摘　　要：对微铣削过程中微铣刀刀刃受到的微铣削力进行测量,并研究其特性和变化规律.从理论角度对螺旋立铣刀的受力机理进行重点分析.借助现有的微铣削实验平台,选择典型的工件材料并设计相应的实验方法.对加工不同材料工件的刀具所受到的微铣削力进行分析,获得了微铣削力的特征和变化规律.实验结果表明:刀具受到的微铣削力随着微铣削参量的变化而变化,其变化规律与加工工件的材料性能密切相关.微铣刀刃径、每齿进给量、轴向铣削深度和材料的晶粒尺寸是引起尺寸效应的主要因素.The milling force on micro cutter blade was investigated in order to understand the characteristics and law of high-speed milling.The forced mechanism of end milling cutter was further analyzed theoretically.The experiment was carried out in a test-platform using typical materials and methods.The results show that the laws are closely linked to the physical and mechanical properties of the materials along with the changes of micro milling parameters.Moreover,the tool edge radius,feed per tooth,axial depth of cut,and grain size of the material are the main factors causing the dimensional effect.
