Diamond fly-cutter milling method for micro grooves in ferrous metal material base

Abstract

The invention discloses a diamond fly-cutter milling method for micro grooves in a ferrous metal material base. The method comprises the steps that a cutter bar of a diamond fly-cutter is connected with a two-dimensional ultrasonic elliptical vibration transducer, and the diamond fly-cutter is fixed to the end of the cutter bar; the elliptical vibration transducer is fixed to a spindle of a diamond fly-cutter milling machine; a sine-wave voltage is exerted on the elliptical vibration transducer, the diamond fly-cutter conducts ultrasonic elliptical vibration along with two-dimensional elliptical vibration generated by the elliptical vibration transducer, meanwhile, the diamond fly-cutter conducts axial and radial feeding milling motion on the ferrous metal material base along with the spindle of the milling machine, and therefore ultrasonic elliptical vibration and diamond fly-cutter milling are realized. Through the method, sharp diffusive wear of the diamond fly-cutter in the process of milling the micro grooves in the ferrous metal material base can be effectively restrained, generation of burrs at the edges of the micro grooves is restrained, the morphological precision of the micro grooves is improved, and diamond fly-cutter precise milling of the micro grooves is realized.

Description

technical field [0001] The invention relates to a method for processing micro-grooves on a black metal material substrate, which belongs to the technical field of mechanical processing, in particular to a diamond flying cutter milling method for micro-grooves on a black metal material substrate. Background technique [0002] For micro-grooves of different shapes and sizes on the same substrate, it is difficult to meet the requirements by grinding. After searching the existing technical literature, it was found that Jiao Yangyang et al. wrote an article "Research on CAD / CAM System for Micro-V Groove Machining by Flying Tool" in "Combined Machine Tool and Automatic Processing Technology" No. 6, 2014. For the ultra-precision machining of grooves, an integrated system platform has been developed from groove design, data conversion, part modeling, processing simulation and cutting parameter optimization. Using diamond flying tools can process micro-grooves of different shapes and...

AI Technical Summary

Problems solved by technology

However, for processing micro-grooves on black metal substrates, diamond flying cutter milling is used. Due to the sharp diffusion and wear between diamond flying cutters and black metal materials, diamond flying cutters are used for microgrooves on black metal substrates. Groove precision milling is difficult to achieve. At the same time, there is a problem that burrs are generated at the edge of the micro-groove after diamond flying cutter milling, and the micro-groove shape accuracy is reduced during subsequent deburring.
