A computer program for simulating a gear shaving process has been developed. In the simulation, penetration of the land edge of the shaving cutter into the work tooth flank ; i. e. , depth of cut, is calculated over the whole tooth flank, and a stock removal is estimated to evaluate the shaved tooth form of the work gear. The estimation of the stock removal is based on a given relationship between depth of cut and stock removal. In the previous method, the depth of cut is evaluated from an elastic contact approach between cutter and work tooth flanks, thus a very large calculation time is required. In the present paper, a geometrical depth of cut is adopted for the evaluation of the stock removal. The geometrical depth of cut can be calculated using the mechanismic requirement. Hence, the calculation time can be largely reduced. The relationship between depth of cut and stock removal is carefully selected to obtain an agreement between the measured and calculated tooth forms of shaved gears.
