Milling with working plane G17
TOFRAME or TOROT defines frames whose Z axes point in the tool direction. This definition
is tailored to milling operations, for which working plane G17 X/Y of the 1st – 2nd geometry
axis is typically active.
Turning with working plane G18 or G19
Turning operations in particular, and active G18 or G19 in general, require frames, with
which the tool is aligned in the X or Y axis. A frame of this type can be defined with G codes
• TOFRAMEX TOROTX
• TOFRAMEY TOROTY
• TOFRAMEZ
TOROTZ. This functionality of TOFRAME and TOFRAMEZ or TOROT and TOROTZ is
identical in each case.

Frame rotation ON Z axis parallel to tool orientation
Frame rotation ON Y axis parallel to tool orientation
Frame rotation ON X axis parallel to tool orientation
Align workpiece coordinate system (WCS) on workpiece.
Translations, scaling and mirroring in the active frame
remain valid. The workpiece-related frame rotation
activated with PAROT is deactivated with PAROTOF.
