    摘要: A measurement system of the invention includes a measuring instrument, a measurement control device, and a ranging device that is connected to the measurement control device. The measuring instrument includes a base that is to be fixed to a tool shaft, a cutter holder, or a tailstock of the machining apparatus, a first rod and a second rod that are connected to the base, and a first measuring head and a second measuring head that are fixed to the respective rods and irradiate an object to be measured with measurement light. The measurement control device (1) acquires a distance I between the first measuring head and an inner peripheral surface of the hole of the object to be measured from the ranging device, (2) acquires a distance O between the second measuring head and an outer peripheral surface of the object to be measured from the ranging device, and (3) calculates the thickness of the object to be measured on the basis of the distance I, the distance O, and a distance between the first and second measuring heads.
