Probing Functions for Datum Setting
It is particularly easy with a HEIDENHAIN KT 130 Edge Finder (Fig.
I.20).
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
With Circle Center, the hole must be in a main plane. The three main
planes are formed by the axes X / Y, Y / Z and Z / X.
The POSITIP 880's probing functions enable you to set datum points
with a HEIDENHAIN KT Edge Finder. The probing functions are also
available when you are using a tool instead of an edge finder.
