This paper presents details of developing a computer animation system for chip formation in oblique machining process. The 3-D chip animation model developed integrates chip flow equation, chip curling patterns, chip geometrical features and mathematical expression for 3-D helix surface. Based on the input conditions (chip breaker parameters and cutting conditions), a computer program is developed to convert the parametric prediction into a series of dynamic graphs demonstrating chip formation process. The methodology presented in this paper may provide an assistance for the machine operator to choose the machining conditions or for the process planning designer to evaluate the chip control effect.
