METHOD AND APPARATUS FOR CONTROLLING A SURFACE SCANNING COORDINATE MEASURING MACHINE

A method improves surface scanning measure machine speed while minimizing tip touchdown impact on the surface of the object being measured. Specifically, the method controls a surface scanning measuring machine having a probe head with a distal probe tip that contacts the surface of an object to be measured. To that end, the method selects a nominal initial contact point (on the surface) having a normal vector, and then moves the distal probe tip toward the nominal initial contact point along an approach path. The approach path has a generally linear portion that generally linearly extends from the nominal initial contact point to some non-contacting point spaced from the surface. The generally linear portion forms an angle of between about 20 degrees and about 60 degrees with the normal vector.
