Universal Equation and Operationability for Multi-Position Error Separation Technique
Hong Mai · Nanotechnology and Precision Engineering · 2004
The measurement equation for multi position error separation technique is put forward, and the equation is universal for all the current multi step and multi point methods. The universal separation mode,“the first separating operation” together with“the second separating operation” is presented according to the way related to two different error mapping matrices. It is pointed out that the weight function is of consequence to inspect the reasonability of the designated parameter of “measurement separation system”. The operationability and applicability are analyzed via an example of multi step method in roundness error separation. It is concluded that error separating operation with equi angle multi step method is more applicable in time domain than in frequency domain.
