The part in Figure P6.7 is to be drilled on a turret-type drill press. The part is 15.0 mm thick. There are three drill sizes to be used: 8 mm, 10 mm. and 12 mm. These drills are to be specified in the part program by tool turret positions T01,T02, and T03. All tooling is high speed steel. Cutting speed = 75 mm/min and feed = 0.08 mm/rev. Use the lower left corner of the pan as the origin in the x-y axis system. Write the part program in the word address format with TAB separation and variable word order. Use absolute positioning. The program style should be similar to Example 6.1.

Example 6.1

This example presents the NC part program in word address format for drilling the three holes in the sample part shown in Figure 6.15. 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.
