CAM and CNC machining In the process of using CNC equipment, the author has a certain understanding of the application of CNC machine tools, how to maximize the processing efficiency of CNC machine tools, I feel that there are some problems that must be solved.
(1) At present, the grassroots technical cadres and management cadres in enterprises, especially in state-owned enterprises, do not understand the principles of CNC machine tool processing and the characteristics of CNC systems, and are unfamiliar with the processing of parts processing procedures and procedures, and cannot scientifically manage CNC equipment. . Advanced processing methods and backward management methods have greatly affected the efficiency of CNC machine tools.
(2) Most of the CNC machining operators are from ordinary machining workers, and the cultural quality is uneven. In the application of numerical control equipment, the idea of ​​ordinary equipment processing is applied, the characteristics of high-speed cutting of CNC machine tools, the selection of CNC tools, and cutting parameters. The choice is not scientific, the quality of the processing program and the processing efficiency are completely dependent on the quality of the operators, and the processing efficiency of the numerical control equipment cannot be maximized.
(3) Due to specific reasons, the system of CNC equipment is complicated and the equipment is not well graded, which brings great difficulties to the application and programming of technicians and operators, which greatly limits the transfer processing of parts.
(4) The general system memory capacity is not very large. When there are many kinds of processed parts, a large number of processing programs have to be repeatedly deleted and typed because they cannot be stored, and limited system resources sometimes cannot even store a complete complex part. Processing program. Frequently repeated parts preparation wastes a lot of work time and directly affects the efficiency of CNC machine tools. Repeated programming of the machining program also affects the stability of the program.
(5) Since a large number of processing programs are manually programmed, it is difficult to ensure the accuracy of the calculation of complex surfaces, and it is difficult to ensure the processing requirements of parts and even waste products.
(6) Most of the enterprises have established their own local area networks, and CAD/CAM software is widely used in computers. Now enterprises are gradually implementing the CIMS management system, but the grassroots lacks links with the upper technical departments, so technology cannot be obtained. Strong support from the department.
The author believes that if you want to truly play the high efficiency of CNC machine tools, you must start from strengthening the management and popularization of CNC machine tools to the application of CNC machine tools.
(1) It is necessary to conduct high-quality training and examinations for grassroots technical management cadres, so that grassroots technical management cadres can truly understand the processing principle of CNC systems, numerical control processes and the preparation of numerical control procedures.
(2) Change the operation mode of the CNC machine bed machine, and carry out comprehensive network management of the CNC machine tool.
(3) At the end of 2000, we cooperated with the company and installed and used the CNCLINK3.0 CNC program automatic management system developed by the company to carry out remote network management of the CNC machine group of our factory.
The system uses the server to provide a huge program storage space for each CNC machine. The machine operator can browse, create, edit, delete, upload and download all the machining programs on the machine side. Significant savings in processing time wasted due to repeated programming and typing. It can also share the program stored in the server between the various machine tools, which facilitates the transfer processing of the parts between the machine tools. At the same time, it also provides single-channel DNC processing, which expands the processing capability of CNC machine tools. The user management function of the software enables authorized technicians to input, modify and delete the NC program on the server side. The log query function automatically records the content and time of all machine-to-machine programs.
The networking of CNC machine tools also creates an interface environment for CIMS management with the upper layer network. It enables the technical management department to optimize the CNC machining process and precise machining program with CAD/CAM software and cutting database. The production management cadres can also use the management software to dynamically manage the production of numerical control equipment on the server or local area network, query the effective start-up time of the numerical control equipment, the daily processing quantity of the parts, the number of products qualified, the waste products, and establish the efficiency file of the numerical control machine tool. Monitor the implementation of production plans and schedule new production plans. (Finish)
Borax is the basic raw material for preparing boron containing compounds. Almost all borides can be prepared by borax. They have important and wide applications in metallurgy, iron and steel, machinery, military industry, cutting tools, paper making, electronic tube, chemical industry, textile and other departments.
Glass and enamel industry
Borax in glass can enhance the transmittance of ultraviolet rays and improve the transparency and heat resistance of glass. In enamel products, it can make the enamel not easy to fall off and make it have luster. It is also widely used in special optical glass, glass fiber, non-ferrous metal welding agent, jewelry binder, printing and dyeing, washing (silk and wool), gold refining, cosmetics, pesticides, fertilizers, borax soaps, antiseptics, antifreeze and medical disinfectants. [6]
Medical field
Borax is used for the treatment of skin mucosa, some tinea pedis, and also for the treatment of some inflammation, such as acute tonsillitis, pharyngitis, sore of mouth and tongue, gingivitis, otitis media, fungal vaginitis, cervical erosion, epilepsy, tumor, etc. It also has special effects in treating some animal diseases, such as chicken laryngotracheitis, goat infectious pustulosis, Mycoplasma suis pneumonia, and bovine chronic mucinous endometritis. Boron is an essential element for plant growth, human beings and animals.
Industrial field
In industry, borax is the most important industrial boron mineral. Borax is the most important compound of boron. Boron is often listed as a rare element in foreign countries, but there is abundant borax ore in China. Therefore, boron is not a rare element in China, but a high-yield element. In industry, borax is also used as a solid lubricant for metal wire drawing. It is often used as (inactive) flux to purify the metal surface in the welding maintenance of refrigerators, electric freezers, air conditioners and other refrigeration equipment. Remove the oxide on the metal surface; Add a certain proportion of sodium chloride to borax. Sodium fluoride, potassium chloride and other compounds can be used as active flux for welding between copper pipes and steel pipes and between steel pipes in refrigeration equipment.
