PURPOSE:To permit dynamical operations of the coordinates on the outside shape of an object to be measured at the points where a probe abuts thereon by detecting the moving directions of the probe in the stage of abutting together with the coordinates of the probe positions at the points where the probe abuts. CONSTITUTION:The probe 14 of a three-dimensional measuring machine outputs a touch signal 100 by means of a touch sensor 30 combined with the probe 14 when the probe abuts on an object to be measured. The extents of movements or the positions in the respective axis directions of the probe 14 are detected by the X encoder 32, Y encoder 34, and Z encoder 36 built into the moving body of the probe 14, and these detection signals are arithmetically processed by an arithmetic circuit 38 for probe positions, whereby the positions of the probe 14 are detected at all times. The moving directions when the probe 14 abuts on the object are discriminated by a direction discriminating circuit 42, and are supplied to an arithmetic circuit 44 for coordinates together with the coordinates of the probe positions of a reading circuit 40 for coordinates. |
