Influence of Tool Runout on Cutting Mark Control on Machined Surface by Ball-Nose End Mill with a Five-Axis-Controlled Machine Tool

Abstract:

This study focused on cutting trace control for machining three-dimensional contours, such as molds, with high accuracy and efficiency. In this study, experiments were conducted to generate a honeycomb structure with hexagonal cutting marks and a lattice structure with square cutting marks in the cutting process of a two-blade ball-nose end mill using a runout adjustable holder, with the aim of adapting the cutting-mark control to the production level. In this study, the relationship between runout, machined surface, and cutting force is shown, and the effects of runout, honeycomb structure, and lattice structure on surface adsorption are investigated and evaluated for applications in the production field.
