Wear compensation of tool length

Grinding a surface

When the tool length is compensated (length compensation), wear is compensated in the direction of the 3rd main axis. This can take place both continuously and discretely. This procedure is used in particular for processing surfaces (surface grinding).

Programing Example

Distributing continuous wear on 2 main axes depends on the inclination of the grinding disc as described in section Inclined grinding disc.
