ターンミリングにおける切削状態と加工面性状の解析的予測

抄録

Difficult-to-cut materials, which are increasingly used in the aerospace and energy industries, cause significant tool wear and high tool temperatures during machining. Turn-milling is one of the machining methods that are currently attracting attention as a solution to these problems. The main feature of turn-milling is that the milling tool cuts the work material rotating at a low speed, and the intermittent cutting by multiple cutting edges has the advantage that cutting heat can be dispersed to each cutting edge and chips can be broken up reliably. In turn-milling using a 5-axis machine, there are various options for tool posture, which makes it difficult to understand the cutting status. In this study, a point cloud model is used to simulate machining with tool postures such as tilt and lead angles of the tool rotation axis. The surface roughness is to predict the effects of cutting conditions and tool posture parameters in 5-axis turn-milling, focusing on the generated cut trace shape and surface properties.
