In recent years, features have been introduced in modeling and planning for manufacturing of parts. Such features combine geometric and functional information. Here it is shown that the feature concept is also useful in assembly modeling and planning. For modeling and planning of both single parts and assemblies, an integrated object-oriented product model is introduced. For speci"c assembly-re...

Signi cant advances have been made in the area of macro planning for assembly operations (i.e., dividing a product into sub-assemblies, determining the sequence of assembly operations). On the contrary, the state of the art in micro planning (i.e., tool selection, path planning for tool and part movements) is rather primitive. To generate a realizable assembly plan, both macro planning and micr...

Considering the present business competitive scenario, the automotive industry is under pressure to achieve higher productivity. A high level of performance and quality standard could be achieved through improving the Overall Equipment Effectiveness (OEE) of the equipment in an automotive industry. Thus, the aim of this study is to investigate the performance measurement through OEE theory in a...

Proper planning of assembly lines is one of the production managers’ concerns at the tactical level so that it would be possible to use the machine capacity, reduce operating costs and deliver customer orders on time. The lack of an efficient method in balancing assembly line can create threatening problems for manufacturing organizations. The use of assembly line balancing methods cannot balan...

Purpose – This paper aims to investigate automatic assembly planning for robot and manual assembly. Design/methodology/approach – The octree decomposition technique is applied to approximate CAD models with an octree representation which are then used to generate robot and manual assembly plans. An assembly planning system able to generate assembly plans was developed to build these prototype m...
