In recent years there has been growing commercialization of small size devices. The present work describes the method of three-dimensional measuring for small parts by low contact force. Small touch probe consists of quartz sphere (φ0.125mm), stylus (ength 2mm, φ0.lmm), cross sheet (thickness 0.01mm, width 1.25mm) and optical displacement sensor. Touch probe was able to detect the coordinate from transformation of cross sheet center, which was generated at the contact point. Probe touched the object surface, and x, y and z numerical values were obtained. Being employed ring gage, as test specimens, the standard deviation was 1μm.
