Implementation of the CAD systems in the field of machine design allowed more possibilities for the design of free-form surfaces, which are especially used in the field of shape design within the automotive and consumer industries. The connection of the CAD systems with the CAM machining technologies has brought a revolution in the field of machining these surfaces. What until recently could be machined with a great effort on copy milling machines, where the clay or laminate model was an original, can now be produced using a virtual model, whereby the tool copies the shape of this model. The CAD/CAM systems already offer analyses during design, which can verify the manufacturability of the modelled surface. The CAM systems offer a number of tool movement strategies for machining a given surface. This paper is focused on the selection of the most suitable strategy for machining the shaped surfaces of the active parts of press tools for the production of automotive parts. It points out the importance of the CAD/CAM data needed in the stage of technological preparation of production, because they have a significant impact on the achieved surface quality. This paper deals with strategies of machining a planar inclined surface using horizontal and vertical machining strategies. The next part of the paper deals with machining of the Free Form Surface and the final part of the paper uses the described strategies for machining the shapes of the die cavity for connecting rod fittings. The experimental part is concentrating on the selection of the most suitable strategy of die milling for the production of the connecting rod (car internal combustion engine part). Simulations of production and the production of details from two different materials are realized on individual details of the mould. The resulting quality of the treated surface was evaluated based on the evaluation of surface roughness.

“…It is clear the influence of the machined material on the surface topography. For example, Fabian et al [45] have verified the influence of the feed direction on the finishing operation of a 45° inclined surface in aluminum alloy. The L/D ratio in that work was equal to 4, with a ball nose tool 5 mm in diameter with a 20-mm swing.…”

CNC milling of curved surfaces is a common task in the manufacture of molds and dies of products used in various industrial sectors. Notably, in recent years, the use of hard milling has helped manufacturers to obtain these parts with shorter lead times, since the part is machined in a single setup without the problems caused by part distortions from the tempering process. In this work, cylindrical surfaces were machined in AISI H13 steel tempered and annealed to 52 HRC using hard milling and high speed milling concepts in the finishing stage. The cutting tool was feed along either upward ramping or downward ramping directions, and the quality of the texture of the obtained surfaces was evaluated as well as the wear of the ball nose cutter. The results showed that the surface is deteriorated when milling is performed in the downward direction (surface roughness equal to 6.93 μm) compared with the upward direction (2.17 μm). Also, vibration marks are present on the machined surface in the downward direction. In addition, surface roughness is worsened when the tool performs the cut primarily at regions away from the center of the tip of the ball nose cutter. On the other hand, the surface roughness is worsened when cutting with regions near the center of the tip of the ball nose cutter when milling in the upward direction. It was noticed that flank wear in both upward and downward directions was low (less than 10 μm), and micro-chipping was observed in the cutting edges.

The article deals with the correction of the programmed path lathe tool with a tip radius size. This correction is required to use in turning shaped surfaces. The programmed tool path can be corrected in various ways. In the first case, the calculation of the correction applied through mathematical relationships. The latter was used for automatic correction by the preparatory functions. Subsequently, the manufactured parts are measured, compared and evaluated characteristics shaped surfaces. Based on the evaluation method was recommended correction tool tip for the production of shaped surfaces.
