Description
Technical field
The present invention relates to a kind of ultrasonic cutting methods of honeycomb core deep gouge structure, belong to comb core material mechanical processing neck
Domain.
Background technology
Comb core material has the characteristics that specific stiffness and specific strength height, performance are stable and light-weight, is widely used in navigating
Empty space flight and rail vehicle transportation field.In order to meet different use demands, comb core material is usually processed to various
Shape.The mechanical processing of cellular material crushes milling cutter in process mostly using high-speed milling mode using dedicated honeycomb core
Carry out the broken removal of material.But during comb core material high-speed milling, there are honeycomb core material deformation greatly, the bee after processing
The problems such as nest quality is difficult to ensure that stock-removing efficiency is relatively low, and tool wear is serious, and environment dust pollution is serious.Ultrasonic cutting honeycomb
For core as a kind of novel processing technology, basic principle is to apply ultrasonic vibration on cutting tool, while cutting, is utilized
Ultrasonic energy opens rapidly material.Ultrasonic cutting has that cutting force is small, material deformation is small, and the material surface finishing after processing is hairless
The advantages that thorn, overcomes the deficiency of high-speed milling, can realize the high-quality and high-efficiency processing of honeycomb core material.
Honeycomb core deep gouge is the quasi-representative difficulty processing structure in honeycomb core working angles.Using traditional high-speed milling side
Method while workpiece is cut in cutter at high speeds milling, is usually associated with the strong friction and squeezing action of cutter and material, so as to
Honeycomb core material burr and conquassation defect are caused, influences processing quality and processing efficiency.Compared with high-speed milling, ultrasonic cutting has
Significant advantage, but for specific deep gouge structure, due to its processing mechanism and material removing method difference, ultrasonic cutting
Technique has bigger difference with traditional milling at a high speed, need it is more supersonic cutting tool cooperation could realize deep gouge structure plus
Work.In order to effectively avoid the manufacturing deficiency of honeycomb core deep gouge structure, meet the high-quality and high-efficiency processing of honeycomb core material deep gouge structure
It is required that, it would be highly desirable to propose a kind of process being suitble to the processing of honeycomb core deep gouge structure.
