Proposta de metodologia para ensaio de rebolo na retificação plana frontal

Abstract

This work consists of analyzing works and scientific articles to choose the most appropriate methodology to perform efficiency tests and grinding wheel wear at the Metrology Laboratory at Universidade Federal de Juiz de Fora, considering not only the equipment that is already there, but also perform indications of new equipment to be purchased in the future for the test bench. Since there is no standard that specifies this type of laboratory test, the methodology chosen is the one that best fits the reality of our laboratory, taking into account the attempt to obtain control over the largest number of possible variables in this process. grinding machining. The parameters measured or calculated by most of the tests on the articles and which were indicated for use at UFJF Laboratory are: quantity of lubricant, temperature, wear of the part and cutting tool, tangential force and normal force, energy, G ratio and finish superficial. In addition, a method for determining the power of the two- -phase electric motor has been suggested, as well as a way to find the temperature in the cutting zone. Finally, a methodology was proposed for testing the grinding wheel in the frontal flat grinding.
