At present, a considerable number of enterprises in China have purchased CNC equipment, such as CNC lathes and machining centers. Through research, analysis and comparison, it is not difficult to find that for most of the current CNC machine tool manufacturers in China, the general application level is not high, the production preparation (the preparation of NC programs and machine tools) has a long period, high error rate, and CNC machine tools. Functions, especially the development and application of special functions, low utilization of machine tools and other issues.
For the reasons, we believe that the following issues are worth discussing and urgently need to be resolved:
First, the operation level is low:
 In fact, the domestic manufacturers in the process of purchasing CNC machine tools, especially imported machine tools, have very high requirements for the technical and advanced nature of CNC machine tools, especially the numerical control systems. The selection of the functions of CNC machine tools is also very particular, and strives to become more and more effective. it is good. However, after the equipment is installed and operated, its use effect is not ideal. Operators' operations on CNC machine tools are limited to the level of training they receive and even lower. The use of the standard functions of CNC machine tools is insufficient, and the use of special functions cannot be discussed. The reason is mainly that the operators, programmers, and maintenance personnel have not learned enough about the basic theory of CNC technology, and the understanding is not deep enough. The improper management, the responsibilities of the relevant personnel of the equipment are not clearly defined, and the maintenance capability and level of the equipment are also important factors. As a result, operators are under pressure from the psychological pressure to take responsibility.
Second, low programming level:
CNC machine tools are only a flexible, flexible production tool, in order to play its characteristics and advantages, especially the powerful support of CNC NC programs. At present, most manufacturers of CNC machine tools in China are still using manual NC code input methods on CNC machines. Even if the programming environment of APT language has been configured, it will be discarded because of the complexity of its operation. For users who purchased various CAD/CAM systems, their operating environments are mostly limited to workstations. Even if the operating environment is on a microcomputer, they are all installed and operated in the product design department. Due to the ownership problems of CAD/CAM systems and the disconnection of design and production department management, the CAD/CAM system cannot be fully utilized in actual production and processing or the NC program prepared by the design department is not optimized according to the best process. Processing program. As we all know, for the shaft parts, NC programming of sheet metal parts is relatively simple, manual programming can be completed, and for the box parts, especially the complex profile, irregular space surface, rely on The human brain can't even imagine it, and then go to manual calculations and rely on artificial NC programming. The result is self-evident. Therefore, automatic programming of CNC machine tools is particularly important.
Third, backward tool management:
As an important auxiliary tool for the participation in manufacturing activities, the cutting tool system plays an important role in the flexibility and productivity of CNC machine tools and the precision and correctness of product manufacturing. At the same time, cutting tools are relatively expensive and expendable resources. In the more production environment of numerically-controlled machine tools, the number of cutters is huge, and the components therein are also quite complicated and the information is numerous. Due to the needs of production and processing, a large number of tools frequently flow and exchange between tool magazines and machine tools, and between machine tools and machine tools. . The traditional tool management is to record the information of the tool on the paper or remember it in the human brain. The time is longer and the recorded information is easily lost. The information of the tool is not easily grasped by different users, and the information management of the tool cannot keep up. The use of tools is confusing, resources are wasted, and production efficiency is low. More serious results are caused by excessive deviations in products, process deviations, and even product scrapping, which affects the production cycle. Establishing a complete tool database, incorporating all the information of the tool system into the computer for management, and establishing a paperless tool management system are imperative.
Fourth, insufficient understanding of the integrated management of CNC machine tools:
The promotion of CNC machine tools in China has been used for nearly two decades. At present, it is mainly focused on stand-alone use. After accumulating certain experience in stand-alone use, it has a single machine tool and external computer for users with multiple CNC machine tools. Or there is little information exchange between different numerical control machines. The exchange between NC NC programs and machine tools, from the original paper tape reader, to the use of a floppy disk drive, an NC program stored on a floppy disk.
The latest development is the direct connection between the external computer and the CNC machine through the serial port of RS-232C, and the direct and accurate transmission of the NC program. The external computer can be connected with multiple CNC machines with the same or different control systems. , Information sharing, and can manage the information in the production process of the numerical control section composed of multiple machine tools to reduce production preparation, especially the NC NC program preparation time. With the maturity of CAD/CAM, integrated management software, and the increasing demand for flexible manufacturing systems, the use of CNC machine tools, from stand-alone use to computer integrated management, is the direction of technological development in the production and processing industry.
It is based on the above mentioned problems in the mechanical processing industry, and the introduction of new concepts and concepts in CAD/CAM systems, the continuous introduction of MIS systems and ERP systems, and the further development of CIMS technology in China. The information integration at the bottom of the workshop is important. The weight. For this purpose, we have designed and developed various products described below for the integration of workshop processing equipment.
