Thermal analysis of surface grinding process by using design of experiments (Part-1)

Grinding in general is a very complex material removal operation involving cutting as well as ploughing and rubbing between the abrasive grains and the work material. The high temperatures are major source of thermal damage on the machined surface. It can lead to phase transformation in the materials being machined. It can also cause the workpiece burn, which is highly undesirable. In present work a simple moving heat source model has been developed to estimate maximum workpiece surface temperature during surface grinding process. The model is validated by using Design of Experiments (DoE) techniques by using Taguchi Orthogonal Arrays.
