摘要

To optimize the cutting conditions in machining, it is necessary to quantify the energy parameters involved in the process. Thus the control of a cutting process is realized if the cutting parameters, the kinematic parameters and contact actions are accurately estimated. To estimate these parameters, original metrological devices have been developed in the various laboratories involved in this study. Force and moment measurement has been carried out using a six component dynamometer. Various image processing techniques allow to determine the chip/tool contact surface and the chip ejection angle. Complete and detailed energy equilibrium realized with those devices has clearly demonstrated the influence of moments on the mechanical power consumed by the cutting process. With these results, a three-dimensional thermomechanical cutting model has been developed. The originality of this model is the complete and continuous definition of the tool geometry, integrating tip ray and edge acuity characteristics. Forces and moments, chip kinematic parameters (chip orientation, tool/chip contact area) can be evaluated. The presented study shows the geometrical and kinematic parameters effects, such as the penetration rate on force and moment values in turning. A correlation is established between kinematic parameters, forces, moments and an original experimental study using an imagery interpretation method.
