Design of Jig for a Four-jaw Independent Chuck Lathe Machine

Abstract

This study discusses the process of designing a jig for a four-jaw independent chuck on a lathe machine. The aim of this study is to provide a design of jig that can be used in the teaching and learning process for Mechanical Workshop Practice 2 course for students of Diploma in Mechanical Engineering program at the Department of Mechanical Engineering, Politeknik Mukah, Sarawak. The main factor in the development of the jig is to simplify the student’s task and reduce the time taken for setting up the workpiece on the lathe machine. The process of designing this jig involves several stages, namely the study of the surface, angle and direction and the details design using CATIA software. By using the jig, the process of setting up the workpiece on the lathe machine is expected to be easier and faster. In addition, students are also able to understand the function and importance of tool angle. Indirectly, the level of students’ understanding of the process could also be improved.
