英文摘要： A new high effective precision abrasive jet technology which applied recombination energy including mechanical,electrical field as well as chemical action to difficult-to-cut metallic matrix materials surface is proposed. The principal of this technology is that the workpiece surface material is removed by the action of compound energy field including mechanical,electrical and chemical effect and different energy can be strengthened reciprocally. So the machining efficiency can be increased greatly while high quality surface can be achieved. In this project, firstly, on the basis of investigating the mechanism of multifield coupling action and the multiphase flow as well as different energy simultaneous to material removal,the material removal mechanism for this technology can be presented. Secondly, an experimental equipment will be developed based on the mechanism studying above. And then the mathematic model of material removal characteristic for this technology and the surface integrity as well as machining control technology will be studied.The machining process for this technology will be researched on this experimental equipment. At last, a new high effective precision machining method to difficult-to-cut materials can be obtained. The achievement of this project can be widely applied to machine the diffi
