Development and Implementation of a Skill Transfer System for a Self-Tapping Screw- Tightening Operation

摘要: Self-tapping screws have some operational peculiarities. In spite of their economical advantage that requires no prior tapping operation, a weakness self-tapping screw-tightening operations is can easily be tightened at non-right angle, thus resulting in an improper tightening strength. Increases outsourced workers reduced labor costs, but the accompanying high worker fluidity means new are more frequently introduced into factories. It necessary to train for operations, which occupies considerable portion ordinary assembly works. The purpose this study develop and implement skill transfer system operation. This (1) proposes set characteristic values evaluating quality operation develops device measure these values; (2) criteria resultant tightening; (3) training better work performance. Firstly, sets namely, torque, vertical pressure forces horizontal vibration forces, proposed. A developed. Secondly, identified, involving maximum timing, area during processing period, angle. By using such parameters, with proper aptitude identified. Thirdly, consists screwdriver feedback information about results Finally, validity experimentally verified operators actual workers.
