数控线切割机由于具有能进行直线插补和圆弧插补,以及加工精度高的特点,因而广泛用于加工一些精度要求高和形状复杂的工件或样板。如果通过一定的数学方法,那么还能使它切割一些更为复杂的曲线。例如用直线拟合或圆弧拟合的方法来处理某些只给出一些型值点的非圆曲线等等。特别是圆弧拟合,由于它是用分段圆弧代替曲线,并且相邻两圆弧有公切线,故各型值点均有连续的斜率,而使整个曲线的连接更加光滑。因此圆弧拟合比直线拟合具有更大
CNC wire cutting machine due to its ability to be linear interpolation and circular interpolation, and high machining accuracy, which are widely used to process some of the high precision and complex shape of the workpiece or model. If you pass a certain mathematical method, then you can make it cut some of the more complex curves. For example, the method of fitting a straight line or a circular arc to deal with some non-circular curves that give only some type points and so on. In particular, the arc fitting, because it is the use of segmented arc instead of the curve, and adjacent two arcs have a common tangent, so each type of point has a continuous slope, leaving the entire curve more smooth connection. Therefore, arc fitting has a larger effect than linear fitting
