PROBLEM TO BE SOLVED: To provide a measuring system which realizes the shortest measuring time and high operational reliability, without using any linear sensor being of expensive accurate length measuring devices. SOLUTION: A mass production-use apparatus for dimensional inspection of a machined part is provided, which uses an electric servo cylinder composed of a rotational-linear motion converting mechanism employing a screw and an electric servomotor capable of freely controlling a cylinder speed in a measurement operation, does not use any external sensor for the measurement, uses the first time machined part as a dimension work master and leverages a "recursive positioning" performance capable of realizing a high precision, thereby clearing disadvantages of conventional apparatuses.
