Abstract |
|
High temperature rise in grinding process can cause burning of the needle. The primary objective of this paper was to develop an improved theoretical thermal model which would predict the grinding temperatures, the energy partition to the needle and heat flux distribution within the grinding zone. In all cases, the maximum grinding zone temperature rise was less than 120°C.The energy partition to the needle was found to be 6.2%.Such low energy partition is consistent with thermal model which takes into account conduction to the needle, conduction to the abrasive grains, and cooling of the needle by the fluid at grinding zone. The secondary objective is to optimize temperature rise between wheel and needle contact zone in a cylindrical grinding process so as to reduce thermal damage and thereby grinding burn. |
