Simultaneous Requirements in GD&T: What They Are & How They Work
Geometric Dimensioning & Tolerancing (GD&T) uses symbolic language to control geometric relationships. A simultaneous requirement means multiple features must meet their geometric controls together—in the same setup and referencing the same datums in the same order and material condition.
ISO 14405-1:2016 Circular Options
Within the ISO 14405-1 are options which will be applied to circular features. These will be indicated on the print.
Understanding the 6 Degrees of Freedom (Copy)
Understanding the principle of the 6 degrees of freedom is essential to aligning your part correctly on the Coordinate Measuring Machine (CMM). When a part is placed on the CMM the location of the part is not known. It must be defined by using several features known as datums.
How to Calculate Chord Length
A chord of a circle is a line segment with its endpoints on the circle. The diameter of a circle is a chord that intersects the center of the circle. A line that contains a chord of a circle is known as a secant of that circle. It is possible to calculate a chord's length when the circle's radius and the central angle of the chord are given. We can also calculate a chord's length when we know the circle's radius and distance of the chord to the center of the circle.
