 2/18/2024 5 2/6/2024 3 6 2/13/2024 ProLight Turning Software and Lathe As indicated in Lab3_PPT Chess piece G code 2/25/2024 3/10/2024 7 2/20/2024 4 8 3/5/2024 Robotic Assembly Station Robot programming OPENCIM MRP system Robotic assembly exercise Robotic assembly program 3/17/2024 3/24/2024 9 3/12/2024 5 10 3/19/2024 Production scheduling and OPENCIM part

4 The final report is due on Thursday April 13, 2022. The report should include the following sections: 1. Title 2. T.O.C. 3. Introduction The introduction of the report should include the objectives, part definition and process plan. 4. CAD Drawings 5. G-Code with comments In addition to the explanation of G code lines you generate for each part, calculate the estimated machining time and cost for each piece. 6. Robotic Assembly Code with comments Describe the assembly plan for the chess piece and the assembly base. Include a description of the robot(s) used and give insights into the programming and jigs required for the assembly. The report must contain illustrations of robot positions and a copy of the robot program code. 7. Mixed model production and System optimization This section should include the process plan and part definitions for OPENCIM for your project and the results of experiments with different dispatching rules for the mixed model production run, i.e. production of all the chess pieces in your lab section. Create a value stream map for the system. 8. Conclusion A summary of the results should be included as well as a discussion of possible sources of error. Also, include any suggestions regarding lab improvement. Appendix --any raw data or drawings can be included in the appendix of the report.
