In present, the DBB(Double ball bar) measurement system which measure the motion error of multi-axis Machinine Too1s was in the limelight of machine tools industary. This DBB measurement system was more easier to using and more complexible to apply than the other Measure system(Grid encoder, Laser measurement system, Direct test). DBB measurement system will be secured reliability by The direct cutting test which is tested by machining the workpiece.
