The data that defines an SVG path element consists of a series of coordinate values defining points, and additional control characters preceding a point.
定义SVG路径元素的数据由一系列定义点的坐标值及在点之前的附加控制字符组成。
To do this, the monotone curve is firstly drawn, and then without finding the coordinate of the inflexion point, the NC machining path can be obtained by the method of automatic direction control.
首先对单调NC轨迹曲线进行绘制，进一步用不求极值点坐标而实现自动控制变向的方法，求出NC加工轨迹；
Secondly, the meshing path of the contact point of SCMW is deduced based on the meshing function of space curve and the space coordinate transformation.
其次，本文在前期研究建立的空间曲线啮合方程基础上，结合空间坐标变换，推导出空间曲线啮合轮的啮合轨迹；
