Perpendicular selection and deselection (G237) of TRC
In the case of use of the perpendicular mode of tool radius compensation there are no restrictions concerning the sequence of motion blocks like for the direct or indirect mode.
Its possible to enable the tool radius compensation for an individual motion block.
The selection of perpendicular tool radius compensation adds a linear motion block orthogonal to the programmed path. This block produces the distance between the corrected and the programmed path. The output of this block takes place before the first programmed motion block.
The deselection of the perpendicular tool radius compensation adds another linear motion block orthogonal to the programmed path. This motion block reverses the distance between the corrected and the programmed path.
