针对汽车功能主模型检具中的车门薄壁模拟块高速铣削工况,提出了四因素四水平的正交试验方案,运用多元线性回归方法建立了螺旋刃球头铣刀的铣削力经验指数模型。通过正交试验表,初步分析了各铣削参数对铣削力的影响,并采取进一步试验,验证了模型的精度,给出了初步优化参数。铣削力经验指数模型的建立在为加工现场提供快速铣削力计算方法的同时,也为同类薄壁件高速铣削加工有限元模拟和变形控制方案的研究提供可靠的力边界条件。

Reviewed several ball-end milling force calculations ,and an orthogonal experiment scheme was adopted to investigate ball-end milling force for specific conditions in precision ball-end milling.Orthogonal regression analysis method was used to build the exponential model of ball-end milling force ,analysis of the influence of the milling parameters on milling force was given through the orthogonal experiment intuitive analysis table ,and the optimized parameters were proposed preliminary .At last milling experiment was applied to test and verify the accuracy of formula .All these provide a rapid calculation of milling force for workers and lay a firm foundation for the next study of thin-walled workpiece FEA and deformation control scheme .
