Operating and Programming — Milling
Basic Theory
In DIN mode, the tool length is
activated automatically, but in ISO
mode, you must activate the tool
length via G code.
G43/G44
and
G49
Use G43/G44,the tool length
compensation value will be
activated.
G43
: Tool length compensation in
positive direction
G44
: Tool length compensation in
negative direction
G49
: Cancel tool length

You can specify the circle end point in the
following X/Z address for both. You can
also describe circle radii with I, J, K
incremental or use parameter R to specify
radii directly.
Method 1 (use incremental to describe
circular radius)
