Abstract

As an important internal thread machining method, tapping is frequently among the final operations performed on elaborately transformed manufactures. The added value is often near its peak when the tapping operation is carried out. Consequently, conservative cutting conditions often are employed to avoid costly tap failure. Taps and tapping also are amongst the most complex and least understood cutting tools and processes. In this paper, the geometry and specification of straight flute taps are discussed, followed by an outline of the development of computer-aided predictive models for side force, thrust force, and torque in machine tapping, based on Armarego's 'Unified-Generalized Mechanics..
