introduction of B5.54
and ISO230-6 machine
tool performance measurement standards are increasing
the popularity of laser interferometer
diagonal, sequential step
diagonal or vector technique for the
calibration and compensation of
machine tool errors. Reported here is a
theoretical analysis of the
4 body diagonal displacement measurement, sequential step diagonal or vector
technique, and 3 axes linear displacement
measurement. The relations between the 21 rigid body machine positioning errors and the 4 body diagonal displacement
measurement; and the
sequential step diagonal
measurement; and the 3
axes linear displacementmeasurement
were derived. Based
on these relations, the
advantages and limitations of these
measurements have been analyzed. Click
