A Collaborative Framework for Integrated Part and Assembly Modeling

Abstract

An ideal product modeling system should support both part modeling and assembly modeling, instead of just either of them as is the case in most current CAD systems. A good basis for such integration is multiple-view feature modeling, as it allows focusing on different aspects of the product, while at the same time maintaining the consistency among all model views. This paper presents a framework that supports synchronous collaborative sessions via the Internet, among members of a distributed development team, with such a modeling system. The framework provides facilities for creating a hierarchical product structure, with single and compound components, and meanwhile assigning tasks to team members. The actual design of a single component is supported by a web-client specialized in part design, whereas the specification of assembly relations among components is supported by a web-client specialized in assembly design.All clients make use of the same server, which runs a multipleview feature modeling kernel and maintains the complete product model, guaranteeing the consistency between the part design and the assembly design views. In addition, the server keeps all clients up to date and manages all communication.

Step Pdm Schema Based Product Structure Manager For Collaborative Assembly Modeling

“…The note discusses the possibilities of conceptual, capability and accuracy mismatches for the model during data exchange process. Rafael Bidarra et al [16] proposed a collaborative framework for integrated part and assembly modeling over Web. The framework provides facilities for creating hierarchical product structures with single and compound components.…”

The Structure Design and Numerical Simulation of Internal Flow Field with High Efficiency Low Resistance Cyclone

“…The design of a high efficiency and low resistance cyclone dust collector, use 360° spiral parallel entrance structure. Because the gas from the air into the duct width into the spiral cyclone narrows gradually, reduces the risk of dust directly into the exhaust tube, improve the collection efficiency [4]. The reflecting plate cone cyclone is to prevent the dust with a central flow to mix on the back, the lower end of the conical cylinder exhaust tube to prevent the intake airflow directly into the exhaust tube and decrease the capture efficiency; exhaust tube is arranged in the resistance reducing guide plate, rotating speed to reduce the flow in the exhaust tube.…”

Applied Information Technology in KBE Based Intelligent Design System for Tricone Bits

“…The overall framework of MenuScript, UIStyler module development system supplied by NX as shown in Figure 3, the man-machine dialogue interface as shown in Figure 4, the drill bit design process of intelligent, visualization, human-computer interaction, guide the design personnel in accordance with the design process to complete the drill bit [4].…”
