(2) We used the way of layout and flow of program analysis and theory of the way, from process and layout and the way, improved jiwu of Dalian Lootive Works, reduced the handling time and improved efficiency. (3)By improved the crossed red eyes by improving the system positioning to save a process improved the equipment to unite the magnetic and ultrasonic testing to optimize the purpose of merging processes. moved the web hole chamfering processing equipment to the web hole drilled the equipment round to reduce the transition distance. Equipment of finish machiningⅠ would be moved to the main door, while Equipment of finish machiningⅡ would be moved to the opposite to the magnetic detector, which not only reduced the transition distance, but also solved the problem of the crosscutting issues. Changed the temporary location of semifinished products to further reduce the transition distance. And with the all of improvement we reduced the number of processing and saved the processing time. Handling times did not change, but the removal efficiency improved significantly.
