所有的制造商具有一个共同的目标:以较低的成本获取较高的生产率。在美国加州Orange的Varco Int’l公司的两家商贸单位,一家是设计和制造机床与装备的制造厂,另一家是油、气钻井钻探仪器仪表制造厂,已成功地使用开放式网络自动化最终地达到提高盈利能力的目的。 Varco钻头系统(Varco Drilling System)的开放式网络自动化指的是位于威斯康星州的Fond du Lac的Giddings＆Lewis公司的一个单元控制器自动地管理流程安排、调度和跟踪大量的装配件。数据处理是通过一个柔性制造系统来处理,该系统由有两台G＆L MC60卧式加工中心,一台G＆L 48″立式车削中心加上调整工作站,中间零件库和一台轨道小车组成。与现有的单台机床性能相 All manufacturers have a common goal: to obtain higher productivity at a lower cost. Two commercial units at Varco Int’l in Orange, Calif., One that designs and manufactures machine tools and equipment and one that manufactures oil and gas drilling and drilling instrumentation, has successfully used open network automation to ultimately To achieve the purpose of improving profitability. The open network automation of the Varco Drilling System refers to a unit controller at Giddings & Lewis in Fond du Lac, Wisconsin, that automatically manages the process scheduling, scheduling and tracking of a large number of assemblies. Data processing is handled through a flexible manufacturing system consisting of two G & L MC60 horizontal machining centers, a G & L 48 "vertical turning center plus adjustment work station, intermediate parts library and a rail car.
