Development of an algorithm for calculating the number of regrindings for a shaver with the continuous spiral cutting edge

There is a construction of tool of a worm type (shaver) at that a cutting wedge has the structurally performed clearance. In this case is possibility of the sequential processing of right and left side of profile of gear teeth of wheel different spiral cutting edges. It provides the increase of firmness of tool, diminishes auxiliary time, except the necessity of refixturing of wheel and promotes the productivity of process. For the effective use of shaver with spiral cutting edges it is important to define the exact meaning of amount of possible regrinds. An algorithm that allows to define the amount of possible regrinds of shaver is presented in the article
