Increased Automation in the manufacturing sector with the introduction of low cost embedded systems and servo drives has resulted in a substantial increase in the precision and speed of packaged goods output. This increase in speed has rendered manual verification incapable to keep up. Recent developments in the area of computer vision and embedded computing has allowed for replacement of tradi...

Non-Newtonian Fabrics are produced from Polymerization of Terephthalic Acid and Etylene Glycol. In view of manufacturing defects, the finished products are sold at a massive discount of 45%-65%. Presently manual inspection is being done, where an expert inspector detects only 70% of defects. Here, we are simulating automatic defect detection of fabrics by means of using computers. We proposed t...

Semiconductor manufacturing industry is moving into the production of 300-mm wafers. To solve the increased workload problem in manual wafer handling, some personal guided vehicles (PGVs) have been developed to help in the transfer of front opening unified pods (FOUP). This study compares two kinds of PGVs with a traditional cart and evaluates the feasibility of using them for manual FOUP handl...

With an increased use of composite materials within the aerospace industry follows a need for rational and cost-effective methods for composite manufacturing. Manual operations are still common for low to medium manufacturing volumes and complex products. Manual operations can for example be found in material handling, when picking prepreg plies from a cutter table and stacking them to form a p...

Manual operations feature prominently in the manufacture of many electrical machines. Even though high-volume machine is dominated by automation, several manufacturing continue to involve manual intervention because complexity such makes them heavily reliant on high dexterity skills and experience. However, quality can be variable due human involvement. Currently, order maintain a precision con...

Manual assembly operations are sensitive to human errors that can diminish the quality of final products. The paper shows an application reliability analysis in a realistic manufacturing context identify where and why manual occur. techniques SHERPA HEART were used perform reliability. Three critical tasks selected for based on records: (1) installation three types brackets using fasteners, (2)...
