机械加工费用高,有三个很普通的原因:一为切削时间或周期长;二为昂贵的或专用的工卡具和切削刀具磨损或折断快;三为有些结构形状的机械加工是花钱的,因为它们生产得慢,它们难于在卡具中固定或过早地使切削刀具损坏。在一般情况下,将设计简单地修改一下,就可克服加工中机械上和几何形状上的限制,就能显著地降低产品成本。下列的例子说明修改设计是可以使机械加工的成本减至最低。 High machining costs, there are three very common reasons: one for the cutting time or cycle length; two expensive or special tooling and cutting tools wear or broken fast; three for some structural shape machining is expensive , Because they are slow to produce and they are difficult to fix or prematurely damage the cutting tool in the chuck. In general, simply modifying the design to overcome mechanical and geometric limitations in machining can significantly reduce product costs. The following example shows that modifying the design can minimize the cost of machining.
