Mechanics of Chip Formation for Conditions Appropriate to Grinding

  • Chapter
Proceedings of the Seventeenth International Machine Tool Design and Research Conference

Summary

A theory of orthogonal machining which has been developed for processes such as turning and which takes account of the dynamic flow stress and temperature dependent thermal properties of the work material is applied to predict cutting forces, temperatures etc. for typical grinding conditions, that is, large negative rake angles, small undeformed chip thicknesses and high cutting speeds. It is shown that for such conditions the theory predicts, in agreement with experimental observations, that the specific cutting pressure, the proportion of generated heat passing into the work and the ratio of the force normal to the cutting velocity to the force in this direction are all very large compared with those encountered in turning, milling, etc.
