Abstract

The invention provides an ultrasonic-assisted cutting force control method, including the steps of building an ultrasonic auxiliary system, adjusting and controlling ultrasonic vibration parameters, and adjusting and controlling the cutting force; the steps of building an ultrasonic auxiliary system: building a two-dimensional elliptical ultrasonic-assisted turning system; adjusting and controlling ultrasonic vibration parameters Steps: Under the set power frequency of the ultrasonic vibration auxiliary system, use different ultrasonic vibration parameters and fixed cutting parameters to carry out ultrasonic face turning. By measuring the cutting force and observing the material removal mode and the range of cutting parameters in the elongated / brittle domain, Obtain the optimal parameters for material removal; adjust the cutting force step: fix the ultrasonic vibration parameters, use different cutting parameters, and compare the cutting force and the surface roughness of the processed workpiece to obtain the maximum cutting force under the optimal cutting parameters.

Description

technical field [0001] The present invention relates to the technical field of metal and composite material heterogeneous interface processing, in particular, to an ultrasonic-assisted cutting force control method, especially to a cutting force coordination control method in the ultrasonic-assisted processing of metal and CFRP co-cured materials, Among them, CFRP refers to carbon fiber composite materials (Carbon Fiber Reinforced Plastics). Background technique [0002] With the rapid development of advanced resin-based composite materials, the use of composite structures characterized by lightweight and high performance has become a development trend in the aerospace field. Carbon Fiber Reinforced Polymer (CFRP) has begun to replace traditional metal materials in large quantities. The flywheel of a certain type of satellite needs to use a certain metal material as a rotating part with a certain moment of inertia, while the structural support part is composed of lightweight...
