540 Manual Operation and Setup

14.4 Datum Setting without a 3-D Touch Probe

14.4 Datum Setting without a 3-D

Touch Probe

Note

You fix a datum by setting the TNC position display to the coordinates

of a known position on the workpiece.

Preparation

U Clamp and align the workpiece

U Insert the zero tool with known radius into the spindle

U Ensure that the TNC is showing the actual position values

Datum setting with a 3-D touch probe: (see page 563).
