Machine-vision-based surface finish inspection for cutting tool replacement in production

摘要

A quick and reliable assessment of machined surface finish is required for quality control in shop floors. This paper presents a machine-vision-based approach to inspect the turned surface in finishing operations. The distribution pattern from a laser scattering image is used to characterize the topography of the surface finish and to set criteria for cutting tool replacement. Compared with conventional surface inspections, this approach gives a feasible solution to assure machined surface finish and to establish reasonable criteria for cutting tool replacement in production.
