Abstract This paper proposes a manufacturing technology plan based on the combination of 3D printing and precision cutting for certain projectile fairing part with thin-walled cavity structure. By holistically taking into account process design requirements, one hand, structure required is incorporated original to improve manufacturability parts; other comprehensive research plan, processing st...

Process planning in manufacturing today focuses on optimizing the conflicting targets of cost, quality, and time. Due to increasing social awareness subsequent governmental regulation, environmental impact becomes a fourth major aspect. Eventually, sustainability ensures future competitiveness. In this paper, framework for sustainable is proposed. It based abstraction generalization resources p...

In manufacturing, features can simply be defined as a geometric shape and its corresponding manufacturing information to create the intended shape. For the generation of process plans based on manufacturing feature, it is normal to expect that the corresponding manufacturing information will reflect the knowledge of process planners. This paper proposes a feature library that is able to manage ...

Hot forging is a common manufacturing process for the production of large quantities of engineering components. Residual stresses are developed in forged components as a result of various aspects of the manufacturing process, including subsequent cooling, and heat treatment. Residual stresses can significantly affect the deformation and fatigue failure of materials. Hot forged EN15R steel bars ...

science and technology world is using computers in different branches as much as possible. virtual reality has variety of application in different engineering fields. simulating softwares increase the accuracy and process speed of analysis. in this research the aim is to use this concept through milling process on cnc machines, so the students can learn objects effectively and eagerly. the appl...

Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task. Process planning is a...
