Check out CNC PROGRAMMING BASICS: A PRIMER FOR SKILLS/VICA CHAMPIONSHIPS - In

The following link will take you to a site where you can download, free a
good 42 page book, that takes a lot of questions out of CNC axis. I have found
it to be very helpful.

One thing that I have noticed in looking at various codes, it looks like
where you set your orgin, determines how the +/- commands are written.
Also a lathe and mill are handled differently, the lathe moves the tool to
the work, the mill moves the work to the tool, and one must understand this,
and how the point of origin effects the code.
Also most books seemed to be aimed at the mill, and usually with the point
of orgin in the lower left hand corner of the work, and with a lathe at the
tailstock end of the work, at the centerline.

THIS IS NOT A HARD AND FAST RULE. but be sure what the book/program, is
using for the origin to understand how the axis directions are set up.

PLEASE BE GENTLE ON ME.................................
