Conversely, if this change will definitely affect the existing design, pause the design and discuss it with the designer or system engineer who made the change. The whole process emphasizes that the designers decide the workflow themselves, and the decision-making power of the process is given. Designers increase the flexibility and design efficiency of the design process and ensure the quality of the design.

4 Conclusions Ten theories used to guide the optimization of design rogue. The design relationship matrix and workflow proposed by Muwen help to improve the engine design process from the perspective of ensuring reliable transmission of design information. The practical application proves that this is a simple and practical design process reengineering technology.

71 Vehicle wheel-to-counter wheel CNC lathe successfully developed Jiangxi Zhongji Technology Industry Co., Ltd. Nanchang High-tech Industrial Development Zone successfully developed the vehicle wheel-to-roller CNC lathe, and passed the final acceptance of Guangzhou North Vehicle Section of Guangzhou Railway Engineering Company And the province's new product identification. This product belongs to the national major technical equipment project railway vehicle wheelset CNC machining series machine tool equipment, with the international advanced level in the late 1990s. It fills the domestic gap.

The machine is driven rigidly with a pendulum. Smoothly solved the problem of machining the wheel rim tread without removing the wheel bearing and the end cap. This kind of vehicle wheel-to-roller CNC lathe is a high-tech numerical control equipment specially designed for railway city subways and elevated light rail vehicles. The products are mainly used for processing and repairing rims and treads, 32., 2826 railway 2 hard trucks With shaft and end 1; drop wheel pair. This kind of machine tool creatively uses the wheel drive technology, which drives the pendulum to transmit the power source to the drive wheel, and drives the wheel set by friction. The machine tool numerical control system controls the shape of the left and right tool holders to simulate the opposite edge of the wheel and the tread. During the processing, the anti-slip device implements the monitoring of the rotational speed of the wheel pair. The detection system promptly raises an alarm and outputs information before the slippage has not increased to the allowable value, and the data is fed back to the system for speed regulation, so that the wheel pair cutting returns to normal.
