A feature-based inspection process planning system for co-ordinate measuring machine (CMM)

“…More effective inspection preparation is required to reduce the inspection time [23]. Many researchers have focused on reducing the number of points for CMM measurement and better path planning in order to reduce inspection cycle time [23,24]. For this experiment, the inspection time of CMM and LR was 40 and 6 min respectively.…”

The increasing interest towards intelligent systems has led to a demand for the development of zero-defect strategies, with a paradigm shift from off-line and dedicated to inline metrology with integrated robotic systems. However, a major barrier preventing the systematic uptake of in-line metrology is the lack of evaluation of system capability in terms of accuracy, repeatability and measurement time, when compared to the well-established coordinate measuring machine (CMM). In this study, a robotic Laser Radar (LR) solution is assessed in the context of automotive dimensional inspection of Body-In-White (BIW) applications. The objective is both to understand the effect of robot re-positioning error on measurement accuracy and repeatability and to compare measurement results against a CMM. Eighty-one surface points, six edge points, twenty-five holes and sixteen slots were selected from an industry standard measurement plan. Whilst LR exhibits a lower measurement accuracy than twin-column CMM, its repeatability is well within the specification limits for body shell quality inspection. Therefore, as a real-time in-line metrology tool, it is a genuine prospect to exploit. This research makes a significant contribution toward in-line metrology for dimensional inspection, for automotive application, for rapid detection and for correction of assembly defects in real time, with subsequent reduction of scrap and number of repairs/re-works.

“…Moreover, techniques such as fuzzy set theory, Hammersley's algorithm, Zmap, etc., have been implemented by Cho et al [14] to determine number of measuring points, their locations, and optimum probing paths as well as possible collisions during the inspection run. Zhang et al [15] described inspection process planning system to produce an inspection process plan directly from the CAD model. This system comprised of five basic modules: tolerance feature analysis, accessibility analysis, clustering algorithm, path generation, and inspection process simulation to finally generate inspection plan for CMM.…”

Coordinate-measuring machines (CMMs) have widely been utilized for performing inspections due to its high precision and accuracy. With increasing complexities of parts and tighter tolerances, there is a need of well-defined strategies and techniques to effectively plan inspection process for CMMs. The proposed work comprehensively describes different steps to generate an instruction file which can finally be executed on CMMs for efficient measurement. This work which commences with feature extraction and recognition followed by generation of probe approach directions for accessibility, setup planning to get part orientation, determination, and distribution of touch points on features including other activities leads to an effective inspection plan. The inspection plan is then used to produce DMIS file which after post-processing is executed on CMM. A series of techniques and algorithms such as clustering algorithm, graphical method, artificial neural networks, and algorithms for generation of touch points have been utilized to accomplish efficient inspection on CMM. The effectiveness of proposed strategies and techniques has also been verified through a part case study.
