Horizontal-Axis Wind Turbine Blades Mold Manufacture by Using Cutting Processes

The current paper presents the designing and technological manufacturing process of the 2.5kW horizontal - axis wind turbine (HAWT) blades mold. The stages of the process from the 3D modelling to the manufactured parts are presented. Firstly, a CAD model of the blade is realized using airfoil cross-sections and with Mold tools from Solidworks the model of the semi-molds are defined. After then for the technological process a CAM simulation is done. The semi-molds are manufactured by using the cutting process using a CNC machine. The infrastructure that NRDI COMOTI has at its disposal was implied in order to obtain the blades mold.
