Perpendicularity of a hole

WebSep 14, 2016 · Perpendicularity: This tolerance is specified in relation to two other datums and controls the orientation of the surface as it deviates from 90 degrees. The tolerance zone specifies the envelope within which the surface may vary from a perfectly perpendicular state. Perpendicularity. Rasis, E.P. (2011). Technical Reference Handbook … WebAs has been noted, perpendicularity can apply to both faces, but also axes and derived median geometry. This means that quite a wide range of geometries may be eligible to be controlled with a perpendicularity call-out; a few generic example models are shown below. Note that this is a relative control between two features, so pairs of faces ...
