2.1. In manual part programing there are two positioning methods, discuss the two methods and give an example with an aid of a diagram [5] 125 10 dia., 2 holes 25 - 12 dia., 1 hole 25 rad. 8 dia., 3 holes 100 75 T 50 125 1 -100- 150- -175- -200- Figure 2: Component 2.2 The part in Figure 2 above is to be drilled on a turret-type drill press. The part is 15.0 mm thick. Three drill sizes will be used: 8 mm, 10 mm, and 12 mm, which 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 part as the origin in the x-y axis system. 2.2.1 Calculate the speed for each drill bit [3] 2.2.2. Write the part program in the word address format using absolute positioning. [22] 125 -50- -75-
