ABSTRACT:
Using parameters such as diameters of a rough cutter and a finishing cutter, a position of a tool at cutting work completion in a rough work, a finishing cutting area, specifications of a rotating tool (the number of cutting edges, a cutting force eigenvalue, a compliance transfer function), etc., a cutting force acting on a cutting edge of the rotating tool is found, and results thereof are made use of to analyze a characteristic equation being a loop transfer function of a vibration system composed of the rotating tool and a work, whereby it is possible to predict presence of generation of self-excited vibration of the finishing cutter performed after a rough work in a shoulder cutting work. Thereby, the rotating tool operates stably in a finishing work and besides shoulder cutting of a work can be performed in a high work efficiency.
