Probing Functions For Datum Setting; Datum Setting With The Edge Finder - HEIDENHAIN ND 780 Handbuch

Probing Functions for Datum Setting

The ND 780 supports a HEIDENHAIN Electronic 3D, KT 130 Edge
Finder connected through X10.
The ND 780 also supports a grounding type edge finder connected via
the 3.5 mm Phono Jack on the back of the unit. Both types of edge
finders operate the same way.
During probe functions, the display freezes with the
location of the edge, centerline, or circle center.
The following probing soft key functions are available:
Workpiece edge as datum: EDGE

Centerline between two workpiece edges: CENTER LINE

Center of a hole or cylinder: CIRCLE CENTER

In all probing functions, ND 780 takes into account the entered stylus
diameter.
To abort the probing function while it is active, press the C key.
