Measure tool (CYCLE971)

Function
With this measuring version, the tool length or the tool radius of milling and drilling tools can
be measured. A check is made whether the difference to be corrected in the entered tool
length or to the entered tool radius in the tool management lies within a defined tolerance
range:
● Upper limit: Safe area TSA and dimensional difference control DIF
● Lower limit: Work offset range TZL
When this area is maintained, the measured tool length or the tool radius is entered in the
tool management, otherwise a message is output. Violation of the lower limit is not corrected.
Measuring is possible either with:
● stationary spindle (see Section "tool measurement with stationary spindle")
● rotating spindle (see Section "tool measurement with rotating spindle")
