Measuring Cycles for Milling and Machining Centers
5.4 CYCLE977 workpiece: Measure hole/shaft/groove/web/rectangle parallel to axes
Options for hole and shaft diameter, groove or web width, and tool compensation.
• An empirical value from data block GUD5 can be included with the correct sign.
• A mean value can be derived from several workpieces, measurement calls.
Prerequisite
The probe must be called as a tool with a tool length offset.
Tool type, preferably: 710
When using the cycle on a turning machine: set type 5xy and _CBIT[14]=0.
