- Abstract:
- This paper presents a new calibration method for larger size co-ordinate measuring machines (CMMs). This method provides 21 parametric errors by performing 1-dimensional length measurements in the workspace of a CMM. A special measurement set up is realised, which enables automated volumetric error compensation of CMMs at their production stage. Located in a corner of the measuring volume, this laser set up performs multiple spatial linear interferometer measurements by movement of a CMM automatically. In this paper emphasis is placed on; i) automation of spatial laser interferometer measurements, ii) minimising cosine errors by optimisation of the interferometer signal, iii) measurement strategy and iv) verification of the calibration.
