Metodologia de simulação de maquinagem de superfícies planas e furos num centro de maquinagem através da aplicação de software CAD/CAM

Abstract

CNC (Computer Numerical Control) machining is a fundamental technique in the manufacture of high-precision mechanical components. The efficiency and quality of this process largely depend on machine programming and control. In this study, the use of CAD/CAM software was explored as a powerful tool to optimize production and minimize errors in CNC machining. The study describes the basic principles of milling, highlighting the challenges and complexities involved. The objective is to present the basic concepts and advantages of these computational tools in the machining area, as well as the main steps for carrying out a simulation of a manufacturing process. The methodology consists of modeling the part, the tooling and the CNC machine in CAD software, generating the machining program in CAM software, and checking the result of the operation in simulation software. Through this approach, it is possible to optimize the time, quality and cost of the final product, in addition to avoiding errors and accidents during the execution of the process. The work also presents some practical examples of CNC milling simulation, showing the steps and parameters involved in each case. Furthermore, we present a detailed analysis of the CNC machining simulation steps using CAD/CAM software. The study demonstrate how these tools can be used to create 3D models of parts, generate tool trajectories, simulate machining operations, and analyze potential interferences and collisions. Simulation is key to avoiding costly errors and improving production efficiency. Finally, the benefits of applying these tools were discussed, including reducing material waste, increasing dimensional accuracy and saving programming time. This work highlights the importance of a solid CNC machining simulation methodology and how CAD/CAM software plays a fundamental role in improving the efficiency and quality of manufacturing processes. Understanding these concepts is crucial for professionals and companies looking to optimize their CNC machining operations.
