Research And Development Of Milling Insert With 3D Complex Groove

This thesis comes to the conclusions that are parts of research achievements of an important technology project,which belongs to Heilongjiang province and is"product and research of large-scale complicacy parts with modern knife series". Milling tool optimizes its groove to make machinability better. People worked on research of 3D groove inserts for many years and got lots of important achievements. With continuously development of industries,new requirements of tool's machinability are proposed. This paper proceed system research, theoretical research and development design of products. The main contents of this paper are following:1. Using different material,groove inserts to cut different workpiece and contrast research of milling experiments with cutting force. The contrast research of milling experiments is proceed using different experiment's parameters with plane milling insert, 3D groove wave milling insert,Ultra-fine grain,4030,4050. Contrast research of these tools'life is made by milling experiments in HEC.2. Developing 2D and 3D groove of heavy cutting inserts. Structure and groove of heavy cutting insert for cutting large-scale container are designed. Theoretical analysis is made for grinding planning of tool's groove. Calculating soft is programmed using VC. After groove width and forth angle in heavy cutting tools are completed,roll of grinding wheel will be got when applicating the program.3. Through research of cylinder spiral milling insert , we get space geometrical model of spiral blade and proceed surface waviness error analysis of spiral and straight blade. According to cutting theory, we proceed optimum design of cylinder spiral.
