Research On Improvement Of Assembly Line Balancing In S Company

As the strategy of Industry 4.0 proposed by the Germany,following this strategy,China proposes the "Made in China 2025" plan.The objectives of this plan are to enhance the manufacture level of China,to realize intelligent manufacturing,to make Chinese manufacturing more powerful.As one of the most important state-owned enterprise,facing the increasingly fierce market competition,this machine tool manufacturing enterprise invested lots of money to research and develop i5 control system with their ownintellectual-property rights.How to make the i5 control system productization and enhance the capacity of the machine tool based on i5 control system becomes the keypoint for this enterprise to derive the competitiveness,enhance enterprise image,win the market share and improve enterprise performance in the background of Industry 4.0 and "Made in China 2025".As the research object of this thesis,the current situation of assembly line of C5 series intelligent lathe based on i5 control system is researched.According to the situation of low line balancing,assembly line of C5 series intelligent lathe is researched and improved based on the theories of industrial engineering and line balancing.(1)Analysing the current situation of assembly line of C5 series intelligent lathe of S company.Finding out the main problems in production of assembly line.(2)Assignments of processes are decomposed and time study is made to find out the processes with unreasonable loading."5 W1H" skill and "ECRS" principles of IE methods are applied to improve the processes by eliminating and combining and rearranging the problematic processes to make the labor time of each process harmonious.And then the layout of assembly line isrearranged according to process recombination.In the meantime,the supply methods of important material and storage methods of material in work station of assembly line are also improved.(3)Evaluating the expected effect of improvement.After improved,total labor time of assembly line is saved,capacity is enhanced,the evaluation indexes of line balancing,including line balancing and losing,smoothness Index,operator effiency,are also improved obviously.All of them make the comprehensive benefits of this enterprise improved.The implementation of improvement plan for assembly line balancing of C5 series intelligent lathe lays the foundation for the line balancing improvement of the other assembly line in this machine tool manufacturing enterprise.It has some realistic significance.
