摘要
采用钻削加工方式,选择硬质合金刀具,应用正交试验方法分析了钼合金钻削过程中各个钻削参数对钻削力的影响程度,研究了钻削过程中钻削参数与钻削力、钻削力矩之间的变化关系。对钻削试验所得数据进行线性回归分析,通过回归计算得到钻削力与其因素参数之间的数学公式,并对校正R2拟合判定系数、累积概率图和残差图进行分析检验回归模型。结果表明:回归分析所得的钻削力、钻削力矩回归方程较好地拟合了钻削试验获得的数据,钻削力与钻削参数的变化规律近似符合与各影响参数的指数关系。
By drilling molybdenum alloys with cemented carbide tools and the orthogonal test method,the influence of each drilling parameter on the drilling force is analyzed,and the relationship between drilling parameters and the drilling force and torque is also investigated.By regression analysis on the data obtained from the drilling experiment,and the empirical mathematical formula of drilling force and its influencing parameters is obtained,and the regression model is tested by correcting the R2 fitting determination coefficient,cumulative probability graph and residual error graph.The results show that the drilling force and torque regression equations obtained from the analysis fit the data obtained in the experiment well,and the drilling force during the processing of the molybdenum alloy is approximately in line with the exponential relationship of each influencing parameter.
