Abstract
The relevance of the results of many machining simulations depends on the quality of the cutting force model used. Most of the cutting force models raise problems for uncut chip thickness close to zero. It is mainly due to the management of strong discontinuity and the infinitive limit of the cutting stiffness when the uncut chip thickness goes to zero. Furthermore, the correlation of these models with the experimental results is not very good at low and high uncut chip thickness. To resolve these difficulties, a new model of cutting force is proposed. It gets the advantage to be a continuous law with a finished limit of cutting stiffness when the uncut chip thickness goes to zero. The validation of this model with experimental results in milling and drilling shows a good correlation for a large variation of uncut chip thickness.
