EXAMPLE B:
N1 G50 T51OO ;
N2 GOO TO1O1 M03 S1OOO ;
If the machining which was started by the
following program is interrupted and the
program is restarted without returning the
tool to the machining start point, the tool
correctly moves to the first approach posi–
tion.

COORDINATE
SYSTEM
This is because N1 G50 T51OO ; command
at point B performs coordinate system set–
ting with the following values to retain the
work coordinate system, thus keeping
approach position A unchanged:
X = (-20. ) + (80. ) = 60.
Z = (-27.5) + (40. ) = 12.5
EXAMPLE C :
This example shows a program for which the
replacement position of each tool is different
from each other, and the values for work
coordinate system setting .
