摘要
结合数控加工时的具体工况,利用实验数据建立参数的回归方程,用一元线性回归和正交多项式分析各参数之间的联系,并且推出了经验公式;利用回归方程数据库建立目标数学模型,对铣削过程中进行预测控制和优化处理;在受所选机床的主轴转速、进给量、进给力、切削扭矩、机床功率、工件质量等限制的基础上确立了机床约束条件,为生产现场提供参考数据。
CNC machinery manufacturing equipment rate as a measure of a country an important indicator of the level of manufacturing technology.This paper summarizes CNC milling in the modern processing equipment to the important role,Summarizes the contents and significance of regression analysis summary.Parameters using experimental data to establish the regression equation with The specific processing conditions.Explain The role of the regression equation.With a linear regression and orthogonal polynomials links among the parameters,have an Empirical formula.Regression equation established by objective mathematical model of the database.To predict the milling process control and optimization.Selected by the machine tool in the spindle speed,feed rate,feed force,cutting torque,machine power,workpiece quality limits established on the basis of machine tool constraints.
