Abstract
With the development of modern science and technology and modern industrial production, the CNC Bending meet the increasingly demanding with high-precision, making the traditional manual measurement has not adapted or does not meet the actual demand for testing. NI’s application software platform
of labview and its production of the image acquisition card combining the two have a different measurement methods, the use of image acquisition card collecting images, the images of the two values, edge processing mode of operation, received a smaller error Precision images, transmitted to the computer, using labview software Bending corners angle measurement，through the research and study,we know the programme has a high possibility.
In this paper, the project design of using a powerful graphical design language (G language) labview programming. HCI has friendly and intuitive interface and a powerful visual data analysis and control equipment, and other characteristics. Papers focused on the use of image acquisition card with IMAQ Vision Build to a graphics processing module, and then labview achieve Bending angle measurement system of the NC Bending automation, intelligent, and the improvement of NC and its importance has increased Significance.
