XM-60 and XM-600 multi-axis calibrator

Appendix C

Sign detection

The XM system has six measurement channels:

•

3 channels (T1, T2 and T3) correspond to translations (linear

and straightness)

•

3 channels (R1, R2 and R3) correspond to rotations around

T1, T2 and T3

Roll

Pitch

Sign detection process performs the following:

•

Links the T1, T2 and T3 axes of the XM to the machine linear axes

•

Sets the sign (+/−) of the T1, T2 and T3 measurements

•

Sets the sign (+/−) of the R1, R2 and R3 measurements
