Study on Arithmetic of Milling Cutter Temperature Field Building Based on 2D Cellular Automata

切削热是铣刀片磨损和破损产生的重要原因。对铣刀片温度场研究的传统方法是有限元法。为了实现三维复杂槽型铣刀片槽型优化中能直接利用分析得到的数据进行自组织动态设计,文中结合切削温度试验,利用元胞自动机理论对铣刀片温度场进行研究,建立了二维波形刃铣刀片温度场算法系统,得出切削中各点的温度场,为刀片槽型重构奠定基础。

Cutting heat is the main reason of wears and damages of milling insert. The traditional method for studying on temperature field of milling insert is FEM. In order to use the data directly, which obtained by analysis, for self-organization dynamic design on groove optimization in milling insert with three dimensional complex groove, the paper used the cellular automata theory to study on temperature field of milling insert, associated with cutting temperature experiment. Then established the algorithmic system of temperature field for two-dimensional wave insert and got everypoint temperature field in milling process. It made the foundation for milling insert＇s groove construction.
