8.4 Maintain tool radius compensation at constant level, CUTCONON (SW 4 and higher)
Programming
CUTCONON
CUTCONOF
Explanation
CUTCONON
Activate the tool radius compensation constant function
CUTCONOF
Deactivate the tool radius compensation constant function (default setting)
Function
The "tool radius compensation constant" function is
used to suppress the tool radius compensation for a
number of blocks while retaining the difference
between the programmed and actual path of the tool
center point accumulated in previous blocks as an
offset.
This can be practical, for example, if several motion
blocks are required at the reversal points during line-
by-line milling but the contours (bypass strategies)
generated by the tool radius compensation are not
desirable.
It can be used according to the type of tool radius
compensation (2 1/2D, 3D face milling, 3D
circumferential milling).
Sequence
Tool radius compensation is normally active before
the compensation suppression and is still active
when the compensation suppression is deactivated
again.
The offset point at the end of block position is
approached in the last motion block before
CUTCONON.
All following blocks in which the compensation
suppression is active are executed without
compensation.
