二维元胞自动机的温度场数学模型的建立

Established Model of Temperature Field Based on 2D Cellular Automata

铣刀片的材料主要采用硬质合金和金属陶瓷等脆性材料,在切削过程中产生的热应力造成热疲劳损伤是刀具破损的主要原因,因此,研究切削过程中产生的温度,以及在切削过程中的温度变化对于揭示刀具破损磨损是十分重要的内容,该文以二维元胞自动机思想为基础,建立铣刀片的温度场模型,根据此模型研究温度在铣刀片内部的变化规律.

Insert material mainly made of hard alloy and metal brittle materials such as ceramics,produced in the cutting process of the thermal stress caused by thermal fatigue damage is the main reason of the tool breakage,so the research on the cutting process of temperature and temperature evolution in the process of cutting tool breakage and wearing to reveal is the main content. In this paper,on the basis of 2D cel-lular automata thought,the model of temperature field of milling insert is established according to the study on the changing law of temperature in this model of milling insert inside.
