Measuring workpieces on milling machines, machining centers

Workpiece probe
On milling machines and machining centers, the probe is classified as tool type 1xy or 710
(3D probe) and must therefore be entered as such in the tool memory.
Entry in tool memory
Tool type (DP1):
Length 1 - geometry (DP3):
Radius (DP6):
Length 1 - basic measurement
(DP21):
The wear and other tool parameters must be assigned the value 0.
In _CBIT[14] you can set whether length L1 refers to the ball center point or the ball
circumference.
Note
_CBIT[14]
see Subsection 9.2.4 (central bits).
Calibration
A probe must be calibrated before it can be used. Calibration involves determining the
triggering points (switching points), positional deviation (skew), and active ball radius of the
workpiece probe and then entering them in special data fields _WP[ ] in data block
GUD6.DEF.
The default setting has data fields for 3 probes. Up to 99 are possible.
Calibration can be performed on holes of a known size or workpiece surfaces with a
sufficient form precision and low surface roughness.
