WebFlatness Control: Perfect flatness is when all points of a surface lie in the same plane. Flatness is a form control. The flatness control (c) defines how much a surface on a real part may vary from the ideal flat plane. Tolerance Zone: The flatness tolerance zone is the volume between two parallel planes. WebAmongst the basic form controls (straightness, roundness, flatness & cylindricity), straightness is unique in that it can also apply to an axis, not just a surface. In these situations, the behaviour of the control is slightly different. Like flatness, straightness can also apply to a virtual feature – in this case a so-called “median line ... WebDec 18, 2014 · Profile of a surface describes a 3-Dimensional tolerance zone around a surface, usually which is an advanced curve or shape. If it is called out on a curved surface, like a fillet on a welded part, the entire surface where the radius is has to fall within the tolerance zone.
