  • Page 21. Outline If you want to perform roughing or semi-finishing with a single tool, you may fine-adjust the tool compensation. Moreover, you may want to fine-adjust the setting of the workpiece origin offset that was already set up. This function can change the offset (such as tool compensation or work
  • Page 32.3 Changing the tool compensation This function can change the tool compensation identified by the offset number corresponding to T code specified during automatic operation. If there is no valid tool compensation (for example, when no T code has been issued since cycle start), no tool compensation
