Simulation Techniques in CAD-CAM Processing by Milling of Surfaces on NC Machine-Tools

摘要

The paper presents theoretical and practical-applicative aspects on some methods for the NC simulations using the CATIA v5 software, Machining module. An application is proposed for the milling procedure to process complex surfaces (plane and complex sculpture surfaces). Some practical optimization criteria are used, such as: correct choose of the machine-tool, type and durability of the cutting tools, paths and division patterns of the stock left for machining, optimum cutting parameters (cutting speed and feed speed), efficient use of the machine-tool, reduction of the machining time, precision conditions etc. The paper contains images and numerical data obtained from simulations allowing to draw conclusions regarding the possibilities to optimize the generation of complex surfaces whose generating and directing curves are not defined analytically.
