| Abstract: | For free-form surface NC machining,it is very important to find the best tool path generation method.In this paper,based on the open-source 3D library Open CASCADE(OCC)and the programming development environment Microsoft Visual Studio 2010(VS2010),the free-form surface expressed by b-spline as the object of use,a tool path mapping algorithm for NC machining of free-form surfaces is proposed by research the method ofreusing existing similar tool paths.This algorithm adopts the idea ofprojection method.In order to verify the effectiveness and feasibility of the algorithm,the experiment establishes five kinds of free-form surfaces,starts the designed trajectory mapping algorithm,and the quality of NC machining path of output surface can meet the design requirements,the reuse of tool path is realized. |
