A Reliable Method of Minimum Zone Evaluation of Cylindricity and Conicity from Coordinate Measurement Data [PDF]
, 2011 The form error evaluation of cylinders and cones is very important in precision coordinate metrology. The solution of the traditional least squares technique is prone to over-estimation, as a result unnecessary rejections may be caused.
