Problems solved by technology

However, there are still some bottlenecks in this method: (1) It is difficult to greatly improve the processing efficiency: due to the high hardness and brittleness of the material, the limited tool wear resistance and toughness, the applicable depth of cut and feed rate are too small; (2 ) Severe tool wear: when processing superhard materials, the tool wear is serious, the tool life is short, and the accuracy is improved by relying on compensation, the process is complicated, and the processing cost is high, which limits its wide application

Embodiment 1

[0039] see figure 1 , the laser prefabricated micro-texture-assisted ultrasonic milling processing system provided by the present invention includes a multi-axis linkage laser processing system 1 and a multi-axis linkage ultrasonic-assisted milling processing system 2, wherein the multi-axis linkage laser processing system 1 is used for the material to be processed Laser pretreatment is performed to form a prefabricated micro-texture on the material to be processed, and the multi-axis linkage ultrasonic-assisted milling system 2 is used to mill the material to be processed after laser pretreatment to form the desired product. The prefabricated micro-textures include vertical micro-groove arrays, chute arrays with a certain angle to the feed direction, grid arrays, circular hole arrays, curved groove arrays, and horizontal micro-groove arrays (see Figure 5A-5F for details).

[0040] The multi-axis linkage laser processing system 1 includes a first motion control unit 11, three ...

Embodiment 2

[0053] The functional structure of the laser prefabricated microtexture assisted ultrasonic milling processing system in this embodiment is basically the same as that of the laser prefabricated microtexture assisted ultrasonic milling processing system in Embodiment 1. The difference is that the multi-axis linkage laser processing system 1 and the multi-axis linkage ultrasonic-assisted milling processing system 2 in this embodiment are integrated online to realize dynamic synchronous large-scale matching processing, and the degree of freedom of rotation of the material to be processed relative to the ultrasonic tool is determined by The swing of the ultrasonic-assisted milling table 24 of the multi-axis linkage ultrasonic-assisted milling processing system 2 is realized, and the spatial attitude of the material to be processed after laser pretreatment relative to the laser beam is realized by the swing of the laser beam.

[0054] In the working state, the laser beam of the mult...

Embodiment 3

[0057] The functional structure of the laser prefabricated microtexture assisted ultrasonic milling processing system in this embodiment is basically the same as that of the laser prefabricated microtexture assisted ultrasonic milling processing system in Embodiment 2. The difference is that the degree of freedom of rotation of the material to be processed relative to the ultrasonic tool after laser pretreatment is realized by the swing of the spindle 25 of the multi-axis linkage ultrasonic-assisted milling system 2, and the spatial attitude of the material to be processed relative to the laser beam is determined by the laser beam swing implementation.

[0058] Compared with the structure shown in Embodiment 2, this structure is more suitable for processing large-scale structural workpieces.

Abstract

The invention provides an auxiliary ultrasound milling technological method for laser micro-texture prefabricating. The technological method comprises a laser pretreatment step and an ultrasound auxiliary milling step. The laser pretreatment step comprises the sub-steps that a position parameter of a to-be-machined material is adjusted, so that the position parameter of the to-be-machined material is in accordance with a first predetermined position parameter; and a laser beam is generated, and the spatial posture, corresponding to the to-be-machined material, of the laser beam is adjusted. The ultrasound auxiliary milling step comprises the sub-steps that the position parameter of the to-be-machined materials subjected to laser pretreatment is adjusted, so that the position parameter of the to-be-machined material is in accordance with a second predetermined position parameter; ultrasound vibration of an ultrasound cutter assembly is controlled; the ultrasound cutter assembly is rotated, and the rotation freedom degree, corresponding to the to-be-machined material subjected to laser pretreatment, of the ultrasound cutter assembly is adjusted; and the position relation between the ultrasound cutter assembly and the to-be-machined material subjected to laser pretreatment in the X direction, the Y direction and the Z direction is changed. The invention further relates to an auxiliary ultrasound milling machining system for laser micro-texture prefabricating.

Description

technical field [0001] The invention relates to the technical field of special processing, in particular to a laser prefabricated micro-texture assisted ultrasonic milling process method and a processing system. Background technique [0002] With the development of manufacturing technology, hard and brittle materials have shown broad application prospects in the fields of aviation, aerospace, molds, optics, and semiconductors. Engineering ceramics are typical hard and brittle materials with excellent properties such as high hardness, high temperature resistance, stable chemical properties, and good insulation properties. They are widely used in aerospace, optics, electronics, energy, and national defense industries. Conventional cutting of hard and brittle material components is very difficult, and is usually obtained through ultra-precision grinding, polishing and ultra-precision grinding. However, this method takes a long time to process and has high processing costs. It i...
