1.3 Modes of Operation
The TNC offers the following modes of operation for the various
functions and working steps that you need to machine a workpiece:
Manual Operation and Electronic Handwheel
The Manual Operation mode is required for setting up the machine
tool. In this operating mode, you can position the machine axes
manually or by increments. Datums can be set by the usual
scratching method or by using the TS 220 triggering touch probe.
The TNC also supports the manual traverse of the machine axes
using a HR electronic handwheel.
