Measuring variants
3.5 Measure tool (turning)
The approximate tool dimensions must be entered in the tool offset data:
● Tool type 5xx
● Cutting edge position, cutting edge radius
● Lengths in X and Z
The tool to be measured must be active with its tool offset values when the cycle is called.
Starting position before the measurement
Before the cycle is called, the tool must be moved to the tool tip starting position, as shown in
the following diagram.
Figure 3-25
The center of the tool probe and the approach distance are calculated automatically and the
required traversing blocks generated. The center of the cutting edge radius is positioned at
the center of the probe.
