Abstract. In this paper I want to presents the process for manufacturing one complex parts made by aluminum alloy. For manufacturing this complex part I used CAD/CAM software, CNC milling machine and same special tools. Starting from the 3D model made in SolidWorks was manufactured this complex part, using new strategies for CNC milling. To be made this chain of pieces it is necessary to use smart software for this process. Introduction One of the most important methods used in manufacturing CNC parts it is milling technology used in industry of automotive and not only. It has various distinct advantages over the other cutting technologies, such as: high machining versatility, high flexibility and has been proven to be an effective technology for processing various engineering materials [1, 2]. In the manufacturing industry it is necessary to make 3D complex parts with are be processed in a short time, having good surface quality and high dimensional accuracy [3, 4]. Using CAD/CAM software it can make complex shape for all the industry [5,6]. In this software we need to have a lot of strategies to can process complex 3D shapes with small details [7, 8,12]. The analyze of 3D model In SolidWorks software it started the analyzing a 3D model of this parts. This is show in the figure 1. This piece is made from a special aluminum alloy for molds. This part was ordered by a private company, and this company has made the 3D model. Fig. 1.
