Assignment:
Write the part program to drill the holes in the part shown in Figure. The part is 12.0mm thick. Cutting speed = 100 m/min and feed = 0.06 mm/rev. Use the lower left corner of the part as the origin in the x-y axis system. Write the part program in the word address formal with TAB separation and variable word order. Use absolute positioning. The program style should be similar to Example.
Example: This example presents the NC part program in word address format for drilling the three holes in the sample part shown in Figure. We assume that the outside edges of the starting workpart have been rough cut (by jig sawing) and are s1Jgbtly oversized for subsequent profile milling.
Sample part to illustrate NC part programming. Dimensions are m millimeters. General tolerance = ±0.1 mm. Work material is a machinable grade of aluminum.
Provide complete and step by step solution for the question and show calculations and use formulas.
