Tolerances and 
Surface Finish 
Figure 40.3 A plot of achievable tolerance versus surface roughness for assorted 
manufacturing operations. The dashed lines indicate cost factors where an increase in 
precision corresponding to the separations of two neighboring lines gives an increase in 
cost for a given process (for a factor of two). Source: M. F. Ashby, Materials Selection
