8. New process
In addition to metal cutting and forging, new machining processes and processes are emerging, and the concept of machine tools is changing. The field of laser processing is expanding. In addition to laser cutting and laser welding, laser hole machining, laser three-dimensional machining, laser heat treatment, and laser direct metal manufacturing are increasingly used. Electrical processing, ultrasonic machining, laminating milling, rapid prototyping technology, and 3D printing technology all show their magic.
9. New structures and new materials
The high speed and precision of the machine tool requires the simplification and light weight of the machine tool to reduce the negative impact of the machining inertia of the machine components on the machining accuracy and greatly improve the dynamic performance of the machine tool. For example, topology optimization of machine tool components by means of finite element analysis, design of "box-in-box" structure, and the use of hollow welded structures or lead alloy materials have begun to move from the laboratory to practical.
10. New design methods and means
China's machine tool design and development tools should be transferred from 2D CAD to 3D CAD as soon as possible. 3D modeling and simulation is the foundation of modern design and the source of technological superiority. Based on this three-dimensional design, CAD/CAM/CAE/PDM integration is carried out to speed up the development of new products, ensure the smooth operation of new products, and gradually realize product lifecycle management.
11. Direct drive technology
In conventional machine tools, the motor and machine tool components are connected by means of coupling elements such as belts, gears and couplings to achieve the required movement or rotation of the components. "Machine" and "Electric" are separated. The direct drive technology integrates the motor and mechanical components into a mechatronic functional component, such as a linear motor, an electric spindle, an electric ball screw and a torque motor. Direct drive technology simplifies the machine structure and increases machine stiffness and dynamics, speed and machining accuracy.
12. Open CNC system
The opening of the CNC system is the general trend. At present, the open CNC system has three forms: 1) Fully open system, which is a microcomputer-based CNC system, using a microcomputer as a platform, using a real-time operating system to develop various functions of the CNC system, transmitting data through a servo card, and controlling the coordinate axis motor. exercise. 2) Embedded system, namely CNC+PC, CNC controls the movement of the coordinate axis motor, PC as human-machine interface and network communication. 3) Converged system, adding PC motherboard based on CNC, providing keyboard operation and improving human-machine interface functions, such as Siemens 840Di and Fanuc 210i.
13. Reconfigurable manufacturing system
As the speed of product upgrades accelerates, the reconfigurability of specialized machine tools and the reconfigurability of manufacturing systems are increasingly important. Through the modularization of CNC machining units and functional components, the manufacturing system can be quickly reorganized and configured to suit the production needs of the variant. The standardization and standardization of interfaces for mechanical, electrical and electronic, liquid and gas, and control software is key to achieving recombinability.
14. Virtual machine tools and virtual manufacturing
In order to speed up the development speed and quality of the new machine tool, the virtual reality technology can be used in the design stage to evaluate the correctness and performance of the machine design before the machine tool has been manufactured. In the early stage, various errors in the design process are found and reduced. Loss, improve the quality of new machine tool development.
