五、空间角度的误差分析前面的讨论只解决了夹具角度名义值的计算。但在实际工作中某些零件图中所给出的角度公差较严,这时就要进一步解决夹具角度调整的精度问题。即是解决夹具的θ和φ角按照什么精度调整能满足图纸要求。为此,有必要对夹具所产生的角度误差进行定量分析。 V. Spatial Angle Error Analysis The previous discussion only solves the calculation of the nominal value of the fixture angle. However, in the actual work of some parts of the figure given angle tolerance more stringent, then we must further solve the accuracy of fixture angle adjustment. That is to solve the fixture of the θ and φ angle according to what the accuracy adjustment to meet the drawings requirements. For this reason, it is necessary to quantitatively analyze the angle error caused by the jig.
