To detect contour violations in linear blocks, the direction of the programmed motion block is compared with the direction of the corrected motion block. If the directions are opposite, this means a contour violation. The movement opposite to the programmed direction is called compensation movement.
This type of motion was detected and the contour masking process activated.
See [PROG// Section: Limits of TRC]
The principle of the outline fading out consists of removing the loop from the corrected path. For this purpose, the contour masking buffers a certain number of blocks corrected via the TRC. If the tool radius compensation recognizes a balance movement with active outline fading out, she marks the motion block and continues with the calculation of correction.
