Digital manufacturing non-business type

Digital manufacturing has matured applications in the process industry. However, in the discrete environment where the equipment industry is a single batch of small quantities, digital manufacturing is not difficult, but its development trend seems to be unstoppable.

Recently, Beijing Digital Digital Technology Co., Ltd. (CAXA) held a digital manufacturing user conference in Beijing. Lei Yi, president of the company, said at the meeting: “The Obama administration proposed reindustrialization during the campaign. Many people in Europe also advocated the third industrial revolution, and digital manufacturing became precisely the intersection of these two concepts.”

At this meeting, representatives from Sinosteel Xingji, Beijing Hangxing, Nanyue Electronic Control and Wuhu Impeller also introduced their respective explorations in enterprise informationization.

The practice of large state-owned enterprises

Zhao Fengrui of China Steel Xingtai Information Technology Department said: “At present, the network has covered every department of the company and every branch workshop, connecting more than 2,000 network terminals, including more than 120 cold processing equipment such as lathes, milling machines and grinding machines. 191 thermal processing equipment such as heat treatment."

The company is a wholly-owned subsidiary of Sinosteel Corporation. It has more than 7,000 employees and total assets of 5 billion yuan. Sinosteel Xingtai has advanced processes and equipments for smelting, casting, forging, heat treatment and mechanical processing. The production and sales of rollers ranks first in the world.

After establishing the strategic goal of "building the world's first strong enterprise in the roll industry", the company has fully launched the "three major technological reforms" project. Zhao Fengrui said that with the expansion of production capacity, in order to meet the needs of the company's multi-variety, low-volume production model, in the case of expanding the level of equipment, we must improve the utilization of high-performance equipment to achieve the networking and automation of manufacturing.

Sinosteel Xingji chose to cooperate with CAXA to implement a digital manufacturing project based on network DNC. In the past three years, Sinosteel Xingji has realized DNC communication with the company's internal two-factory and five-factory plants, including heterogeneous CNC machine tools, and it has also realized the automated collection of more than one hundred units of five-factories. Currently, it is still communicating with CAXA effectively and plans to collect the whole equipment of the second branch factory, and use the collected data as a whole in the whole process control system to realize the automatic transmission of the CNC machining program and the automatic operation of the equipment.

Zhao Fengrui said that after the project was implemented, the company's cold-worked hundreds of CNC machine tools were connected to the DNC. Through direct networking with the equipment, the automatic transmission of processing programs and process data, as well as the automatic collection of operating parameters of the hot and cold processing equipment were realized. Moreover, the system automatically dispatches the NC program to the corresponding machine tool, and the processing program is automatically distributed, which effectively improves the overall automated production level and greatly increases the production efficiency. This extensive application of networked production equipment in the equipment manufacturing industry in the non-automated product production line is a domestic advanced level.

Technology should continue to develop

Beijing Hangxing Machinery Manufacturing Co., Ltd. is a national large-scale second class military research and production unit affiliated to the Third Institute of China National Aerospace Science and Industry Corporation, a national first-class enterprise. Beijing Hangxing did not select CAXA at ​​first. Teng Yingjie, the company’s informatization chief, told reporters: “Initially, on the DNC system, we chose a mature communication partner. However, we hope to load more later. The company’s product structure data management capabilities make it difficult for this company."

Through his appearance, Teng Yingjie told delegates: “We choose suppliers not only to select large suppliers, but also to select suppliers with technological development capabilities so that it can provide you with appropriate support. We have been working with CAXA since 2008. In cooperation, we realized the on-the-spot data networking acquisition and workshop data centralized management of workshop machine tools, moved the production site operations to the computer desktop, and improved the workshop production process management level. In 2011, we expanded and applied the DNC system to realize the DNC system and The integration of PDM systems will form an integrated system for the entire enterprise.CAXA has ideas in digital manufacturing and its products are systematic. CAXA can provide them in the 12th Five-Year Plan when we build a digital manufacturing platform. Strong support."

