The Analysis on Road-building Mechanical Cost Control 公路工程机械设备施工成本控制分析
Nowadays, the mechanical manufacturing enterprises are facing a more fierce competition and their pressure on cost control is intensified. 当前,随外部竞争的不断加剧,国内机械制造企业在成本控制方面普遍面临巨大压力。
Compare with mechanical governor and simulated governor, the digital electronic governor has advantage: circuit simplifying to cut production cost; fulfill variant diesel engine requirement by adapting control system. 与机械调速器和模拟式调速器相比,其优点是:简化了电路,减少了元器件,节约了成本;通过改变控制程序,可以满足不同柴油机的使用要求。
In micro mechanics machining field, the traditional manufacturing approach of micro mechanical parts is to use large precision machine tool to mill. But the cost and the mechanical creep are difficult to control, and the wasted resources and energy are too large. 在微机械加工领域内,传统的制造方法是采用大型超精密机床铣削微小零件,但是存在成本较高、机械爬行难以控制、资源和能源浪费较大等问题。
