Cutting force measurement system auxiliary device design
: cutting process will have the cutting force participation, and cutting force is decided to a condition of the most indispensable parts in finished from blank. The cutting force directly affects the machining quality of parts machining process ,control the cutting force can reduce the reject rate and failure rate. In the premise of not affecting the machining quality, increase the cutting force can improve the machining efficiency of the parts, reduce the processing cost of parts. But the cutting force measurement is not easy, in the machining process ,the cutting force is changing, is dynamic, so the design force measuring system will be our task. The device is usually used for force measurement strain gauge, the size characteristic of the strain gauge we can measure the cutting force. According to the difference of location and number of strain gauge placed on the measured cutting force, size and accuracy will vary. Auxiliary device for measuring cutting force so that much attention.
Key Words：Cutting force; strain gauge, parts, auxiliary device
