“…The other one is based on special strategies focused to machining the specified type of shaped surface. The example is tool path generation for pocket machining with optimizing the federate as described in [11]. Despite complicated shapes of dies for their production, 3-axis milling operation is often sufficient [12].…”

The paper describes stamping punch production from the view manufacturability and quality of stamping punch active surfaces. The tin car-body stamping punch has been chosen as a subject of experimental work. The experimental stamping punch has been made out of Textit and production stamping punch has been made out of tool steel X210Cr12. Milling strategies has been proposed and verified using CAM software SolidCAM considering the maximum Scallop Height. The roughness parameters Ra and Rz measured on selected areas of stamping punch shaped surface were compared to Scallop Height. Manufactured areas on shaped surface were optically evaluated as well. The application of proposed procedure is shown as an example of manufacturability for experimental and production stamping punch designed for complex parts production.

To cite this version:Christophe Tournier, Claire Lartigue. 5-axis iso-scallop tool paths along parallel planes. ABSTRACTThis paper presents a new method of computing constant scallop height tool paths in 5-axis milling. Indeed, usual iso-scallop tool path computation methods in 3-axis or 5-axis milling generate tool path self-intersections, which prevent from reaching the required quality and productivity. The proposed approach consists in following parallel planes in 5-axis milling to avoid self-intersection of the tool path. The constant scallop height is guaranteed by modifying the machined strip width by means of the orientation angles of tool axis (yaw and tilt angles). Resulting scallop height and surface roughness are simulated using the N-Buffer method.

“…Monreal and Rodriguez [5], Tournier et al [13], and Tapie et al [9,10] have worked on the adaptation of the tool path to the HSM machine cinematics. Pateloup et al [7,8] and Mawussi et al [3] have structured a methodology to help choose the machining strategy for such a pocket geometry in a context of high-speed machining. The results show that the geometrical criteria of analysis must be completed by a dynamic study.…”

“…Tapie et al [9,10] and Pateloup et al [7] have integrated the dynamic modelization in order to determine the causes of the variations applied to the feed rate. This modelization integrates the jerk, the acceleration, and the interpolation cycle time so as to explicit the slowing down of the machine in linear and circular interpolation.…”

Our two major concerns, which should be taken into consideration as soon as we start the selecting the machining parameters, are the minimization of the machining time and the maintaining of the high-speed machining machine in good state. The manufacturing strategy is one of the parameters which practically influences the time of the different geometrical forms manufacturing, as well as the machine itself. In this article, we propose an optimization methodology of the machining strategy for pockets of complex forms. For doing this, we have developed analytic models expressing the feed rate of the cutting tools trajectory. Then, we have elaborated an optimization method based on the analysis of the different critical parameters so as to distinguish the most suitable strategies to calculate the cutting time and define the machine dynamics. To validate our results, we have compared them to the experimental ones and also to those found in literature.
