1、 III In this paper, it is introduced that the virtual manufacturing technology into the production line design of LFC, and it can improve the visualization of layout and design of the production line, so it makes the virtual deign more superior than the traditional design. The research results can m
2、ake the design of casting production line more advantageous and convenient, and get a great improvement in technology, and it is also important to improve the design level of casting production line or other production line design.
