W5: 3D tool radius compensation
Comment
; Select orientation transformation.
; Call CYCLE832 with:
; Contour tolerance = 0.01 mm,
; Processing type: Top Surface with smoothing,
; Finishing with input of an orientation toler-
ance,
; Orientation tolerance = 1 degree
; The blocks N09 to N10 are the fast portion of
the approach movement to the workpiece with con-
stant orientation.
the approach movement is realized. The tool is
already close to the workpiece; furthermore, the
mold making settings (e.g. COMPSURF) from the CY-
CLE832 are now active (due to active G01). The
path of this so-called transient phase for the
mold-making behavior should be about 1000 times
the contour tolerance (10 mm in this example).
; From N22, the surface normal is completely de-
fined over the entire block for the first time
(i.e. surface normal at the end of the previous
block N21 is present, thus the surface normal at
the beginning of the block N22 and the surface
normal at the end of the block N22). Thus the
prerequisite for switching on the tool offset
with G41/G42 is fulfilled.
