Abstract
A machining system that can be operated at a predetermined cutting force by changing the feed rate based on cutting force signals measured by a piezoelectric type of dynamometer has been developed. And then, the basic performances of the newly developed system have been confirmed through evaluation tests. In addition, the possibility of CFRP (Carbon Fiber Reinforced Plastic) laminates drilling with the developed machining system has been investigated. As a result of the drilling tests with drills, the newly developed system can machine through-holes without significant delamination on CFRP laminates. It is confirmed that the developed machining system can optimize drilling process by controlling the feed rate based on the cutting force signals through the tests.
