This article describes an automatic plate aligning and orthogonality test to determine if a machine can meet certain squareness specifications. The test is run by a program which replaces the manual test of plate alignment and machine orthogonality. The aligning of a five-pin plate fixture, as illustrated in Fig. 1, by dial indicator of a performance measurement device is a procedure that is time consuming and prone to human error. The adjustment of the dial indicator for each pin and the remembering of the dial indicator readings is often tedious and inclined to error. Current methods require approximately 10 to 30 minutes to align a plate to the workspace. A manual orthogonality test requires a minimum of 25 minutes to run.
