The dependence of cut layer volume distribution between cutting teeth of a tap on the constructive and geometrical parameters of the tool cutting part is obtained in the analytical form. It is established that increase of errors of angular pitch between the teeth of a tap resulting from tool manufacturing and resharpening leads to essential redistribution of the allowance volume, falling on the cutting teeth of the tool. It is shown that approximate equal distribution of the allowance is ensured at a uniform angular pitch between the teeth of the tap; in this case, the nature of the load distribution between the cutting teeth depends not only on the angular pitch errors but also on the order in which the cutting teeth are set into operation.
