Measuring variants
3.5 Measure tool (turning)
Values are corrected without empirical and mean values.
Note
If a special calibration tool is not available, a turning tool can be used instead with cutting edge
positions 1 to 4 for the calibration of two sides of the probe.
Measuring principle
Calibrating with tool type calibration tool (type 585)
The calibration tool is shaped (angled) in such a way that the probe can be calibrated on all
four sides with it.
Calibrating with tool type calibration tool (type 725) or turning tool (type 5xy)
When a turning tool or a calibration tool, type 725, is used, the probe can only be calibrated
from 2 sides.
Calibrating the tool probe with a calibration toolCalibrating a tool probe with a turning tool
The cycle positions the calibration or turning tool to the probe. With a cycle call, the switching
position in the specified measuring axis and measuring direction is calibrated.
Preconditions
● Lengths 1 and 2 and the radius of the calibration or turning tool must be known exactly and
stored in a tool offset data record.
This tool offset must be active when the measuring cycle is called.
● For calibration, a reference turning tool, type 5xy, with precisely known geometry or a type
585 or type 725 calibration tool can be used (type 580 3D probe turning cannot be used)
● Calibration with a calibration or turning tool with cutting edge positions 1 to 4 is possible.
