Machine - part Coordinate System |
Step 2 of 7

| All probing
points determined during stylus qualifications refer to the machine
coordinate system of the CMM. This
is a coordinate system specified ex works (in parallel to the
CMM
axes).
|
|
In practice, however,
coordinates are required that refer to the parts, as specified in the
technical drawing (see example below).
|
| This is why, prior to
measuring the individual standard geometric elements, first the associated
part coordinate system has to be determined.
