COMPUTER ANIMATION OF 3-D CHIP FORMATION IN OBLIQUE MACHINING

This paper presents details of developing a computer animation system for chip formation irt oblique machining process. The 3-D chip animati on model developed integrates chip flow equation, chip curling pattern s, chip geometrical features and mathematical expression for 3-D helix surface. Based on the input conditions (chip breaker parameters and c utting conditions), a computer program is developed to convert the par ametric 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 condit ions or for the process planning designer to evaluate the chip control effect.
