陶瓷表面激光加热温度场的分析

Laser Heating on Ceramics Surface

激光加热辅助切削是解决陶瓷这种硬淬材料切削加工的有效方法．本文主要根据激光加热辅助切削的特点，建立激光加热的数学模型，采用解析法，从理论上分析了激光对陶瓷加热时温度场的分布规律，计算分析了对四种陶瓷材料进行激光加热时，热影响区深度和温度的变化规律，为陶瓷激光加热辅助切削奠定了理论基础．

For high hardness and high temperature and corrsion resistance, ceramics has become one of three im-POrtant engineering materials. However, it is difficult to cut it with common cutting methods and therefore, ceramics are not widely used in industries. Laser heating assisted cutting is an effective of for cutting ceramics. A laser heat- ing math model is proposed to calculate the temperature field while the ceramics is heated with laser.
