Opis

Grinding processes are widespread in themanufacturing landscape and provide a unique methodof shaping high-strength metals. As an importantindustrial operation grinding practitioners andresearchers alike are driven to continually optimizethe process' efficiency. As a result, this workinvestigates the fundamental aspects of how metal isremoved during the grinding process. More specifically it delves into the micromechanics of howindividual grits interact with the machined metal.Through various phases, each grit rubs along thesurface, plows material, and finally removes themetal. Experimental, analytical, and finite elementinvestigations were used to explore themicro-mechanics of the rubbing and plowing phases. Asa consequence, a finite element model was developedand validated, one of the first models capable ofsimulating both phases accurately. The resultspresented here should be of interest to grindingresearchers with a view towards fundamentalexploration of the grinding process.
