G2Writing programs
Overview
The MILLPWRG2  allows many features to be used without having to 
write a program. For operations that repeat, or complex machining it 
is best to write a program. Before writing a program, determine the 
work-holding device and the location of Part Zero (the point to which 
all movement is referenced). Since absolute positions are defined 
from Part Zero, try to select a location that directly corresponds to 
dimensions provided on the part print,...
