4. Write an APT NC Part program (milling and drilling) for the following work part. The outline of the part shown in Figure is to be profile milled using a 30 mm diameter end mill cutter. The part is 15 mm thick. Use the lower left corner of the part as the origin in the x-y axis system. The two holes are already drilled to fix the work part in the machine (no need to include in program). Use absolute positioning. The program style should be similar to the explanation in PPT. The expected answers – 1. To define all the positions of holes, curves and lines. 2.Movement of cutter outside the work part. 3.Step by step movements for drilling.

4. Write an APT NC Part program (milling and drilling) for the following work part.
The outline of the part shown in Figure is to be profile milled using a 30 mm diameter end mill cutter. The
part is 15 mm thick. Use the lower left corner of the part as the origin in the x-y axis system. The two
holes are already drilled to fix the work part in the machine (no need to include in program). Use absolute
positioning. The program style should be similar to the explanation in PPT. The expected answers – 1. To
define all the positions of holes, curves and lines. 2.Movement of cutter outside the work part. 3.Step by
step movements for drilling.
