"WebThe tolerance zone is symmetrically disposed about the theoretical exact location. By virtue of this definition positional tolerances do not accumulate where theoretical exact dimensions are arranged in a chain (Figs 6.1, 6.2 and 18.55). This contrasts with dimensional tolerances arranged in a chain. Figure 6.1: Positional tolerancing. " - Perpendicularity vs positional tolerance

WebA square object consists of several perpendicular lines/surfaces. That said, perpendicularity is a part of squareness. Aside from that, the object surfaces should be flat or straight, be it for squareness, parallelism, and perpendicularity. The tolerance zones for these 3 terms could be either parallel lines or planes.

WebDec 20, 2024 · From there you can sort of categorize each of geometric tolerances by which of these 4 characteristics they control. So a perpendicularity tolerance controls Orientation. A Position tolerance controls Location and Orientation. So as you can see both geometric tolerances share one of these Characteristics--Orientation. Webperpendicularity, and other such characteristics may be toleranced on a drawing by a symbol. The symbols introduced in this chapter are suggested by the Turkish Standardization Institution (TSE) and extracted from TS 1304. The two basic types of geometric dimensions utilizing tolerances are: a) form tolerances b) positional tolerances.
