MATHEMATICAL MODEL AND THE CAD SYSTEM OF THE GRINDING WHEEL FOR DRILL'S FLUTE

摘要

Applying the principles of differential geometry and kinematics, the mathematical model solving the grinding wheel axial cross-section by the given drill's flute radial cross-section has been formulated on the basic engagement condition between the generating flute and the generated grinding wheel. The mathematical model of the flute radial cross-section with three arcs has been established. The CAD system solving the grinding wheel axial cross-section has been developed. With the system, the grinding wheel axial cross-section can be obtained conveniently under the condition of the flute radial cross-section with three pieces of arc.
