A method for studying 3d - scanned data with the use of parametric tolerance

摘要

It is a method for examining of 3 - d - scanned data with the use of parametric tolerances (t1, t2, t3) is made available. The method comprises a fixing (s110) a number of parametric tolerance - objects so that they are equal to the of permissible tolerances in the construction data (600) is an object to be examined, a link (s120) the construction data (600) of the object to be examined with the predetermined parametric tolerance - object, without the permissible tolerance for each region in the construction data (600) of the object to be examined to enter directly, and an automatic modifying (s180) of the permissible tolerance - value of the with the design data (600) linked range, when the parametric tolerance - value is changed. Consequently, not every a construction data - region corresponding tolerance - value as a whole, once again be reworked, if a region of the permissible tolerance corresponding to a design modification is changed. In the construction data (600), used in the permissible tolerance is classified and fixed as a parametric tolerance, and the construction data (600), with the according to the permissible tolerance classified predetermined parametric tolerance linked. The by means of a scanner (100) measured measurement data of the object to be examined and the construction data (600) are compared and investigated. Subsequently, a report is created (s170) or is ..
