Comparative Study of force Analysis and Heat Generation in Grinding

Heat generation in grinding process is a complicated phenomenon compared to other metal cutting processes. High specific energy is required in grinding in contrast to other machining processes. Before analyzing heat generation process, detailed force analysis is needed as forces play an important role for calculating specific energy in grinding. Several authors have worked on the force models in different ways. Due to plastic deformation and rubbing action, both temperature of the job and grinding wheel becomes very high. This high temperature causes burn, crack formation and tensile residual stress in the job. Two comparative force models and temperature analysis of the job have been presented in this paper. The temperature equation may be solved either by numerical process or some other methods to depict the temperature distribution inside the job.
