ABSTRACT:With the development of modern society and economy, people's living standards are improving. Cloth color requirements are significantly improved by the public. The chromatic aberration detection has its important applications in the textile printing and dyeing industry. In order to eliminate the subjective differences of human eye in product testing, it takes the machine vision detection method for chromatic aberration detection for industrial products. In the textile industry, the color measurement and control become more and more attention of the modern industrial manufacturer, and color measurement instruments are also much acclaimed. Digitized design manufacturing technology of application of CAD / CAM conduct product is a hot spot problem of current product development, carrying out digitized design and manufacturing of the color test instrument products  through the application of CAD software can make the students understand the advanced design technology of the machinery industry, to master the advanced digitized design manufacturing concepts and knowledge to be familiar with the mechanical product development and design process, and complete product development and design work through skilled application of large-scale integrated CAD software. During the process of digital design of component test equipment, we must firstly consider the transmission design of industrial camera. According to production needs and arrangement position of product color bar, we can determine the transmission mode of the industrial camera, and then determine the platform of X-Y coordinates, rolling guide, ball screw and motor model. When designing the parts, we need plot the two-dimensional drawing, and then plot three-dimensional diagram by the two-dimensional drawing. We can inspect the reasonableness of system design after assembling the parts. 

　　　Design of this project need create three-dimensional model, two-dimensional model and structural design for chromatic aberration testing equipment through mastering UG software and AUTO-CAD software respectively, and complete the assembly modeling. It need select the model of the key components of chromatic aberration testing equipment through calculation and check, such as ball screws, rail, and motor and so on. So we can complete the digital prototype of the product, and draw a complete engineering drawing including a set of assembly drawings and the parts drawings.
