PROBLEM TO BE SOLVED: To provide a method of detecting chips adhered to work with a simple configuration. SOLUTION: A sensing plate 2 is placed at ahead of a probe arm 6 fitted with a probe 7 at its tip so as to be aligned with the external appearance of work 20 when it is seen from the sliding direction of an external diameter measuring device 5, with a fixed gap in between. When a sliding mechanism 8 slides the external diameter measuring device 5 to measure a measurement portion 21, and a touch sensor 10 finds the occurrence of power conveyance between the sensing plate 2 and work 20, it is judged that a cut chip 30 adheres on work 20. Thus, only by adding the sensing plate 2 and the touch sensor 10 to the external diameter measuring device 5, it is possible to surely detect the cut chip 30 attached to work 20.
