Exercise 2: Turning & Facing Operations

Problem Definition:- Write the part program in word address format, for the part shown below using only

G00 and G01. Write comments for each logical block of information in the part program.

Draw sketch on a graph paper to show work datum, various processing step & tool path.

Prepare the process plan in the format shown blown. Simulate the part program on

simulation software then produce it on CNC machine.
