Drilling force measurement system auxiliary device design
Abstract: Size of cutting force in the process of cutting will directly affect the quality of cutting heat generation, processing surface, the precision work piece machining, tool wear Because of the complexity and uncertainty of the process conditions, cutting force calculation values with the actual values of the deviation, it is best to use dynamometer measurements in the field. Direct measurement of cutting forces in order to be able to size, there have been many types of dynamometer, most of them used to measure static or quasi-static force. With the development of precision machining technology, measurement of dynamic cutting force dynamometer became a research and development objectives. Drilling force on the secondary device is covered, bases and composed of piezoelectric quartz crystal in the middle. This drilling dynamometer structure characteristics, can improve the sensitivity of the dynamometer, and automatic compensation of cutting heat causing the error. Piezoelectric quartz crystal placed to force delivery and loading, is a key part of the dynamometer.
