One of the most basic concepts in geometric dimensioning and tolerancing is perpendicularity or checking for square. While this can be easily accomplished at the machine with the use of the machinist square being held up to the light, that method can only guarantee squareness to within .003" of an inch. Obviously many machined parts require a closer tolerance than that and we can set up a test using a surface plate, an angle plate, and a probe type indicator.
