Cylindricity of a hole

WebCylindricity is the 3D version of roundness. It assesses how closely an object comes to a perfect cylinder, meaning that it is not only round, but also straight along its axis. The simplest example that demonstrates the need for cylindricity is a pin which is required to pass completely through a bore with a tight diametral tolerance. WebSep 14, 2016 · For starters, there are three categories of geometric tolerances: Form Tolerances: These tolerances control the part or feature geometric shape and include …

What Is Cylindricity? Geometric Dimensioning & Tolerancing

WebA part's-eye view of a boring bar. In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder. WebThe cylindricity control requires each roundness circular tolerance zone to be on the same straight axis and have the same diameter. Note that doing a 100% inspection of roundness across a surface like this is, arguably, technically impractical (if not impossible), as it requires an extremely high number of measurements (theoretically infinite).
