Introduction to CNC Processing Factory: The Process of CNC Processing

CNC machining mainly refers to the use of digital information recorded on the media to control the machine tool, so that it automatically performs the specified processing tasks.

①Due to the limitation of the technology of The Times, the traditional optical system has relatively simple structure and component shape. The processing accuracy of traditional optical components depends on the process method, and low precision machining machines can still achieve high optical component processing accuracy. Such machines are often referred to as "Nondeterministic" processing machines. "Non-deterministic" processing machines using traditional processing methods are only suitable for processing simple shapes such as balls and planes and optical components of hard and brittle materials such as glass.

With the development of science and technology, especially the development of modern optoelectronic technology and computing technology, today's optical application system has undergone great development and changes in the complexity of optical components, the diversity of materials, and the small and large geometric scales. Traditional "non-deterministic" processing machines and methods have been unable to meet the needs of modern optical system components processing: either they cannot be processed at all, or the processing efficiency is extremely low. Modern ultra-precision machining machine tools came into being, which specifically refers to "Deterministic" ultra-precision machining machines.

②Key technology of ultra-precision machining machine tool

Overall integrated design technology of machine tool system. Conventional machine tool design and manufacturing, each link has a great tolerance in technology. Each link of ultra-precision machine tools is basically in a technical limit or critical application state, which link is slightly considered or mishandled, will lead to overall failure. Therefore, the design needs to have a very comprehensive and deep understanding of the overall machine tool system and various parts of the technology. According to the feasibility, it is necessary to carry out the associated comprehensive design from the whole.

High rigidity, high stability machine body structure design, manufacturing technology. In particular, LODTM machine tools, due to the large fuselage, its own weight, the weight of the bearing workpiece changes, any small deformation will affect the processing accuracy. Structural design not only from the material, structural form, process to meet the requirements, but also to take into account the operation of the machine tool operability.

Ultra-precision workpiece spindle technology. Medium and small machine tools often use aerostatic spindle scheme. The aerostatic spindle has low damping and is suitable for high-speed rotary machining applications, but the load carrying capacity is small. The rotary accuracy of the aerostatic spindle can reach 0.05μm.

LODTM machine tool spindle bearing the size of the workpiece, the weight is large, generally appropriate to use the hydrostatic spindle. The hydrostatic spindle has large damping, good vibration resistance and large bearing capacity, but the hydrostatic spindle is hot at high speed, so it needs to take liquid cooling and constant temperature measures. The rotating accuracy of the hydrostatic spindle can reach 0.1μm. In order to ensure the accuracy and stability of the spindle, both the pressure source and the hydraulic source need constant temperature, filtration and pressure precision control.

Ultra-precision rail technology. Early ultra-precision machine tools used aerostatic guide technology. Aerostatic guide rail is easy to maintain, but the damping is small and the bearing and vibration resistance is poor, so it is rarely used now. Closed hydrostatic guide rails have the advantages of high vibration damping, high stiffness and large bearing capacity. The main ultra-precision machining abroad is now mainly using hydrostatic guide. The ultra-precision hydrostatic guide has a straightness of up to 0.1μm.

 

③Nanoscale resolution dynamic ultra-precision coordinate measurement technology.

Laser interferometry is a high precision standard geometric measurement standard, but it is easily affected by environmental factors (air pressure, humidity, temperature, airflow disturbance, etc.). To this end, LLNL's LODTM coordinate laser measurement loop uses vacuum isolation and a zero temperature coefficient InvAR coordinate measurement frame measure. This is also the application of laser coordinate measurement.

Nowadays, most of the coordinate measuring systems of ultra-precision machine tools use diffraction grating. The grating measurement system has high stability and resolution up to nm level. In order to further obtain ultra-high position control characteristics and machined surface quality, DSP subdivision is used, and the resolution of the measurement system can be up to nanometers.

Nanoscale repeatable positioning precision ultra-precision transmission, drive control technology. In order to achieve deterministic ultra-precision machining at the optical level, the machine tool must have the quality of tool motion control with nanoscale repeated positioning accuracy. The servo transmission and drive system need to eliminate all nonlinear factors, especially the effects such as friction of the moving mechanism with nonlinear characteristics. Therefore, the use of air float, liquid float and other bearings without static friction effect, guide rail, balance mechanism has become an inevitable choice. In addition to the high resolution and high real-time requirements of the servo motion controller, the control algorithm mode also needs to be improved.

Open high performance CNC system technology. Starting from the machining accuracy and efficiency, the CNC system not only meets the requirements of ultra-precision machine tool control display resolution, accuracy, real-time, but also needs to expand many auxiliary functions such as in-machine measurement, tool setting, compensation and so on. General numerical control system is difficult to meet the requirements. Therefore, ultra-precision machine tools are basically using PC motion controllers to develop open CNC numerical control system mode.
