simplified calculation of coordinates in the process program.
The following table describes the relationship between G54~G59 Work
Coordinate System and setting values of X, Y, Z, A, B, C items of MCM
parameters 1~120. These coordinate parameters (work origins) correspond to
machine coordinates by setting the machine origin as zero, therefore the work
origin settings of work coordinates G54~G59 are as follows
An illustration is given taking X & Z 2 axes as the example:
