Automatic model generation, the consequential reduction of problem solving cycles and the need for a higher degree of data integration have long been characterized as significant challenges in the field of simulation of manufacturing systems. Especially operationally used manufacturing simulation models require a high degree of modeling detail and thus depend on a significant amount of input da...

During the product development, Automatic Feature Recognition (AFR) techniques are an important tool for achieving a true integration of design and manufacturing stages. In particular, AFR systems offer capabilities for the identification in Computer-Aided Design (CAD) models of high-level geometrical entities, features that are semantically significant for manufacturing operations. However, th...

Ordinarily, a robot workspace has insufficient room to allow the setup of multiple applications simultaneously. As a result, it is common practice to use modular fixtures which hold the workpiece while the robot performs one of the applications. When the product line is to be changed, the fixture is replaced. Doing this generally requires reprogramming the manipulator. When performing this repr...

There is a significant increase in volume and complexity of electrical wiring in today’s aircraft programs. This is illustrated by comparing the total wire length of the Airbus A380 (530 km [1]) with the Airbus A340 (300 km [2]) and the Boeing 747-400 (274 km [3]). The increase in volume is caused by the introduction of new electrical systems and the replacement of pneumatic and hydraulic syste...

Scheduling is an important tool for a manufacturing system, where it can have a major impact on the productivity of a production process. In manufacturing systems, the purpose of scheduling is to minimize the production time and costs, by assigning a production facility when to make, with which staff, and on which equipment. Production scheduling aims to maximize the efficiency of the operation...

The footwear industry’s need for an automatic containment algorithm is becoming increasingly important within the manufacturing process. Irregular containers, such as hides, have many different quality regions and holes that must be taken into account when containment is done because they represent an important cost. Automatic containment processes should be aware of these factors and still per...

The use of supervised pattern recognition technologies for automation in the manufacturing environment requires the development of systems that are easy to train and use. In general, these systems attempt to emulate an inspection or measurement function typically performed by a manufacturing engineer or technician. This paper describes a self-optimizing classification system for automatic decis...

During design and implementation of the automatic materials handling system (AMHS) for a local 300mm semiconductor wafer fab (semiconductor fabrication plant), we observed and found an interesting phenomenon Vehicle Clustering Phenomenon (VCP) from the dynamics of automated vehicles: As time evolves, the distance between any two adjacent vehicles usually becomes very close enough as if all the ...

Optimizing the manufacturing cost is critical in tolerance synthesis. Decreasing the tolerance range will improve performance but will also increase the manufacturing costs. It is desirable to optimize the tolerance range under such constraints of product design as the relationship between the dimensions of entities of a component and the functional requirement of the design. We propose a const...
