Abstract
The concept of apparent strain analysis when applied to orthogonal cutting is a much simplified approach. It is based on the principles of plasticity theory of work done expressed in terms of the equivalent stress and strain.
Previous work by Thompson et al included work hardening characteristics of the work material but the rate of strain and temperature effects were not considered. In this paper the analysis is extended to incorporate the effect of temperature and strain rate on the various parameters in orthogonal machining and the results are discussed in relation to those obtained experimentally by Merchant and also those predicted by Oxley et al using conventional shear (zone) model analysis of orthogonal machining. Comparison is also made with the results predicted using apparent strain analysis without taking strain rate and temperature effects into account as proposed by Thompson et al.
