Embodiment

[0032] The concrete steps of the diamond flying cutter milling process method of micro-groove on the black metal material substrate of the present invention are as follows: (1) diamond flying cutter cutter bar is connected to each other with two-dimensional ultrasonic elliptical vibration transducer by screw thread; (2) has A sine wave voltage of 80 volts is applied to the two-dimensional ultrasonic elliptical vibration transducer at the same time, and the two-dimensional ultrasonic elliptical vibration transducer generates ultrasonic vibrations in two directions perpendicular to each other, and synthesizes ultrasonic elliptical vibrations at its output; (3 ) The diamond flying knife holder is designed into a cylindrical stepped shape, so that the two-dimensional elliptical vibration generated by the ultrasonic elliptical vibration transducer can be further increased, reaching a major axis: 10 μm, a minor axis: 5 μm, an included angle: 45°, and a resonance frequency: Ultrasonic...

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...
