machine can move to
the fixed position
defined by the machine
supplier automatically.

Moving to a
fixed position
The following functions can be
used to influence the operation
of the spindle:
M3
accelerate to programmed
speed clockwise
M4
accelerate to programmed
speed counter-clockwise
M5
spindle decelerate to stop
M19
orient the spindle to a
specific angular position.

can be used to pause the
tools’ movements during
operation
G04 F5
: Program pause of 5 s
This makes the surface of the
workpiece much smoother
