Prosiding Seminar Hasil Penelitian dan Pengabdian Masyarakat
Abstract
The CNC machine Emco VMC-200 in CNC laboratory of Jurusan Teknik Mesin Politeknik Negeri Semarang has a limited working area of 200 mm x 200 mm and the tool movement on the Z-axis, object movement on the X-axis and Y-axis. An increase in the working area of the machine has been made to 400 mm x 200 m in previous studies. The purpose of this research is to analyze and modify the workpiece clamping vise so that there is an increase in the ability to change the rotation angle of the workpiece with respect to the Y-axis, X-axis, and Z-axis. This research will apply Sighley's Mencahnical Engineering Design method which consists of the following stages: identification of need, definition of problem, synthesis, analysis & optimization, evaluation, and presentation. The results of this study obtained that the use of the angle vise used can overcome the limitations of the machine for gripping the workpiece and help to be able to work on the workpiece with a change in angle or the workpiece has a certain angle of inclination. Rotation capability on X-axis and Y-axis is 600 and Z-axis can rotate to 3600
