Example of concatenating frames
Chaining of MEAFRAME for offsets
The MEAFRAME( ) function provides an offset frame. If this offset frame is concatenated
with a set frame $P_UIFR[1] that was active when the function was called, e.g., G54,
one receives a settable frame for further conversions for the procedure or machining.
Concatenation with ADDFRAME
If you want this offset frame in the frame chain to apply at a different position or if other
frames are active before the settable frame, the ADDFRAME( ) function can be used for
chaining into one of the channel basic frames or a system frame.
The following must not be active in the frames:
• Mirroring with MIRROR
• Scaling with SCALE
The input parameters for the setpoints and actual values are the workpiece coordinates.
These coordinates must always be specified
• metrically or in inches (G71/G70) and
• with reference to the radius (DIAMOF)
in the basic system of the controller.
