Measurement

Overview

The TNC offers three cycles for measuring workpieces and setting the
datum automatically. To define the cycles, press the TOUCH PROBE
key in the Programming and Editing or Positioning with MDI operating
mode.

Reference system for measurement results

The TNC transfers all the measurement results to the result
parameters and the protocol file in the active coordinate system, or as
the case may be, the displaced coordinate system.
