Research On Temperature Field Under Regular Gradient Heat Source Of Milling Insert With Complex Groove Using Cellular Automata Algorithm

摘要

Lots of cutting heat is generated in milling process, and an unsteady temperature distribution is generated, which is the radical reason of impactive fracture and sticking-welding fracture of the tool. In this paper, the Cellular Automata model of regular gradient heat source on the rake face of milling insert is built using heat transfer theory and cutting principle to analyze the temperature field generated. The boundary condition of the insert is established and the unsteady temperature field of the insert is obtained using the Cellular Automata algorithm, which can be a basis for the direct reconstruction of the insert.
