Spatial measurement accuracy tests of the laser ball bar. Final report

PDF Version Also Available for Download.

Description

A series of tests were performed to evaluate the spatial and length measurement accuracy of the LBB. The length measurement accuracy tests consisted of using the initialized LBB to measure the distance between two magnetic sockets. While the LBB was installed in the sockets, the M-60 probed the spheres at the LBB ends and computed their coordinates. The deviations between the LBB predicted length and the M-60 predicted length ranged from +56 to {minus}21.5 {mu}in. The mean value of the length measurement errors was +21.5{mu}in. with a standard deviation of 10.5{mu}in. The spatial measurement accuracy test consisted of commanding the ... continued below

The length measurement accuracy tests consisted of using the initialized LBB to measure the distance between two magnetic sockets. While the LBB was installed in the sockets, the M-60 probed the spheres at the LBB ends and computed their coordinates. The deviations between the LBB predicted length and the M-60 predicted length ranged from +56 to {minus}21.5 {mu}in. The mean value of the length measurement errors was +21.5{mu}in. with a standard deviation of 10.5{mu}in. The spatial measurement accuracy test consisted of commanding the M-60 to move to selected points in its workspace. and using the LBB to measure the coordinates of these points. The LBB measurement error is defined as the difference between the LBB predicted coordinates and the commanded coordinates. The data were normalized to a point which was in the center of the measurement zone (i.e. the LBB coordinate system is assumed to be coincident with the M-60 coordinate system at this point). Three complete sets of measurements were taken. The range of LBB measured coordinate errors over the three data sets was +32 to {minus}47{mu}in. in X, +59 to {minus}21{mu}in. in Y, and +36 to {minus}47/{mu}in. in Z.
