Wear compensation of tool radius

Contour grinding

The wear compensation of the tool radius (radius compensation) is used if a contour with active tool radius compensation shall be processed.

The wear of the grinding wheel in the direction of the disk radius can be compensated continuously or discretely.

For the processing type radius compensation the wear is only considered with active tool radius compensation (TRC).

The following figure shows the wear of tool radius:

Figure 1-2: Wear compensation of tool radius
Wear compensation of tool radius 2:

The starting movement to the equidistant path after selection of TRC (G41/G42) is assumed without wear.
The movement after deselection of TRC (G40) is also without wear.

Notice

The selection/ deselection of TRC has to be programmed during active radius compensation.
