Description

technical field [0001] The invention relates to machining technology, and relates to wire turning and testing thereof, in particular to a method and device for testing wire cutting force. Background technique [0002] In machining, the stiffness of rotary parts is determined by the diameter and length, where L is the length and d is the diameter. When the wire to be processed is L / d>>10, it is necessary to control the cutting and processing of the wire more precisely to ensure the processing accuracy and quality requirements in wire processing. For wire metal, the clamping method of the wire also has a certain influence on the measurement of cutting force. The main factor affecting the processing quality is the real-time detection of cutting force. Real-time cutting force values ​​are required for research on metal refinement of cutting wire or wire processing control and on-line detection. To measure the cutting force of wire, it is first necessary to determine the...
