Articulated Arm Length Calibration for Cantilever Coordinate Measuring Machine

Abstract:

Cantilever CMM(short for coordinate measuring machine) is non-orthogonal type one with large measurement range, small volume, light weight, low cost, but lower precision. Error calibration and compensation is an important way to improve the measurement accuracy . This paper presents a new calibration method for the length of articulated arm just using the square. Facility requirement is relatively low and it is easy to operate. Comparing with that measured by laser interferometer, this method has a relatively high accuracy, having a certain value in practical measurement.
