It is the students comprehensive use this course and its first courses knowledge of theory and practice for processing technology and jig structure design of an important practice. It is to cultivate students prepare machining process planning and machine tool jig design ability, to improve after graduation design and to the factory is engaged in the process and jig design has very important significance. Curriculum design main material reference the mechanical manufacturing technology foundation course design , the completion of the crank jig design, including the design of the spare parts and special jig design. The whole design process adopts CATIA entity model, and through the software own function finished parts engineering drawings and assembly drawings. And the jig movement process DMU motion simulation design, made the animation. The whole design process to deepen the understanding of the mechanical design, inside and outside the class are of great help.
