英语翻译
The error of measurement of a zero-type MH in a NC machine should be accounted for in assigning the automatic workpiece basing cycles,in the case of basing on a cylindrical pin or hole,the basing error will be eat = 0.5(o w + o a + Smi n) 2,where o w is tolerance on the base dimension of the workpiece; o a is the tolerance on the base dimension of the at- tachment; Smi n is guaranteed clearance.
The value of Smi n is usually selected in the 0.005-0.02 mm range.Tolerance on the base dimension of the attachment with the base element diameter of not less than i0 mm is 0.01-0.02 mm.By substituting the obtained data in (i),we get o w > 0.035 mm.
Use of MH in multipurpose NC machines showed that these did not find use for direct measurement of workpiece dimensions.
Exceptions to the above are cases of control of dimensions of nonrigid workpieces.The automatic basing cycles worked out facilitate elimination of manual trueing of the workpiece or attachment on the machine tool and makes it possible to do away with the use of attach- ments with workpiece basing elements for individual production

测量误差的zero-type MH的数控机床中应占的自动工件在分配基础周期,在案件的基础上的孔,筒形销或基础错误是吃= 0.5(o w + o + Smi n)在2号o w是宽容的基地,工件的尺寸公差是阿尺寸的基础上,tachment;Smi n是保证间隙.
Smi n的价值通常是选择在0.005-0.02毫米范围.在此基础上尺寸的公差的连线与基地的不小于元件直径的mm是0.01-0.02 i0毫米.所得数据,替代(我),我们在得到阿魏> 0.035毫米.
在多用途使用MH数控机床表明这些没有发现使用直接测量工件尺寸.
以上是例外情况下控制的维度nonrigid零件的加工.基础周期制定的自动消除手工trueing方便,工件的或连线在机床,使人们有可能掉这使用附上-基础元素与工件闪光个人生产
