Abstract

The invention provides an ultrasonic auxiliary cutting force control method. The ultrasonic auxiliary cutting force control method comprises the steps of building an ultrasonic auxiliary system, adjusting and controlling ultrasonic vibration parameters and adjusting and controlling cutting force. The step of building the ultrasonic auxiliary system comprises: building a two-dimensional ellipticalultrasonic auxiliary turning system; the step of adjusting and controlling the ultrasonic vibration parameters comprises: carrying out ultrasonic end face turning with different ultrasonic vibration parameters and fixed cutting parameters under the set power supply frequency of the ultrasonic vibration auxiliary system, and obtaining an optimal material removal parameter by measuring the cutting force, observing a material removal mode and the extension / brittleness region cutting parameter range; and the step of adjusting and controlling the cutting force comprises: fixing the ultrasonic vibration parameters, adopting the different cutting parameters, and obtaining the maximum cutting force under the optimal cutting parameters through numerical comparison of the cutting force and the machined workpiece surface roughness.

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...
