  3、刀具的制造误差及弹性变形

  天博体育很多人都有这样的经历,就是在前一刀车削了几毫米切深以后,发现离想要的尺寸还差几丝或者十几丝时,再按计划进行下一刀切削时,发现多切了很多,尺寸可能超差了。那么这样的情况天博体育认真分析过其中的原因吗?有人说,这可能是因为机床间隙比较大所致,而在同一进刀方向上是不会受间隙影响的,其真正原因就是弹性形变和弹性恢复。

  4.2、JIZHUNWEIYIWUCHA

  工件在夹具中定位时,由于工件定位基面与夹具上定位元件限位基面的制造公差和最小配合间隙的影响,导致定位基准与限位基准不能重合,从而使各个工件的位置不一致,给加工尺寸造成误差,这个误差称为基准位移误差。

  6、切削要素对表面粗糙度的影响

  刀具不是很锋利的情况下,切深太小,甚至比刀刃厚度还小时,已经不是正常的切削了,只能属于“刮”或“研”,所加工工件表面粗糙度会下降,工件表面出现细微白丝,好像笼罩一层白雾,所以要注意控制。
