Why Heat and Mass Transfer?

Why Heat and Mass Transfer?

Heat transfer and mass transfer are kinetic processes that may occur and be studied separately or jointly. Studying them apart is simpler, but both processes are modelled by similar mathematical equations in the case of diffusion and convection (there is no mass – transfer similarity to heat radiation), and it is thus more efficient to consider them jointly. Besides, heat ... Read More »

Analysis of Chip Formation

Analysis of Chip Formation

The first step in a consideration of the mechanics of chip formation is to identify correctly the type of chip involved (steady state, BUE, discontinuous, wavy, or sawtooth). If, at the outset of a metal cutting analysis, an incorrect chip type is assumed, the results obtained may be misleading. It is extremely difficult to predict the type of chip that ... Read More »
