  • Grinding burn formed on the ground surface is related to the maximum temperature of workpiece surface and wheel temperature in the grinding process. The thermal characteristics of workpiece and grinding conditions on the surface temperature of the oxidation growing layer after get out of contact with the grinding wheel. The assumption used in grinding power signatures leads to the local temperature distribution between grinding wheel and workpiece, i.e., a single curve determines temperatures anywhere within the grinding wheel at anytime. This information is useful in the study of the grinding bum penetration into the wheel and thus provides an presentation of grinding trouble monitoring for the burning. On the basis of grinding power signatures in the wheel, thermally optimum conditions are defined and controlled. To cope with grinding burn, the use of grinding power signatures is an effective monitoring systems when occurring the grinding process. In this paper, the identified parameters suggested in this study which are derived from the grinding power signatures are presented.

  • This paper experimentally describes the grinding characteristic of discontinuous grinding wheels in creep-feed grinding. In creep-feed grinding, grinding temperature increases rapidly and thermal damage such as a burn occurs on a workpiece. Discontinus grinding wheel with Conventional grinding wheel shows an exellent cooling effect has been developed. The wheels have 6, 12, 24 pieces of slotted which compare with characteristics of each wheels
