abstract
The design framework of intelligent sheet metal forming database system concept is put forward, which allows technical design experts without process control system and experts with forming process experience. In this study, the proposed frame is a circular cup drawing applied to variable blank holder force (BHF) control technology. The system can be used for three typical process requirements, namely, uniform cup wall, improving cup height and energy-saving objective function. The experiment of aluminum alloy plate is also verified in this design framework.

Some research reports on optimal control of metal forming process have been completed and are developing towards intelligent methods. Sheet metal stamping and intelligent drawing technology have developed to the latest action. One method is fuzzy inference adaptive control method (BHF) based on BHF. The other is the control method and artificial neural network (ANN)[2 model] in the process of detecting plastic deformation and friction materials. Although they have good advantages, each control system needs a lot of time to design and develop processes and labor. First of all, the design engineer must be an expert with knowledge and experience of molding technology, otherwise the assistance of engineers and craftsmen is essential. Therefore, it is necessary to establish a new concept of process design.
Architecture can avoid the need for experts. Generally speaking, the formation of units and systems must be effectively designed in process design and process control. In the previous system, as shown in the figure. 1 (left), the role played by experts is the core number.

He also gained the necessary experience as an engineer and knowledge transfer experience. Over the years, the number of experts has gradually decreased. Therefore, in the future system, the process conditions must be automatically optimized with the help of experts. The purpose of this study is to
We can rely on the freedom of engineering experts, from the intelligent design and architectural design stage of process control, with the assistance of experts without knowledge of process design and control design and development.
A New Intelligent Process Design and Its Application
Its system architecture
Our concept map shows that. 1 (right) involves replacing the brain function of experts with a processor including an analyzer, a database and a knowledge base. The processor can design and control the process according to rules, databases and knowledge bases and a set of suitable algorithms.
In this process, remote sensing information from formed cells is stored, which is similar to the experience of experts. In other words, it can increase the acquisition experience: in an expert way. Therefore, it is suggested that the system can automatically optimize the process without any auxiliary operation.
Expert.
Figure 2 shows an overview of the system architecture based on the above concepts. It can be roughly divided into two parts. One is the processor, the other is the formation of cells and systems. The process of cell formation is provided by multiple sensors, actuators and information processor of Joni Joni Aho.
Commands from the processor. The processor consists of a database, a knowledge base and analysis (a design support tool for business control, using MATRIXX). Database and knowledge base, including process.
In the information and design process under various conditions, different methods are adopted. The processor can not only design the database and knowledge base used in the process, but also determine the remote sensing information of the material characteristics used by the workpiece and the control driver.
Sensor. In addition, the system can use database and knowledge base to deal with the changes of various workpieces and their materials, tool conditions and lubrication conditions.
Application of Deep Lottery Process in Architecture
In this study, the drawing problem of round cup is a basic and important demonstration role of forming with sheet metal. In the process of deep drawing, the forming limit is mainly the flange part affected by the fracture and wrinkling of stamping shoulder. Although it is necessary to apply BHF
In order to avoid wrinkles, excessive BHF leads to fractures. Therefore, it is necessary to successfully carry out proper BHF. Therefore, the blank holder force exerted by the newly designed frame is adaptively controlled in the drawing process to verify the usability of the frame. Figure 3 shows the design.
Metal and database formed in the process of intelligent system architecture. In this system, hzzy reasoning is selected as an artificial intelligence tool for process control design.
