Abstract
AbstractIn this paper, cutting forces and tool wear of ceramic cutting tools are investigated by up‐milling high‐density fiberboard under different geometric angles and cutting speeds. The results show that tangential force (Ft) and normal force (Fr) decrease with the increase of rake angle. The values of Ft and Fr at the higher speed cutting condition are lower than that at the lower speed condition. The flank wear (VB) declines with increased clearance angle and decreased cutting speed. The tool wear patterns observed on the ceramic cutting tools are pull‐out of grain, cracking, tipping, and flanking. Abrasive wear and adhesive wear are the main mechanisms of the ceramic cutting tools. In all, on the premise of guaranteeing the ceramic cutting tools’ strength, the ceramic cutting tool with a bigger rake angle and clearance angle is advisable in high‐density fiberboard machining, in terms of lowering the energy consumption and production cost required for machining.
