在线切割加工中，常会遇到切割类似放射状（等分或不等分）异形槽口的圆体工件。有些工件体积较小，由于切割槽口形式与工件卡位互相矛盾，不但加工难度大，而且相对于形位及尺寸精度要求高的工件，就更难确保产品质量。经不断观察发现：凡具备某些精度的待切割工件，外表尺寸
In the online cutting process, often encounter the cutting radial (equal or unequal) shaped notch of the circular workpiece. Some workpieces are small in size. Due to the inconsistency between the form of the notch and the workpiece jamming, the workpieces are not only difficult to process, but also more difficult to ensure the quality of the workpieces.
