Precision On-machine Measurement Technology of Rotational Complex Aspheric Surface

Aiming at surface measurement difficulty for complex aspheric surface. Based upon the ultra-precision machine and precision trigger probe, it brings forward the contacting figure measuring principle by testing the meridian of aspheric surfaces and comparing it with the theoretical curve to get the surface figure error. The measuring experiments show that the measuring principle has high accuracy, universal utility, applied value and application prospect in the aspheric machining and measurement.
