Rubbing

Grinding processes are widespread in the
manufacturing landscape and provide a unique method
of shaping high-strength metals. As an important
industrial operation grinding practitioners and
researchers alike are driven to continually optimize
the process' efficiency. As a result, this work
investigates the fundamental aspects of how metal is
removed during the grinding process. More
specifically it delves into the micromechanics of how
individual grits interact with the machined metal.
Through various phases, each grit rubs along the
surface, plows material, and finally removes the
metal. Experimental, analytical, and finite element
investigations were used to explore the
micro-mechanics of the rubbing and plowing phases. As
a consequence, a finite element model was developed
and validated, one of the first models capable of
simulating both phases accurately. The results
presented here should be of interest to grinding
researchers with a view towards fundamental
exploration of the grinding process.
