The objective of this project is to investigate the strength of the correlations between the finish along an edge to the edge geometry and performance when slicing. We used a confocal microscope to measure machined aluminum edges at fine scales. We used geometric multiscale analyses to characterize the edge and determine the relevant scales of measurement. We redesigned a testing device from a previous MQP to apply forces when slicing through material. We used a dynamometer to measure the forces simultaneously. Using the microscope to analyze the edges before slicing, as well as the material after slicing, it was determined that various polished edge finishes resulted in differences in slicing performance.
