Automated inspection planning system for CMMs

Abstract

Coordinate measuring machines (CMMs) have been recognized as a powerful tool for inspection and measurement purposes. Maximum utilization of CMMs requires the development of an automated inspection planning system. A computeraided inspection planning (CAIP) system leads to minimization of the total time needed for inspection process and hence the overall cost of the final product. This work introduces a computer aided inspection system that reads a B-rep solid model in SAT format as an input and produces the final CMM program in DMIS format. The system includes the following: rule-based feature recognition module that identifies and extracts the necessary inspection features from the solid model, sampling strategy module to determine the number and the location of the needed measuring points on each inspection feature, accessibility analysis module to determine the number of probe orientations that can reach the measured points without collision, finally, a clustering module to minimize the total number of probe orientations need to fully inspect the entire part. All algorithms are developed using ACIS geometric kernel and object oriented programming using C++. The results are verified on CMM.

Automated Coordinate Measuring Machine Inspection Planning Knowledge Capture and Formalization

“…The tolerance information, as input by the user, is combined with stored knowledge and a set of fuzzy rules to produce optimal measurement strategies. An automated CMM inspection planning system was introduced by Hussien et al [26] consisting of several rule-based modules for: feature recognition, sampling strategy, accessibility analysis and probe orientation clustering and minimization. The final output generates a Dimensional Measuring Interface Standard (DMIS) code for operating a CMM.…”

“…Concepts for the automatic inspection planning are presented in [19,20]; they could serve as a basis for development and implementation of optimisation models. The state of the art in inspection planning is given in [21], whereas trends in development of the production metrology in intelligent manufacturing are shown in [22].…”
