摘要：
The most effective way of achieving good quality holes while drilling fibre reinforced plastics is by reducing the thrust and torque. Drilling experiments were conducted with drill points, namely standard twist drill, Zhirov-point drill, and multifacet drill, using wide range of spindle speed, and feed rate to analyse thrust force, delamination and surface roughness. At high spindle speed, cutting force is less and the special geometry improves the quality of the hole further, especially Zhirov point drill. Multifacet drill is found better as far as the delamination value is concerned.
