Abstract
The measurement of helicoidal surfaces is very important for the manufacture and utilization of fine mechanical parts. It usually employs the feature line error to represent the helicoidal surfaces' error. Two methods, commonly used to assess the character line error, least-square method and accumulative sum method, are analyzed and compared here by combining with practical data processing.
