This paper analyzes preventive maintenance scheduling of bottleneck equipment in a line concept of a wafer manufacturing line that has buffer in between equipment. After the start-up of the manufacturing, it has implemented time based maintenance and counter based maintenance without any fix sequence. The maintenance team will select in advance the date and time of the actual preventive maintenance to be perform and making sure all resources are planned. Then maintenance team implemented a Preventive Maintenance sequence which gives the lowest impact in production loss without sacrificing equipment’s quality and safety. This Preventive Maintenance Scheduling sequence is the best suitable method for manufacturing equipment that has buffer in between equipment which is arranged in a line concept. It has also been tested and proven in a wafer manufacturing industry.

Cutting Processes

Milling is widely used metal removal process in manufacturing industry that involves generation of high cutting forces and temperature. Lubricants become important to reduce the cutting force and temperature for better machining processes and performances. Conventional cutting fluid has some limitations. The applications of conventional cutting fluid create some techno-environmental problems like environmental pollution, biological problems to operators and water pollution. Application of solid lubricant in milling has proved to be a feasible alternative to the conventional cutting fluids. The present work investigates the effect of boric acid as solid lubricant towards machining performances such as tool wear and surface roughness. The results indicate that boric acid can improve the cutting processes and performance compared to conventional cutting fluid.
