WebPerpendicularity, which is a regulation on the perpendicular state in comparison with the datum, is measured using measuring tools or a coordinate measuring machine. This page explains how to do this, as well … WebNov 7, 2014 · Perpendicularity describes angularity at 90° and parallelism describes it at 0°. All of these are profiles of orientation and are used in the exact same way. They also can be used with control of an axis under maximum material condition, although perpendicularity is usually the only one you will ever see with this callout.

WebJan 3, 2007 · A faster, more automated way of making this surface plate perpendicularity check is with an electronic height gage. While the electronic height gage may not have the level of mechanical perpendicularity that is built into a precise master square, it is a very repeatable gage. Since it is repeatable, any inherent inaccuracy can be measured and ... WebOct 12, 2024 · Measuring the perpendicularity of a surface typically requires the use of a height gage, with either the gage or the part locked to a 90° datum to determine how … WebDec 10, 2024 · A profile of a surface specification controls how much the features' surfaces can deviate from being the nominal shapes, which are located and oriented to zero or more datums. For this geometric tolerance, these three aspects work together: Each considered feature's nominal shape and each resulting tolerance zone. free mindful colouring pages
