Deep drilling operation is one of the major process that is widely used in the manufacturing industry. To make a cooling channel of hot press forming die, deep drilling is a crucial process which is the drilling depth is 10 times of the drill bit diameters itself. However, the major complications that occur is the drill bits will become wear and breaks as the drilling depth keep increasing. This will impact the efficiency of the drilling process. To overcome this drawback, Tool Condition Monitoring (TCM) was introduced to refining the quality of the drilling process by monitor the drilling operation, whether by direct or indirect monitoring, thus will improve tool life expectancy by notifying the operator to stop the machine.
