摘要: A non-contact surface roughness-measuring machine is provided which can avoid damage caused by collision with a workpiece and set roughness probe at an appropriate position relative to measurement of the workpiece. touch-signal are attached tip end arm coordinate measuring machine. stylus protruded detection probe, in protrusion amount within optimum distance surface. When probes brought close detects contact,
