Paper Abstract
Traditional methods of measuring out-of-squareness of ultra-precision motion stage have many limitations, especially the
errors caused by inaccuracy of standard specimens, such as bare L-square and optical pentaprism. And generally, the
accurate of out-of-squareness measurement is lower than the accurate of interior angles of standard specimens. Based on
the error separation, this paper presents a novel method of out-of-squareness measurement with a polygon artifact. The
angles bounded with the guideways and the edges of polygon artifact are measured, and the out-of-squareness distraction
is achieved by the principle that the sum of internal the angles of a convex polygon artifact is (n-2)π. A out-of-squareness
metrical experiment is carried out on the profilometer by using an optical square brick with the out-of-squareness of
interior angles at about 1140.2 arcsec. The results show that the measurement accuracy of three out-of-squareness of the
profilometer is not affected by the internal angles. The measurementwith the method can be applied to measure the
machine error more accurate and calibrate the out-of-squareness of machine.
