Turning tool (CYCLE982)

Function
With this measuring version, the tool length (L1 and/or L2) of a turning tool with cutting edge
positions 1 to 8 can be determined. The measuring version checks whether the difference to
be corrected with respect to the old tool length lies within a defined tolerance range:
● Upper limits: Safe area TSA and dimensional difference control DIF
● Lower limit: Work offset range TZL
If this range is not violated, the new tool length is accepted in the tool offset, otherwise an
alarm is output. Violation of the lower limit is not corrected.
Measuring principle
For "complete" measuring, all lengths of a turning tool are measured:
● Turning tool with cutting edge positions 1 to 4: L1 and L2
● Turning tool with cutting edge position 5 or 7: L2
● Turning tool with cutting edge position 6 or 8: L1
If the turning tool has a cutting edge position 1 to 4, contact is made with the probe in both
axes of the plane (for G18 Z and X), whereby the measurement starts with the 1st axis of the
plane (for G18, Z). For cutting edge positions 5 to 8, a measurement is only performed in one
axis:
● Cutting edge position 5 or 7: 1. measuring axis for G18 Z
● Cutting edge position 6 or 8: 2. measuring axis for G18 X.
When measuring "axis by axis", the length of the turning tool in the parameterized measuring
axis is measured.

Preconditions
The tool probe must be calibrated, see Calibrate probe (CYCLE982) (Page 255).
