摘要/Abstract

摘要： 在大批量干切削加工中，通常使用压缩空气对切削区进行冷却。为解决干切削机床的热平衡问题，提出一种干切削机床压缩空气冷却系统热力学模型及热平衡控制方法。建立了喷嘴出口处压缩空气的温度、速度及质量流量与压缩空气冷却系统及环境相关参量的热力学关系模型，进一步建立了干切削机床热平衡模型，然后以压缩空气的温度、质量流量及供给时间为调控变量，对干切削机床的热平衡调控方法进行了研究。以高速干切滚齿机床为例进行了验证，结果表明，该方法可有效保证在持续加工时干切削机床加工内区域的温度变化在可控范围内。

Abstract: In dry cutting mass production, the cold compressed air is used to cool the cutting zone. A thermodynamic model of air cooling system and a heat balance control method of dry cutting machine tool are presented, in order to solve the heat balance problem of dry cutting machine tool. The relation between thermodynamics parameters of compressed air at nozzle exit and parameters of air cooling system is analysed. Furthermore, the heat balance model of dry cutting machine tool is established. Based on it, a heat balance control method of dry cutting machine tool, which is realized with regulating the thermodynamics parameters and supply duration of compressed air, is proposed. Experiment on dry hobbing machine tool, shows that the proposed method can makes temperature of machine tool components fluctuated in an acceptable range.

Key words: air cooling system, dry cutting, thermal balance control, thermodynamic model
