ABSTRACT:
A probe coordinate system driving apparatus in which, in a coordinate measuring machine, a probe can be driven in a direction in conformity with the position of the probe to thereby facilitate probe driving operation through joy stick operation. There is provided a probe head capable of freely changing the probe position through setting elevation angle .alpha. and angle of traverse .beta., and unit direction vectors representing the axes of a probe coordinate system in conformity with the probe position are obtained on the basis of the angles set. Vectors obtained from the scalar product of three electric signals output from a joy stick operating unit through the operation by the operator and the three unit direction vectors are synthesized to calculate a drive vector, and the driving of the coordinate measuring machine is controlled in accordance with this drive vector.
