箱体零件的柔性制造技术在拖拉机制造中的应用(中文2300字,英文1400字)
1 国外箱体零件的柔性制造技术
1.1 柔性自动线
    为适应多品种生产，在上世纪80年代初，开发出了柔性自动线(FTL)(见图1)。这类自动线是由多个数控自动化加工工位通过自动化的按一定方向的工件流联接而成的。在数控加工工位上视具体加工任务可选用不同类型的数控加工模块，这些加工模块按其数控轴数，有单轴、双轴和三轴控制；按其主轴数，有单主轴和多主轴加工模块。由于这些模块是数控的，因此，当自动线由加工此种品种的工件转换为另一种品种的工件时，可通过改变数控程序来实现自动换刀、自动更换多主轴箱和自动改变加工行程、工作循环、切削参数以及加工位置等，以适应变型品种的加工。

Flexible manufacturing technology of 1 foreign box parts
1.1 flexible automatic line
To adapt to the production of many varieties, in the early 80 century, developed a flexible automatic line (FTL) (see Figure 1). This type of automatic line is flow and connected through automation according to a certain direction of the workpiece by multiple CNC automatic processing station. In numerical control machining position of specific processing tasks can choose different types of numerical control processing module and the processing module according to the CNC CNC axes, uniaxial, biaxial and triaxial control; according to the number of spindle, single spindle and multi spindle machining module. Because these modules are CNC, therefore, when the automatic line workpieces by processing of such species conversion is another variety of the workpiece, by changing the NC program to realize the automatic tool change and automatic replacement of multi spindle box and automatically change the stroke process, cycle work, cutting parameters and machining position, in order to adapt to processing of variant species.
