COURSE OBJECTIVES:
1. To gain practical experience in handling 2D drafting and 3Dmodelling software systems
2. Designing 3 Dimensional geometric model of parts, sub-assemblies, assemblies and exporting it to drawing
3. Programming G & M Code programming and simulate the CNC program and Generating part programming data through CAM software

3D GEOMETRIC MODELLING: 30
1. CAD Introduction
      Sketch:
      Solid modeling: Extrude, Revolve, Sweep, Variational sweep and Loft.
      Surface modeling: Extrude, Sweep, Trim, Mesh of curves and Free form.
      Feature manipulation: Copy, Edit, Pattern, Suppress, History operations.
      Assembly: Constraints, Exploded Views, Interference check
      Drafting: Layouts, Standard & Sectional Views, Detailing & Plotting
2. Creation of 3D assembly model of following machine elements using 3D Modelling software
      1. Flange Coupling
      2. Plummer Block
      3. Screw Jack
      4. Lathe Tailstock
      5. Universal Joint
      6. Machine Vice

* Students may also be trained in manual drawing of some of the above components (specify the number – progressive arrangement of 3D)

MANUAL PART PROGRAMMING: 30
1. CNC Machining Centre
      i) Linear Cutting.
      ii) Circular cutting.
      iii) Cutter Radius Compensation.
      iv) Canned Cycle Operations.
2. CNC Turning Centre
      i) Straight, Taper and Radial Turning.
      ii) Thread Cutting.
      iii) Rough and Finish Turning Cycle.
      iv) Drilling and Tapping Cycle.
3. COMPUTER AIDED PART PROGRAMMING
      i) Generate CL Data and Post process data using CAM packages for Machining and Turning Centre.
      ii) Application of CAPP in Machining and Turning

TOTAL:60 PERIODS

OUTCOMES: At the end of the course the students would be able to
1. Design experience in handling 2D drafting and 3D modelling software systems
2. Design 3 Dimensional geometric model of parts, sub-assemblies, assemblies and export it to drawing
3. Demonstrate manual part programming and simulate the CNC program and Generate part programming using G and M code through CAM software.
