|points per millimeter
The CMM controller samples points from an analogue probe at a fixed rate. If the scanning speed is faster than the maximum sample rate of the controller the resulting data is interpolated and may not be reliable. To maximize accuracy the scanning speed should not exceed the sample rate of the CMM controller.
This function calculates the signed difference between two points parallel to a specific vector. For PC-DMIS users this would be the same as the 'T' value.
This function calculates the distance between two points perpendiclar to a specific vector.
This function calculates the expected error when measuring a part on a CMM with an environment other than 20 C. One assumption is that the axis and part temperature are the same. The resulting error is absolute or unsigned. Note: This kind of error can be corrected using temperature compensation.
This function converts between azimuth/elevation angles and IJK vectors. The elevation angles are between -90 and 90 degrees. The calculated azimuth angle is positive between 0 and 360 degrees but signed azimuth input values are accepted.
