The storage space is small, the number of storage programs is small, and a large number of them need to be re-commissioned and modified; Yantai Ice Wheel Co., Ltd. is a listed company specializing in the production of refrigeration and air-conditioning equipment. Due to the high technical content and complicated process of the products produced, a large number of CNC machine tools have been introduced. With the increase of CNC machine tools, how to strengthen their management and maximize their economic benefits has become an important issue for the company. After many investigations, the company finally cooperated with Beijing Languang Innovation Technology Co., Ltd. to introduce the world-leading aivCODNC-Mbx CNC machine tool networking system, successfully connecting all CNC machine tools into the company LAN, forming a network management and greatly improving The management level has laid a solid material foundation for the company's information management.
Problems existing before a network The existing CNC system is complicated, and the communication protocols (baud rate, data bits, stop bits, parity, start and end characters, etc.) used between the systems are different from the communication cable. The status quo is incompatible with each other; using a laptop to transfer programs, frequent hot plugging is very easy to burn out the machine interface; program transfer requires the programmer and the operator to complete together, very inconvenient; the processing program has to be repeated Deletion and typing, wasting a lot of working time, directly affecting the processing efficiency of CNC machine tools; there are several older machine tools that have not been able to achieve automatic transmission of the computer because they cannot find the corresponding communication data, so they have to type manually. Errors and wasted time; one originally used a dedicated floppy disk drive to transfer the program, but because the floppy disk is easily damaged, the program is often lost and management is inconvenient.
Due to inconvenient transmission, many programs are currently available on the control panel. Due to small memory and misoperation, the program often loses and the management is confusing. Some programs are saved on the computer through transmission, but generally only files can be used. The way of saving clips often takes a lot of time to find programs. It is easy to cause confusion when different versions of programs are saved. The programs on the computer and the process cards, tooling files, tool lists, etc. are stored in isolation. It takes a long time to be confirmed. Their correspondence has caused great trouble to the application; since the machine tool and the computer cannot communicate in real time, there are many programs programmed on the computer that cannot be updated in time after debugging changes on the machine. The computer still stores the old version of the program. The next call is due to the lack of permission to manage the NC program, the program often changes, and the modification cannot be traced.
Editing and editing of the program is generally done on the control panel or in the notebook of the computer. Since there is no dedicated numerical control programming tool, the modified program cannot be compared, simulated and automatically backed up. Frequently, some unexpected errors occur. It was discovered only when the machine was verified.
In response to the above problems, after communicating with the technical staff of Beijing Languang Innovation Technology Co., the following machine tool networking method was finally adopted. The structure of the system and the topology of the network are shown in Figure 2. The following is a description of the program.
The entire network is based on the company's existing LAN, and a normal HUB is placed in the production workshop, and a MOXA single serial server is installed in each machine electrical cabinet. The serial port of the serial server is connected to the HUB through a shielded twisted pair cable, and the serial port is connected to each machine through a serial line. One PCm in the workshop office serves as the dMCC-DNC server, and each client is expanded in the process group and the workshop.
The NC program management system is composed of these three parts seamlessly integrated into one unit, which is responsible for machine tool communication, program editing and program management. The program simulation verification expert MCUV2 directly performs physical simulation on the G code.
☆Implemented the CNC machine tool network, long-distance communication, completely get rid of the manual or single machine entry program; ☆ remote call function allows the operator to get the list of programs on the server directly on the machine control panel, and can directly call ☆ ☆ program needs to be uploaded from the machine tool to the server, the server can automatically receive, and naming, saving and backup of the program, no need to be on duty; ☆ multiple machines can upload and download at the same time, do not affect each other; ☆ each transmission It can generate success/failure reports, and feedback the transmission status to the operator in time; ☆ transmit the record, record the daily transmission situation, and facilitate the administrator to understand the on-site production information; ☆ Any PC on the network node can browse the server through IE. To the machine switch status and communication situation at the production site, the program operation can be understood through special macro instructions; ☆ provides an efficient platform for program editing, modification and simulation. The program is used in front of the machine tool, using its trajectory and physical simulation functions. Rehearsal, greatly reducing the situation of batch scrapping of parts; ☆ realized CNC The database management of the order overcomes the drawbacks of the folder management method; ☆ can manage various information of the NC program, such as program number, nickname, part number, machine tool and user information, and can customize the key field; ☆Can search for the program number, nickname, machine tool, operator and programming time, and support the wildcard, so it is convenient to find the desired program; ☆ program as the main line, related to the program Program remarks, tool list, craft card, blank 圄, tooling ç‰ and other information for related management, all information in the same interface of the database, at a glance, provides a platform for the paperless operation of the workshop; ☆ to achieve strict Rights management, different personnel have different management rights; ☆ The program is divided into three states of editing, debugging and stereotypes, strictly in accordance with a series of process operations such as preparation, auditing, on-site verification, approval, etc., to ensure the accuracy of the program; Management has records and traceability; ☆ provides a smooth flow for operators, programmers, and managers. The information exchange platform enables them to complete the preparation, modification, review, verification, approval, invocation and backup of the program without leaving their own office environment.
After the realization of the numerical control machine tool networking, the Yantai ice wheel completely changed the original numerical control management mode, which greatly improved the communication efficiency of the machine tool. Especially in the trial production process of new products, it has played a role of high programming efficiency and rapid verification, which greatly improved the efficiency of trial production. Program management is gradually systematic and standardized.圄3 and 圄4 are the use of CIMCO machine tools. Due to the systematic and standardized workflow, all kinds of personnel are properly configured, which avoids the push of people and greatly enhances the enthusiasm of employees. The high efficiency and accuracy of the program transmission greatly reduce the standby time of the CNC machine tool and the verification time of the program, reduce the scrap rate of the parts, and exert the greatest economic benefits.
The CNC machine tool network management system provides a link platform for the soon-to-be-built workshop production management system, equipment online maintenance system and the upper PDMERP, and has become an important part of the company's information construction.
