Abstract

Considering that drilling constitutes about 40% of all metal cutting operations, the improvement on the drilling process would result into faster productivity. Aluminum alloy is mentioned by researchers that the speed at which aluminum being drilled has been increasing through the years. Since aluminum is a soft material, therefore it is easy to machine and can be aggressively drilled. Aggressive Drilling (AD) is based on High Speed Machining (HSM)concept, and the speed applied on AD is much higher than the conventional machining speed. Currently, aluminum is mostly used by automotive and aerospace industries because of its light weight and good corrosion resistance. This project investigates the implementation of the AD on aluminum by an automotive organization in Malaysia. Case study method is used to investigate the potential benefits and challenges associated with the AD implementation. Recogniz.ed AD method would be suggested and would benefit to others. From the case study, it is found that there is a lack of awareness on the potential of the AD on aluminum.Although the HSM concept is practiced, it is not being applied at the very high speed region. The improvement process has been carried out but it is not been focused on the drilling process. It is recommended that for futme research on the awareness of the potential benefits of AD on aluminum to the industries. Collaborative work between university and industry also can be carried out especially on the development of AD controlled parameters.
