The ability of automatic fiber cutting machine to adapt to changes in processing objects

Taiwan group automatic fiber cutting machine entered the practical stage in 1955, and 100 sets of similar products were put into production. These CNC milling machines play a great role in the processing of complex curved parts. In 1958, the United States developed a machining center (automatic tool change multi-station machining CNC machine tool). In 1970, the United States developed DNC (Group Control System) direct digital control. Since then, with the rapid development of microelectronics technology, computer technology, information technology, and laser technology, the machine tool industry has continued to advance by leaps and bounds, and machine tool products have been constantly innovating. Nowadays, the development of CNC machine tools presents the following development trends: high-precision The positioning accuracy of the current CNC machining center can reach ±0.0015mm/full process; the machining accuracy of the machining center can reach ±0.001mm, or even higher. (2) High speed and productivity is one of the basic goals pursued by the development of machine tool technology. The most important and direct way to achieve this goal is to increase the cutting speed and reduce the auxiliary time. Increasing the spindle speed is the most direct and effective way to increase the cutting speed. With breakthroughs in key technologies such as cutting tools, motors, bearings, and numerical control systems, as well as the advancement of the basic technology of the machine tool itself, the spindle speed has doubled in the past ten years. At present, the spindle speed of the machining center is higher up to 50000r/min, or even 100000r/min. In addition, further increasing the feed rate, shortening the tool change time and workbench exchange time are also effective measures to increase the speed. High flexibility 'Flexibility' refers to the ability of a machine tool to adapt to changes in processing objects (flexibility, versatility).

The traditional automatic equipment and production line of the group automatic fiber cutting machine are mechanically or rigidly connected and controlled. When the processed object is changed, the adjustment is very difficult, even It's impossible, and sometimes you have to replace and update all of them. The emergence of CNC machine tools opened a new era of flexible automated processing. It has strong adaptability to the transformation of processing objects, which is very suitable for single-piece and small-batch production. The conversion of parts only needs to replace the control program in ROM, and the machine tool and hardware do not need to be adjusted. In order to further improve the degree of flexibility and large-scale production capacity, on the basis of the software and hardware of the CNC machine tool, add different capacity tool magazines and automatic tool change manipulators, increase the second spindle, increase the exchange table device, or be equipped with industrial machines. There is a strong question among readers: Is this kind of collaboration possible with smarter technicians? In other words, for some workers who are better at making judgments, can these people choose a more scientific and perfect method out of their own will? The following will exemplify: In more types of work, the scientific laws to be formed are very profound. When a skilled worker with a higher salary level explores these laws, and selects, develops and trains him to act according to these laws, he needs more (more than the salary level). Lower workers) than those with a higher level of education. These examples clearly illustrate the original hypothesis: in all craftsmanship, the science that is the basis of each worker’s behavior is so profound that even if he is competent for the actual work he is engaged in, due to lack of education or insufficient intelligence, Can't understand this science either. For example, there may be such a question in the minds of most readers: In a situation (a company produces the same machine in large quantities year after year, in such a production process, each technician repeatedly enters a limited amount of Group operation), each worker’s intelligence and the help he receives from time to time from his team leader, can’t it be possible to form an advanced method and personal skills (although scientific research on this is not yet possible), so as to actually improve the work Is it efficient? Many years ago, there was a company employing 300 workers and it had been manufacturing the same machine for 10-15 years. They asked me to give a report to see if the introduction of scientific management can bring some benefits to the company.
