1 Amount of travel between A and B on the Y–axis
= (workpiece holder position) + (tool area/2) + d
– (current position A)
d: Avoidance operation offset (parameter No. 16561)
2 Amount of travel between B and C along the X–axis =
(X command value)
3 Amount of travel between C and D along the Y–axis
= (Y command position D) – (current position C)
