Study on Cartesian Robot for Deep-hole Drilling with M20 Tapping

Abstract

This study employed a robot to save the manual machining time spent during manufacturing of vehicle dies. Many air holes are required to exhaust the compressed air outside during the molding process. A cartesian robot capable of machining deep holes and tapping was designed and tested considering the requirement. The robot’s shape and the kinematic structure of its axes were established during the conceptual design process. The required torque about each axis and the components of the driving parts were selected during the detail design process. Moreover, products of the company, National Instruments, were used to shorten its development time. SKD11 was chosen as the material to be processed because it is similar to the material used for die manufacturing. A test was also performed to check the thrust output according to feed rate and revolutions per minute.
