Page 15: Wear Compensation Of Tool Length
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). TF5200 | TwinCAT 3 CNC Version: 1.02 Online tool compensation... -
