Setting Zero Offsets
What is Zero Offset?
The common coordinate position from which a complete program is made for a particular compo-
nent is termed "zero point or program zero".
The program zero is located at the fixed position (center of the spindle) on the X-axis. However, the
program zero on the Z-axis will vary depending on the setup (incl. chuck, jaws, etc.) as indicated
with A' and B' in the figure below.
