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.

Form Datum - Calypso

What the Form Datum does is establish a FUNCTIONAL Datum Reference Frame coordinate system, similar to if you were setting up the primary, secondary, and tertiary datums on a functional checking gage. This is ONLY for a datum reference frame and does not modify how the base and secondary alignments evaluate their respective coordinate system. In the screen shot below, you can notice the different origin points are for a base alignment and datum reference frame.

Understanding the 6 Degrees of Freedom

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.

AGILITY S 5-axis multi-sensor CMMs for the shop floor

Designed for shop floor environments

The S range of CMMs provides the ability to accurately measure parts in shop floor environments without temperature control. The rapid data capture speeds provided by 5-axis measurement reduce inspection cycle times, helping production departments keep pace with high volume manufacture. The systems work well in both stand-alone and fully automated production lines.

Cartesian Distance

In this example, the “Primary Datum” is the same as the “Spatial Rotation” and “Secondary Datum” is the same as the “Planar Rotation” inside an alignment. Selecting “Parallel To” or “Perpendicular” specifies the axis direction. i.e. the “X”, “Y” or “Z” axis
