Development of Mechanical Actuator for Deep-Hole Measurement System

Abstract

This paper presents a new type of mechanical actuator which is used to help in measuring deep holes that carry up to a load of 26kg during measurement. Often the measurement probe‘s attitude is misaligned due to acting force on it. Actuator prevents or controls the misalignment of such probe during measurement. In this research, the complete measurement system consists of a servo motor, a laser diode, a laser interferometer, an optical system as well as the integrated computer system. The main purpose of this research is to develop the new type of actuator which can control the attitude (position and inclination) of a measurement probe. The experimental results show that it is possible to carry mechanically the loads up to 26kg of the measurement probe during measurement of deep-holes. In this paper, the developed actuator’s mechanical function and its performance have been discussed with the experimental results.
