Edge distance - groove (CYCLE977)

Function
This measuring version can be used to measure a groove in a workpiece. The groove width
is measured and the groove center point determined. Measurements at an inclined groove
are also possible. To do this, an angle corresponding to the actual angularity of the groove
position should be entered into the parameterizing screen form. Probing at the groove edge
always takes place at right angles. A protection zone can be defined in the groove.
The measurement result (measurement difference) can be used as follows:
● Correction of a WO so that the workpiece zero point is in relation to the groove center
● Offset of a tool,
● Measurement without offset
Measuring principle
1 point at each of the opposite edges of the slot are measured based on the selected
measuring axis. The positive direction of the geometry axis is measured first.
From the two actual positions, taking into account the calibration values, the groove width is
calculated.
The position of the groove center as workpiece zero is determined corresponding to the work
offset selected to be corrected.
The measured difference of the groove width is used as basic variable for a tool offset, the
position of groove zero point, as basis of a work offset.
