3D probe (multi probe)
Display
1) Workpiece measurement, length reference of the 3D probe
The tool length in the direction of the infeed axis (for G17: Z axis) is defined as the distance between
the tool reference point in the tool adapter and a parameterized reference point on the probe sphere.
The reference point can be set to the center of the sphere or the surface of the sphere using the following
machine data: MD51740 $MN_MEA_FUNCTION_MASK, bit 1
Mono probe
Display
1) Workpiece measurement, length reference of mono probe
The tool length in the direction of the infeed axis (for G17: Z axis) is defined as the distance between
the tool reference point in the tool adapter and a parameterized reference point on the probe sphere.
The reference point can be set to the center of the sphere or the surface of the sphere using the following
machine data: MD51740 $MN_MEA_FUNCTION_MASK, bit 1
As initial state for the measuring cycles it is defined that at spindle position 0° the switching
direction of the mono probe in the machining plane is aligned in the axis direction +X. If an
angular offset is required, then the value should be entered into tool parameter "Correction
angle" ($TC_DP10).
