11.3 Improvements in tool radius compensation
COMTYPE (P74) From this version on, this g.m.p. has three digits.
• The units set the type of beginning/end of tool radius compensation
applied by the CNC.
• The tens indicate whether the additional compensation block is
executed at the end of the current block or at the beginning of the
next block with compensation.
• The hundreds indicate whether the compensation is activated in
the first motion block or not, even if the plane axes are not involved.
It is also applied when the compensation is canceled.
After activating the compensation, it could happen that the plane
axes do not get involved in the first motion block either because
they have not been programmed or because the same point as the
tool position has been programmed.
In this case, the compensation is applied at the tool position as
follows. Depending on the first movement programmed in the
plane, the tool moves perpendicular to the path to its starting point.
The first movement programmed in the plane may be linear or
circular.
xx0 It approaches the starting point going around the corner
xx1 It goes directly perpendicular to the point (without going
around the corner)
COMPTYPE=xx0 COMPTYPE=xx1
x00 It is executed at the end of the current block.

compensation.
COMPTYPE=x00
Executing block by block (single
block mode), the first movement
ends at point "B".
COMPTYPE=x10
Executing block by block (single
block mode), the first movement
ends at point "A".
0xx The compensation is activated in the first block having a
movement of the plane axes.
1xx The compensation is activated in the first motion block even
if there is no movement of the plane axes. For example,
when program ming the same point twice or a zero
incremental movement.
