The variety of designs of broaches is described by set of geometrical, design and operational parameters of the cutting and tail parts. For an efficiency evaluation of the splines broaches the system of the objective functions of the length for the spline, round and facet parts depending on the scheme of cutting is created. The system of constructive and technological restrictions for basic parameters of a broach is proved. The solution of a task of the choice of the optimal solution is constructed on implementation of an algorithm of dynamic programming. The technique of designing of optimum designs for the splines broaches with the help of the personal computers tools in the environment of MS Excel is automated.
