Keep tool radius compensation constant (CUTCONON)

The "Keep tool radius compensation constant" function is used to suppress the tool radius

compensation for a number of blocks, whereby a difference between the programmed and

the actual tool center path traveled set up by the tool radius compensation in the previous

blocks is retained as the offset. It can be an advantage to use this method when several

traversing blocks are required during line milling in the reversal points, but the contours

produced by the tool radius compensation (follow strategies) are not wanted. It can be used

independently of the type of tool radius compensation (2

circumferential milling).
