; Feed of the tool.
; Approach the starting posi-
tion.
; Axes X/Y are path axes, Z is
a synchronized axis.
; On the circular path, the
feedrate is 1,000 mm/min, tra-
versing in the Z direction is
synchronized.
; The limit speed is deselec-
ted by reading the speed from
the MD. Read the value from
the MD.
