3.2.2

Calibrate probe - length (CYCLE973)

Function
Only applies on a turning machine without the milling technology.
With this measuring version, a workpiece probe with cutting edge positions SL=5 to 8 can be
calibrated on a known surface (workpiece-related). The trigger points of the probe are
determined.
Optionally, the actual length can be entered in the tool offset memory via the "Adapt tool length"
parameter.
Measuring principle
The switching position of the workpiece probe in an axis is calculated into the measuring probe
length. The calculated trigger point is determined in the corresponding axis and axis direction,
and entered in the selected calibration data set (calibration data field) of the workpiece probe.
The probe travels in the measuring direction to the calibration edge (e.g. workpiece)

Requirements
● The surface must be in parallel to an axis of the workpiece coordinate system (WCS).
● The calibration surface must have a low surface roughness.
● The workpiece probe is called as tool with tool offset.
● 580 must be declared as the probe type.
● Calibrating the probe length does not represent measuring the tool. The deviation between
the physical probe length and the values in the tool data must be less than 5 mm / 0.2 inch.
Starting position before the measurement
The probe must be positioned opposite to the calibration surface.
