DNC与CNC的区别

CNC (numerical control machine tool) is the abbreviation of computer numerical control machine tool, it is a kind of automatic machine tool with program control system. The control system is capable of handling a program that has control codes or other symbolic instructions, and will decode it, so that the machine tool moves and processes the parts. DNC is called distributed numerical control, which is the link between the CAD/CAM and the computer assistant production management system. It is another form of machining automation.

数控技术的定义

Numerical control technology, Control (Numerical). It is a method of controlling the motion and machining process of machine tools by using the information of digital.. The machine tool that is controlled by numerical control technology, or machine tool that is equipped with a numerical control system is called numerical control (NC) machine tool. The numerical control system includes: numerical control device, programmable controller, spindle driver and feeding device etc. numerical control machine tool is the product of machine, electric, liquid, gas and light height integration.. In order to realize the control of machine tools, the relative motion between the tool and the workpiece and the process information is needed to describe some technological parameters that the machine tool must have.. For example: feed rate, spindle speed, spindle is inverted, for knife, coolant switch, etc.. These information according to a certain format form document processing (i.e. normal said the NC machining program stored in the information carrier (such as a disk, perforated paper tape, magnetic tape, etc.) and then by machine tool CNC system read (or directly through the numerical control system keyboard input, or pass through the channel input), by the decoding, which makes the machine movement and machining parts. In modern NC machine tool is typical mechatronic products, basic technology of a new generation of production technology, computer integrated manufacturing system. The development trend of modern CNC machine tools is high-speed, high accuracy, high reliability, multi-function, complex, intelligent and open structure. The main development trend is the development of the software and hardware of the open architecture of the intelligent full-featured general numerical control device. Numerical control technology is the basis of machining automation, and it is the core of NC machine tools.

什么是柔性制造

The first aspect is the systems' ability to adapt to changes in the external environment, the system can satisfy the requirements of new products to measure; the second aspect is the system to adapt to changes within the capability and can be used in the interference (such as machine failure case and the productivity of the system with and without interference of productivity expectations ratio to measure. The "flexibility" is relative to the "rigid", the traditional "rigid" automatic production line to achieve a single variety of mass production

什么是集成制造

Integrated manufacturing system is also called computer integrated manufacturing system, in which the global effect is more obvious.. In the product life cycle, the operation has its corresponding computer aided system, such as computer aided design (CAD) and computer aided manufacturing (CAM), computer aided process planning (CAPP), computer aided test (CAT), computer aided quality control system (CAQ)
