Abstract
Tool wear and hole accuracy are the main factors observed by the manufacturer to reduce the cost in the aerospace industry. This study was carried out to find the optimum parameter that will give a good impact on the force and tool wear. This research executed the variant in the cutting parameter used such as spindle speed and feed rate while maintaining the number of drilled holes. This research had been conducted with data collection on the range of the cutting parameter. The design of jig is required to guide the cutting tool and covered dynamometer during machining. It will help to achieve a reliable result of force and protect the safety dynamometer due to it is highly cost. Tribology test had been run to identify the properties of CFRP composite such as wear rate and frictional force. The lowest thrust force that produces during the micro-drilling process will reduce delamination on entry and exit of holes. The significant parameter had been defined by Analysis of variance (ANOVA). Taguchi Method was used to screening and eliminate the parameter that not significant to identify the lowest force. The optimize parameter for this design are spindle speed 12 000 rpm and feed rate 0.01 mm/rev. Finally, 2-Level Factorial Method has been applied to optimize the parameter of the experiment. This design was optimizing the parameter which is spindle speed 12000 rpm and feed rate 0.01mm/rev.
