STUDY ON 3D TEMPERATURE DISTRIBUTION OF MILLING INSERT WITH COMPLEX GROOVE

摘要

About 90% energy generated in the milling process is transferred to heat which makes the temperature to increase. The temperature increase has a correlative relationship with the milling mechanism and milling parameters. The severe temperature increase results in the fracture of milling insert during milling process and reduces the life of the tool. Experiments of milling temperature measurement were conducted to study the temperature field in milling. The heating density function on the tool surface was established. The temperature profile and distribution were shown. A parametric model was established to represent the milling insert with 3D complex groove. Based on a finite element analysis, the temperature field on the milling insert was evaluated and the boundary condition was established by using the heating density function. The study provides a reference for the development and optimization of complex grooves of milling inserts.
