Study on Machinery Manufacturing CAD/CAM NC Machining Technology

With the development of computer technology, CAD / CAM technologies have been widely used in the machinery manufacturing industry. They have brought fundamental changes to product design and manufacturing method. Based on the characteristics of punching machine processing technology, the main content of this paper is the study on boards CAM key technology taking NC machining applications for boards punching as the background. This study takes VC + + software as the platform and widely applies VC + + development tools and OpenGL technology in the process of developing graphical simulation system. The purpose of this study is to achieve drawing function, automatically extract pixels in AutoCAD graph such as holes, and automatically generate NC machining program by the extracted pixels on the basis of the pixel extraction. This can ensure the uniqueness and accuracy of the data, so as to improve the efficiency of programming.
