Production line improvement based on machining process

The machining process of the second gear in gearbox was taken as an object of study. First, by means of work study technology, the machining process of the second gear was analyzed, and from the view of the production line balance, the bottleneck processes were selected through measurement of standard time. Then, the existing processes were adjusted, and the idea of operational design improvement and eliminating waste in operation was proposed to optimize the production process, the following effects are obtained: the rate of production line balance is raised 67.5%; the output is raised from 205 to 370 per day; the average output per person is raised from 25 to 41. The bottlenecks in process are eliminated and the production order is improved.
