直线逼近 meaning in Chinese
straight line approximation
Examples
- Preparations are underway in mexico as hurricane dean makes a beeline for the yucatan peninsula
墨西哥对飓风迪安的防御准备已经开始，目前迪安正向犹卡坦半岛直线逼近。 - In the main - process , the coordinates of nodal points on part outline curve can be calculated by replacing this curve with a linear approximation . the codes expressed in nc program form which can be recognized by nc machine tool are got according to the coordinates of these nodal points in the post - process
在前置处理中，用直线逼近零件轮廓，得到轮廓曲线的节点坐标：在后置处理中，根据这些节点坐标按照数控程序的格式得到数控机床可以辨认的程序代码。 - But all designed software before in our country still have some weakness , for example , the conventional type of cam counld be projected by these software is very little , and used approximation by lines to curves of cam which have bigger error and more nodal points that result in chattering of principal axis . in furthermore , this software of designing cam in fact only has the function of cad . if you want to simulate and work over the designed cam in that software , you will find that you have to export it to other cad / cam system software ( e
随着数控加工在我国的深入开展，真正实现我国的凸轮cad cam就显得非常必要，但以往的凸轮设计软件还存在许多不足，如可设计的凸轮类型较少，大多集中于平面凸轮；且采用误差较大、节点数过密的直线逼近法生成凸轮工作曲线，造成计算时间长，且加工中产生较大振动；同时这些凸轮设计软件基本上只具有cad功能，如果想将设计好的凸轮进行仿真和加工，就必须将图形输出到其它通用cad cam软件(如mastercam等)中，因此这些软件在实际应用中总不尽人意。
