摘要
建立了以机床功率、最大容许切削力、工件轴线许用挠度、刀具耐用度等作为约束条件,以最大金属切除率和最小工件表面粗糙度作为优化指标的多目标最优化模型;提出了一种新的优化方法,即利用VC++创建用户界面,运用LINGO软件在后台进行求解计算。DEFORM-3D有限元模拟结果与分析证明:采用优化后的切削参数可以显著降低刀具所受切削应力并且减少刀具磨损量。
By using the machine power, the maximum allowable cutting force, the allowable deflection of the workpiece axis and the tool life as the constraints, and using the maximum metal removal rate and minimum surface roughness as the optimization indexes, an multi-objective optimization model was established. A new optimization method was presented, in which the VC ＋ ＋ was used to create the user interface and the software LINGO was used to calculate in background. The results of simulating and analyzing the cutting process using DEFORM- 3D showed that the use of the optimized cutting parameters could significantly reduce the cutting stress and tool wear.
