切削参数对子午线轮胎模具侧板切削比能及表面粗糙度的影响研究

以子午线轮胎模具侧板为研究对象进行铣削试验,着重研究主轴转速、每齿进给量、切削深度对轮胎模具侧板切削比能、材料去除率和表面粗糙度的影响规律。分析试验结果可知:切削比能随着切削参数的增大而减小,说明适当增大切削参数可以提高切削效率并节约能量;表面粗糙度随主轴转速增大呈先增大后减小的趋势,随切削深度和每齿进给量的增加而增大。结果表明:提高主轴转速既有利于降低切削比能(节能)也有利于改善表面粗糙度,增大每齿进给量和切削深度会降低切削比能但会恶化表面质量。因此,为同时达到高效节能和良好表面质量的要求,应尽量提高主轴转速。

Study on the Influence of Cutting Parameters on Specific Cutting Energy and Surface Roughness of Radial Tire Mould Side Plate

The milling test was carried out on the side plate of radial tire mould. The effects of spindle speed, feed per tooth and cutting depth on the specific cutting energy, material removal rate and surface roughness of the radial tire mould were studied. By analyzing the experimental results, it can be seen that the specific cutting energy decreases with the increase of cutting parameters, which indicates that the cutting efficiency and energy consume can be improved by increasing the cutting parameters appropriately; the surface roughness increases first and then decreases with the increase of spindle speed, and increases with the increase of cutting depth and feed per tooth. The experimental results show that by increasing the spindle speed, the specific cutting energy can be reduced and the surface roughness can be improved; with the increase of feed per tooth and cutting depth, the specific cutting energy can be decreased, but the surface quality is deteriorated. Therefore, in order to achieve the requirements of high efficiency, energy saving and good surface quality, the spindle speed should be increased as far as possible.