Increased production efficiency

Nanyue Electronic Control Information Center Director Yang Zhibin said that the digital manufacturing project solved the company's four major problems. One is to solve the problem of not having a centralized NC programming and management system; the other is to solve the problem of lack of an effective system to monitor and collect the first-hand data of equipment operation; third is to solve the problem that there is no first production site. Hand real-time production monitoring data problems; Fourth, to solve the problem of on-site production of more auxiliary time, or more auxiliary positions.

In 1995, Nanyue Electronic Control was jointly established by Hunan Hengyang Auto Parts Factory and American Asia Strategic Investment Company. In 2010, the company successfully repurchased most of its shares and changed its name to Nanyue Electric Hengyang Industrial Technology Co., Ltd. The company mainly produces fuel injection systems and buybacks are for listing.

It is reported that in accordance with the company's digital manufacturing project implementation schedule, in 2013, all key processes of the company's CNC machining equipment will be connected to manufacturing, from 2014 to 2015, the company's 300 important CNC machining equipment will be connected manufacturing. At present, the company has 18 sets of CNC machining equipment and data precipitation for 20 sets of debugging equipment.

Yang Zhibin stated that since the project was implemented, the production efficiency and efficiency of related production lines have increased by more than 15%, and at the same time it has laid a good foundation for the implementation of subsequent MES and integration with ERP.

Private company boss's assistant

Different from previous speakers, Wang Hongqi's identity is not the head of the company's informatization department, but is the owner of the private enterprise—the chairman of the Wuxi Wuhu Impeller. His concerns are also different: "Sitting in the office, you don't have to look at statements anymore. When I click on a computer, at least I can know a few things. How many orders do customers give me? Do you want to buy equipment?"

Previously, subordinates often reported that orders had increased and they needed equipment. In 2011, the Penghu Impeller bought more than 30 million yuan worth of equipment, but the following still reflects that it is not enough. Wang Hongqi said: "I have no way to convince subordinates, just listen to them saying that the equipment is not enough, and then buy it, then I can only buy it. Now I said, I know how much your OEE (Equipment Overall Productivity) is, I don't need to tell you this, I can see it on the Internet. I tell them I don't care where your OEE is now, 30. 40 can be, but the problem you have to progress a little bit every month, can not say 40 this year, 39 next year, right?

“After we have installed the CAXA software, first, I don’t need so many people to count. Second, I can also know the correct number the first time. This is very good for the boss.” Wang Hongqi Told reporters.

CAXA Practice

Zhang Ziqiang, general manager of CAXA Development Department, briefed reporters on several successful cases. For example, Xikai Electric, a company that produces traditional high-voltage switchgear. Through the construction of the plant's Ethernet, layout collection terminal, to achieve the necessary control system code upload and control measures, production preparation time is greatly reduced. In addition, by analyzing the efficiency of the search equipment and the causes of the shutdown, the final production efficiency and output value of the workshop increased by 20%.

The second is the famous aircraft manufacturing company - Shen Fei. Because the numerical control equipment of the aviation company is used very early, and the numerical control equipment put into various periods is in service at the same time, it is necessary to provide its interface for the equipment of different periods including the communication protocol before it can be digitized. At the same time, aircraft manufacturing has very strict control over some processes in the management process because they are all single-piece processing and it is necessary to ensure that the procedures are accurate.

The third is the Zhengzhou Coal Machinery Co., Ltd., the largest coal mining machinery enterprise in China. The company's characteristics are that it involves a large variety of numerical control equipment and a large number of assembly lines. Through integration, it finally achieves unified operation.

The fourth is Ingersoll Rand, which is a joint venture that produces parts and components. The main effect of the company is to dig deeper into system efficiency through digital manufacturing. In the absence of increased investment in equipment, production capacity has increased significantly.

Obviously, digital manufacturing is a trend that has nothing to do with the type of business.
