Determination of effective stress-effective strain relationship for use as a machinability index

Welsh, M. J. M. (College of Aeronautics, 1964-03)

In recent work it has been shown that the effective stress effective strain relationship of a work material is important in determining the shear angle in orthogonal cutting. This note describes the method of obtaining ...
An explanation of the apparent bridgman effect in merchant's orthogonal cutting results

Oxley, P. L. B.; Welsh, M. J. M. (College of Aeronautics, 19)

Abstract In Merchant's modified shear angle solution it is assumed following Bridgman that the shear strength of the work material is a function of the hydrostatic stress. Although Merchant's experimental results confirm ...
Preliminary report on the analysis of the stresses in a die-bolster combination

Oxley, P. L. B.; Welsh, M. J. M. (College of Aeronautics, 1964-08)

An analysis is presented of the stresses in a carbide die-steel bolster combination. Results from a computer treatment of this analysis are given in tabular and graphical form. Suggestions are made as to the choice of ...
The relevance of the mechanics of metal cutting to machinability

Enahoro, H. E.; Welsh, M. J. M. (College of Aeronautics, 1965-08)

INTRODUCTION The process of metal cutting is a subject of great importance to the makers and users of machine tools. Extensive research has gone into the subject but has still left most of the phenomena unexplained. Tool ...
