Objective:

• Provides students with a robust opportunity to apply CAD/CAM principles by designing and manufacturing a tangible product using CNC machining, enhancing practical skills and expertise in engineering design and production processes.
• Design a product and create a digital model using CAD software, then generate a manufacturing program using G-code for CNC machining.
• Document the design process and outcomes in a written report.

Project Overview: Product Design:

• Select a product to design, such as a mechanical part, tool, component, or any other object of interest. The design should showcase creativity, functionality, and manufacturing feasibility.

CAD Modeling:

• Use CAD software (Crew) to create a detailed 3D model of the chosen part on a workpiece with dimensions of 100x100x20 mm, including your name on the same workpiece (name should not exceed 80 mm in length and 10 mm in extrusion).
• Ensure the model accurately represents the dimensions, features, and specifications of the part. If scaling is necessary, take into account the workpiece dimensions.

CAM Programming:

• Generate a manufacturing program using Crew software, defining toolpaths, cutting strategies, feeds, speeds, and other parameters necessary for CNC machining, following these instructions:
  1. Facing operation:
     • Tool diameter: 12 mm
     • Feed rate: 150 mm/min
     • Clear distance: 0.5 mm
     • Step depth: 4 mm
     • Spindle speed: 1000 RPM
  2. Finishing operation:
     • Tool diameter: 4 mm
     • Feed rate: 200 mm/min
     • Step depth: 1 mm
     • Clear distance: 0.5 mm
     • Spindle speed: 1500 RPM
  3. Coordinate system should be selected at one of the workpiece corners (mandatory).

G-code Generation:

• Export the manufacturing program from Crew software in G-code format (TXT file), ensuring it is optimized for efficiency, accuracy, and safety during machining.

CNC Machining:

• Operate a CNC machine to produce the designed product under the supervision of the instructor. Load the G-code program with instructor supervision, set up the workpiece and tooling, and initiate the machining process.
• Throughout machining, monitor the operation, make any necessary adjustments, and ensure the quality of the finished part.
