Gear form is precisely , plotted by portray point . for friendly user interface , the dialog - box is given , using dcl language to compile dialog box program . because the given program can not only output all the optimum basic parameters of pump gear , but also simulate the meshing process of a pair of pump gears , gear pump can be designed and manufactured economically 精确绘出泵齿轮的轮齿几何形状，尤其精确绘制出了标准齿轮滚刀切出的齿根过渡曲线，演示了国标双圆弧头标准滚刀加工泵齿轮的过程，并实现了泵齿轮副的啮合仿真，这些对检查轮齿干涉以及确定齿轮泵的卸荷槽位置和形状提供了依据。
The machine suit for repairing side , divid cutling , pressure line of corrugated paperboard , it adopt thinblade dividing paper and sharp blade of automatic rubbing , the dividing paperboard is neat and no rawedge , the guality of paperbourd is improved , reducing scrap in behind working procedure , it is first select machine of factory 本机适用于瓦楞纸板的修边、分切、压线、由于采用薄刀分纸，且经自动磨削后的刀刃锋利，使分切出的纸板边缘整齐，无毛边现象，可大提高纸板质量，有利于后道工序减少废品提高纸箱质量，是纸箱生产厂的首选取设备。
