摘要
针对超高速切削铜材料电极产生的噪声问题,通过用INV3018G型噪声仪采用多因素正交试验方法进行数控切削削噪声实验,采用大数据分析的方法,对实验数据进行极差和方差分析,得出各因素对切削噪声的贡献大小依次为装夹高度、主轴转速、进给速度和背吃刀量,显著性大小依次为装夹高度、主轴转速、进给速度和背吃刀量,其中装夹高度对环境噪声的影响最大。通过数控加工电极切削参数的合理选择,可达到降低工作环境噪声的目的。
Aiming at the noise problem caused by ultra-high-speed cutting of copper-material electrodes,the numerical control cutting noise experiments are carried out by using the INV3018G noise meter and the multi-factor orthogonal test method.Using the method of large data analysis,the extreme analysis and the variance analysis are done for the experimental data.The contributions of various factors to the cutting noise are analyzed.The clamping height has the largest contribution to the cutting noise,and followed by spindle speed,feed speed and back-feeding amount.Of them the clamping height has the largest effect on the environment noise.Through a reasonable selection of the cutting parameters for the CNC machining of the electrode,the noise of the working environment can be appropriately reduced.
