【摘要】：为了研究硬脆材料微铣削的温度场,基于微铣削石英玻璃,建立了微铣削热源分布模型。该模型将热源形状假设为半圆形,并在该热源形状下对矩形热源、三角形热源进行了有限元分析,通过微铣削石英玻璃试验将测量的温度数据与有限元结果做了对比分析。结果表明:矩形热源模型比三角形热源模型更加接近实际的微铣削区热源分布情况,加工参数中的主轴转速对微铣削温度影响程度最大,主轴倾角次之,切削深度和进给速度则相差不大。
[Abstract]:In order to study the temperature field of the micro milling of hard and brittle materials, based on the micro milling of quartz glass, the heat source distribution model of micro milling is established. The model assumes the shape of the heat source as a semicircle, and the finite element analysis is carried out on the rectangular heat source and the triangle heat source under the shape of the heat source, and the temperature data and the measured temperature data are measured by the micromilling of the quartz glass. The result shows that the rectangular heat source model is more close to the actual heat source distribution in the micro milling area than the triangle heat source model. The spindle speed in the processing parameters has the greatest influence on the micro milling temperature, the main axis angle is the second, the cutting depth and the feed speed are very different.
