提出了三区段变参数振动钻削微孔的新工艺 ;探讨了用非线性回归求取各区段最佳振动参数的方法 ;验证了以三区段最佳振动参数做变参数时 ,用振动钻孔可以全面降低微孔加工误差的优良工艺效果 A new method of vibration drilling micro-holes with variable parameters is put forward. The method of determining the optimal vibration parameters of each section by nonlinear regression is discussed. When the optimal parameters of three sections are used as variable parameters, Drilling can fully reduce the microporous machining error of the excellent process results
