Linear interpolation for creating a circular path would be quite inappropriate because the programmer would be required to specify the line segments and their respective end points that are to be used to approximate the circle.
线性差补用来差补圆是不合适的因为程序源需要明确指定线段部分,线段数量和各自的终点来大约模拟圆弧。
Circular interpolation schemes have been developed that permit the programming of a path consisting of a circular arc by specifying the following parameters of the arc: the coordinates of its end points, the coordinates of its center, its radius, and the direction of the cutter along the arc.
使用圆弧只要给定以下参数,圆弧终点坐标,圆心坐标,半径和刀具沿圆弧路径的走刀方向。
The tool path that is created consists of a series of straight-line segments, but the segments are calculated by the interpolation module rather than the programmer.
差补也是由许多小的直线段来实现的,但这些小线段的参数由差补模块来计算出来的,而不是程序员设定的。
The cutter is directed to move along each line segment one by one in order to generate the smooth circular path.
切削是沿着每一小线段一个一个的进行以产生光滑曲线路径。
A limitation of circular interpolation is that the plane in which the circular are exists must be a plane defined by two axes of the NC system.
圆弧差补的局限性是圆弧路径所在平面是由数控系统中两轴所决定的平面。
