Geometrical size examination method for drill hole, involves carrying out knowledge-based evaluation of standardized description values with respect to defined reference value, and deriving testing result from result of evaluation

摘要

#CMT# #/CMT# The method involves determining an emerging radiation pattern and an assigned data record. Changes to be made in the radiation pattern and the assigned data record are changed by defined statistic and geometrical procedures of image processing, into standardized description values. A knowledge-based evaluation of the determined standardized description values is carried out with respect to a defined reference value under an application of a central evaluation and control unit. A testing result is derived from a result of the knowledge-based evaluation. #CMT# : #/CMT# An independent claim is also included for a device for examination of geometrical sizes of drill hole in nozzles and similar hole courses in an assembly for guiding of flow media, comprising a test sensor. #CMT#USE : #/CMT# Method for examination of a geometrical size of a drill hole in a nozzle and a hole course in an assembly i.e. injecting assembly, for guiding flow media in an internal-combustion engine utilized in automotive technology. Can also be used for examination of a drill hole in a screen and a throttle point. #CMT#ADVANTAGE : #/CMT# The method enables effective examination of geometrical sizes of hole courses by the determination of reflection and diffraction behavior of electromagnetic radiation in hollow contours and at component edges and by the evaluation of parameters with reference values. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating a fundamental structure of test optics. 2 : Optical beam control 3 : Fixable uncoupling optics 4 : Assembly 11a : Z-axis 11b : Test light beam.
