7.13 “G107” CYLINDRICAL INTERPOLATION
The cylindrical interpolation function G107 allows programming taking into consideration the total length of
the plane of the side surface of a cylinder; therefore, this is very useful to program splines of cylindrical
cams performed on the skirt of the workpiece (interpolating axes Z and C) and using a radial motor driven
module.
To enable and disable function G107 the procedure is as follows:
G1 G18 W0 H0 Specifies that work starts interpolating axis Z with axis C (W and H are the
incremental values of Z and C)
G107 C…. G107 activates the cylindrical interpolation mode, C.. specifies the radius of the
piece to be worked, it serves for the feed speed calculation G94 F in mm/min
according to the milling radius (as the working radius increases the spindle will
turn more slowly) The value of C is used also for the calculation of the new
transferred profile of the milling radius when the milling radius offset G41 or G42
is activated,
