包括剪料在内的广义剪裁加工,由于其生产率高,适于成批生产而早被广泛使用,但所得的制件都有“塌角”和“毛刺”的缺陷,常因此而引起麻烦。用以往惯常的剪裁方法不可能消除这两个缺点,最多只不过是将其减小些而已。 General trimming, including trimming, is widely used as early as due to its high productivity and is suitable for mass production, but the resulting parts have flaws and “glitches” which often lead to troubles. It is impossible to eliminate these two drawbacks in the conventional way of tailoring, at best only to reduce it.
