Large CNC gantry milling has occupied an important position in the machining equipment, with the continuous development of science and technology, the current large CNC gantry milling technology and equipment is already in the process of high efficiency, high security and intelligence, the future of large CNC gantry milling will be what kind of development trend?
1、the development trend of performance
Efficiency, speed and accuracy is the key performance indicators of machining, large CNC gantry milling using a high-speed CPU chip, multi-CPU control system and AC digital servo system, while taking measures to improve the dynamic and static characteristics of the machine tool, so that the speed of large CNC gantry milling efficiency and accuracy has been greatly improved. Overseas, the MTBF value of the current large CNC gantry milling equipment can reach more than 6000h, and the MTBF value of the servo system can reach more than 30000h, with very high reliability. With the future development of science and technology, the CPU chip will reach a higher speed, servo system will be more perfect, large CNC milling performance will be more enhanced.
2、Functional development trend
CNC system is an important accessory for large CNC gantry milling, the operator through the user interface to operate the CNC system, so as to control the large CNC gantry milling on the workpiece processing, due to different user requirements for the interface, and therefore the development of the user interface workload is great, the user interface has become one of the most difficult part of the development of computer software, the emergence of graphical user interface greatly facilitates the use of non-professional The use of users, people can operate through windows and menus, to facilitate blueprint programming and rapid programming, three-dimensional colourful three-dimensional dynamic graphics display, graphics simulation, dynamic tracking and simulation of graphics, different directions of the view and local display scale function. With the update of the CNC system, as well as the upgrade of the user interface body, the future of the large CNC gantry milling function will be greater development.
3、Structural development trend
The current large CNC gantry milling process using a highly integrated CPU / RISC chip and large-scale programmable integrated circuit we FPGA / EPLD / CPLD and special integrated circuit ASIC chip, can improve the integration of the CNC system and the hardware and software operating speed. The application of FPD flat panel display technology can improve the performance of the display, flat panel display with high technology content, light weight, small size, low power consumption, easy to carry and other advantages, can achieve a very large size display, and crt to compete with the emerging display technology, is the mainstream of the 21st century display technology, the application of advanced packaging and interconnection technology, the semiconductor and surface mount technology into one, by improving integrated circuit density, reduce the length and number of interconnections to reduce product prices, improve performance, reduce component size and improve system reliability. With the further development of intelligent technology, the size of chips and integrated circuits will be reduced to a smaller size, and the structure of large CNC gantry milling equipment will be further enhanced.
With the continuous exploration of human beings, the development of science and technology will be unlimited, and the future of large CNC gantry milling will also be greater development, the future of the intelligent world will make the large CNC gantry milling process more intelligent.
