摘要/Abstract

摘要：

针对金刚石绳锯的长锯切弧区及大断续比的加工特点,参考已有的大切深断续磨削温度模型的研究成果,利用移动热源法,建立了金刚石绳锯加工弧区的温度场理论模型。推导出在均布热源和三角形热源作用下的绳锯加工弧区理论温度场。研究结果表明:金刚石绳锯加工弧区内温度呈波动上升趋势;随绳锯转速和进给速度增大,锯切弧区的温度呈上升趋势;断续比值增大,锯切弧区温度随之上升。

Abstract:

Based on the research results of a temperature theoretical model of deep grinding with intermittent wheel, the sawing temperature theoretical model of diamond wire was established with the moving heat source method for the processing characteristics of diamond wire sawing of long sawing arc zone and large intermittent ratio. The temperature fields were derived with uniform heat source and triangle heat source. The results show that the temperature in the sawing arc with a diamond wire increases with vibration. The temperature increases with the sawing speed and the feeding speed. The temperature increases with the increasing of intermittent ratio.

Key words: diamond wire sawing, sawing temperature, theoretical model, moving heat source
