ABSTRACT

In peripheral milling, due to the periodically interrupted cutting process, the dynamic cutting force oscillates periodically and excites vibrations between the tool and workpiece. Under chatter conditions, the vibration developed is sometimes violent and so strong that the amplitude of the vibration between the tool and workpiece is larger than the chip thickness, so that the chip becomes dissected, and machined surface is spoiled by chatter marks.

The main aim of this chapter is to qualify the dynamic behaviour of a thin walled workpiece during the peripheral milling process under a several cutting and tool parameters. A three-dimensional numerical model, allowing the simulation of the peripheral milling process is proposed. This model permits to estimate simultaneously the workpiece displacements and the evolution of the cutting forces during time.
