Abstract:
A surface-tracking measuring machine, comprising:a main body movable relative to a workpiece;a probe displaccably supported by the main body and having a tracer at an end thereof;a measuring force controller for controlling a measuring force applied to the probe;a displacement detector for detecting a displacement of the probe;a measuring force detector for detecting the measuring force applied to the probe;a controller for comparing a measuring force detected value detected by the measuring force detector and a previously commanded measuring force command value to control the measuring force detected value to be equal to the measuring force command value;wherein a mechanical path for connecting the tracer and the measuring force controller is provided between the tracer and the measuring force controller so that positions of the tracer and the measuring force controller are relatively changeable, the measuring force detector being a strain gauge disposed in the path.
