Five Axis CNC Machine Design
Abstract
It is present the mechanical design of a 5-axis Computerized Numerical Control (CNC) machine tool for learning and use in machining centers. Different methodologies were used, such as the SWOT analysis, Pro-Con, Quality House, morphological table, and decision matrices. Relative calculations are shown to determine the cutting forces, and the finite element analysis with SolidWorks, where a maximum force value was set by the chip removal process, seeking an adequate robustness of the machine for roughing soft materials such as clays, woods, and polymers. Necessary torques are determined for an adequate selection of the actuators for each one of the axes of the machine.
