Time Optimization Implementation in Conventional Lathe Machining Operations
A study of time optimization in conventional lathe machining operations of the higher technical learning institutions in Malaysia was performed. This is to ensure that the students may complete a project within 30 contact hours. Based on previous experiences, almost 50% projects may not be able to completed on time. Time optimization is a process to increase productivity of machinists while reducing wastes. Three objectives were identified in this study, focused to identify time waste, simulate and suggest methods of the improvement. A few quantitative methods to identify the problem, i.e. the experimenting samples method, simulate and verification were used. As a result, time taken for machinist’s movement, inspections and storage were improved and this contributes to the highest improvement. Hence, the idle time has been minimized. The enhancement of standard operating procedure, audio-visual learning and layout design in the study played significant roles in completing the study. The movement and storage times were suggested for enhancement to reduces the issue of productivity.
