| Abstract: | On the basis of deepgoing researches on the grinding heat, heat transfer process of the contact zone and unstable state temperature field in the workpiece surface layer during creep feed grinding, a simulation mathematical model which can be used to calculate the time course of temperature field distorting in the workpiece surface layer has been structured,and on these grounds the computer simulation studies of workpiece burn process during creep feed grinding have been completed. The simulation result accords well with the practice of burn process during creep feed grinding, and it takes the lead in explaining the heat mechanism of burn during creep feed grinding, showing that the creep feed grinding is a typical slowly changing course which has obvious premonition characteristics. |
