This paper outlined a feature-based inspection process planning system for co-ordinate measuring machines (CMMs). The inspection process planning system is designed to produce an inspection process planning directly from CAD model. The prototype inspection process planning system includes ®ve functional modules: the tolerance feature analysis, accessibility analysis, clustering algorithm, path ...

The process of vehicle inspection in the United Arab Emirates has been investigated in this study using multiple decision-making criteria. The objective was to assess the current situation and set out recommendations to improve vehicle inspection procedure. Inspected mechanical and environmental parameters have been compared among different inspection centers in the country. The assessment incl...

one of the most crucial elements of each country is electricity distribution networks (edn). awareness of accidents in edn could be very important in the conservation and utilization of them. the accurate and periodic inspections can provide a good service to subscribers. the goal of this project is to fabricate a quad rotor, which can do an accurate and a periodic inspection. the design and im...

a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

At present, the image quality of LCD panels has been determined subjectively by human visual inspection. In fact, the inspectors need to memorize a large number of instructions. The inspection tasks include a series of complicated procedures that increase the workload of the inspectors. This research focuses on the improvement of LCD inspection. The knowledge extracting of inspection data was t...

CCC-r chart extended approach of CCC charts, is a technique applied when nonconforming items are rarely observed. However, it is usually assumed that the inspection process is perfect in the implementation control charts imperfect inspections may have a significant impact on the performance of the control chart and setting the control limits. This paper first investigates the ...

Abstract Designing appropriate quality-inspections in manufacturing processes has always been a challenge to maintain competitiveness the market. Recent studies have focused on design of in-process inspection strategies for assembly based probabilistic models. Despite this general interest, practical tool allowing assessment adequacy alternative is still lacking. This paper proposes framework a...
