MATHEMATICAL MODEL OF MILLING TEMPERATURE AND TEMPERATURE FIELD ANALYSIS FOR THREE-DIMEN-SIONAL COMPLEX GROOVE MILLING INSERT

摘要

The mathematical model on the temperature of the waved-edge is constructed according to Jaeger's theory of moving solid and based on the used temperature model of the flat insert. It is possible to forecast the milling temperature through programming. The comparable experiments have been done between the two new three-dimension groove inserts (waved-edge insert, great edge insert) and flat fake insert. The theoretic forecast is in good agreement with the experimental result.According to the cutting conditions, the boundary condition of finite element analysis on cutting temperature field is established, and the three- dimensional temperature fields of inserts with grooves are analyzed by FEM, so as to offer a reference basis for the design and optimization of insert grooves.
