Transformations
6.6 Compression of the orientation (COMPON, COMPCURV, COMPCAD)
Job planning
356 Programming Manual, 07/2010, 6FC5398-2BP40-0BA0
Activation/deactivation
Compressor functions are activated using the modal G codes
COMPON, COMPCURV or COMPCAD.
COMPOF terminates the compressor function.
See "
NC block compression (COMPON, COMPCURV, COMPCAD) (Page 248)".
Note
Orientation motion is only compressed when large radius circular interpolation is active (i.e.
tool orientation is changed in the plane which is determined by start and end orientation).
Large radius circular interpolation is executed under the following conditions:
• MD21104 $MC_ORI_IPO_WITH_G_CODE = 0,
ORIWKS is active and
the orientation is programmed as a vector (with A3, B3, C3 or A2, B2, C2).
• MD21104 $MC_ORI_IPO_WITH_G_CODE = 1 and
ORIVECT or ORIPLANE is active.
The tool orientation can be programmed either as a direction vector or with rotary axis
positions. If one of the G-codes
ORICONxx or ORICURVE is active, or if polynomials for the
orientation angles (
PO[PHI] and PO[PSI]) are programmed, no large circle interpolation will
be executed.
