dc.description.abstractThe industrial and increasing requirements of aesthetic products force the shape of product to have the complex 3D shapes. It is common to manufacture such products through three machining steps: rough machining, semi-finishing and finishing. Unlike 2.5D, rough machining step chip formation is different, depending on the tool movement in the machining process. Non-uniform chip load means unbalanced cutting force and the severe change of chip load may increase tool wear and reduce tool life. Although NC-data is generated considering machine dynamics, the irregular chip load may cause tool chatter. Especially, if the NC-data is generated without considering the dynamics of the machine tool, chatter can be created with adverse effects for the machine tool and workpiece. Thus this study proposes a methodology to analyze and generate chatter-free NC-data while maintaining the stability of the tool path. Each NC-block is divided into sections of unit-length NC-blocks and their stability is analyzed. The proposed method is validated through experimental results and is expected to improve machining productivity and quality.
