As a precise machining process

traditional lapping cannot meet the demand of highly socialized mass production.For high efficiency and high quality

lapping technology of NC to lapping motion parameters as core is researched for hypoid gear.Elastic and grating devices are additionally set up for tooth contact on rolling.With its actual measurement and theoretical deduction

the accurate lapping motion parameters can be obtained by calling MatLab calculation program under VC++

and the automatic lapping and motion control programs are designed

which takes an important step in precise control for lapping on tooth surface and development of NC of lapping tooth machine for hypoid gears.
