Important functions for 3- to 5-axis machining
The properties of the compensations for face milling are compared in the table.
CUT3DF
(SINUMERIK 840D sl and powerline)
Calculation of the tool compensation in the
control/CNC
Supplementary conditions
Can be used with G64/G642/G645
Can be used only to a limited extent with
compressor:
COMPCAD - Advanced Surface
COMPSURF - Top Surface
We recommend the use of the CUT3DFD function for face milling.
Programming face milling with CUT3DFD
CUT3DFD can be used without additional tool orientation as 3-axis program, purely based
on the surface normal vector.
CUT3DFD G41 G01 X145.983 Y99.000 Z-20.876
CUT3DFD can be used as 5-axis program with various types of tool orientation (TRAORI
active!)
Direction vector

C5=0.357
Round axis values
CUT3DFD G41 G01 X145.983 Y99.000 Z-20.876
The CUT3DFD 3D radius compensation acts for all tool types for machining free-form
surfaces.

CUT3DFD
(SINUMERIK 840D sl as of V4.8 SP2)
Calculation of the tool compensation /
standard tool in CAD/CAM and calculation
of the difference by entering the wear in the
control/CNC.
Supplementary conditions
Can be used only with compressor:
COMPSURF - Top Surface
The tools should have maximum 5-10%
negative wear of the standard tool.
