virtual reality
Virtual reality technology is the use of sensory organization simulation equipment and dynamic model of real or virtual environment to generate or create the environment or reality that people can perceive, so that people can rely on intuition to act on the virtual environment of three-dimensional simulation model produced by computer. The first mock exam technology based on Vinual Manufacturing is to integrate design and manufacturing processes under a unified model. It integrates all kinds of processes and technologies related to product manufacturing in the three-dimensional, dynamic simulation of real process rhyme entity number model. Its purpose is to predict, test and evaluate the performance and manufacturability of products by means of modeling and simulation technology in the product design stage. So as to organize the production more effectively, economically and flexibly, enhance the level of decision-making and control, effectively reduce the backtracking changes brought by the early design to the later manufacturing, and achieve the minimization of product development cycle and cost, the optimization of surface grinder product design quality and the maximization of productivity.
Virtual manufacturing technology has fundamentally changed the traditional manufacturing mode of design, trial production, design modification and scale production. Before the product is really manufactured, the soft product prototype (s-pe) is generated in the virtual reverse manufacturing environment to replace the traditional hard prototype, and its performance and manufacturability are predicted and evaluated, so as to shorten the product design and manufacturing cycle, reduce the product development cost, and improve the system's ability to respond to market changes quickly. Virtual enterprise is to quickly respond to a certain market demand, through the information superhighway, the different enterprises involved in products are temporarily formed into a cooperative economic entity without walls, beyond the space constraints, relying on computer network connection and unified command. The characteristics of virtual enterprise are the incomplete function of the enterprise, the decentralization of the region and the non permanence of the organizational structure, that is, the virtualization of the function, the virtualization of the organization and the virtualization of the region.
Virtual manufacturing can be divided into design centered virtual manufacturing, production centered virtual manufacturing and control centered virtual manufacturing
(1) Design centered virtual manufacturing emphasizes the simulation, analysis and optimization of digital product model based on unified manufacturing information model, and the analysis of product structure performance, kinematics, dynamics, thermodynamics and assemblability, so as to obtain the design evaluation and performance prediction results of products.
(2) Production centered virtual manufacturing simulates the production process of an enterprise under the constraints of enterprise resources, and optimizes different machining processes and their combinations. It analyzes and evaluates the producibility of products, optimizes the combination of manufacturing resources and environment, and makes rational decisions on production planning and scheduling by providing accurate production cost information.
(3) Control centered virtual manufacturing, which introduces simulation technology into the control model, provides a virtual environment to simulate the actual production process, and enables enterprises to optimize the manufacturing process on the basis of considering the workshop control behavior.
