Tensile strength of sheet material was studied using orthogonal experiment. Test data obtained were fitted and optimized by using Matlab. The 3D map and contour map of the rotating speed, feeding speed and processing temperature on the tensile strength of sheet material was obtained. The mathematical models between independent and objective parameters were established. According to the mathematical models, graphical user interfaces were designed by using LabVIEW programming, through which human-computer interaction was realized and the product quality can be predicted scientifically and accurately. The purpose was to provide reference for production and practice.
