6.8 Frame generation according to tool orientation (TOFRAME, TOROT,
PAROT)
Function
TOFRAME generates a rectangular frame whose Z axis coincides with the current tool
orientation. You can use this function to retract the tool after a tool breakage in a 5-axis
program without collision, simply by retracting the Z axis. The resulting frame describing the
orientation is written in the system variable for the programmable frame $P_PFRAME.
Only the rotation component is overwritten with TOROT in the programmed frame. All other
components remain unchanged.
PAROT aligns the workpiece on the workpiece coordinate system (WCS).
Machine manufacturer
The position of the two axes X and Y can be defined in MD21110:
X_AXES_IN_OLD_X_Z_PLANE where X is rotated about Z into the existing X-Z plane.
