【Abstract】 Applying the principles of differential geometry and kinematics,the relationship between the tool and flute surface has been established,and the mathematical model of micro-drill flute has been formulated based on the basic engagement condition between the generating tool surface and generated flute surface.By the analysis of microdrill flute machining,one of CAD method is proposed. The flute CAD system of micro-drill has been developed.with this system,the flute profile of micro-drill can be obtained converiently under the conditions of tool cross section.更多还原
