What is CNC Machine
Ordinary machine tools have a history of nearly 200 years. Traditional machining is composed of basic machining methods such as turning, punching, cutting, planing, grinding and drilling. Around different processes, people use lathes, punching machines, cutting machines, planing machines, grinding machines, drilling machines, etc.
With the development and comprehensive application of electronic technology, computer technology and automation, as well as precision machinery, location measurement and other technologies, the proportion of ordinary turning, milling, boring and drilling machines has decreased year by year, and a new type of mechatronic machine tool – numerical control machine tool has been developed, including numerical control lathe, numerical control punch machine vertical machining center, horizontal machining center, etc.
CNC Machine and CNC Technology
CNC machine tool class is a kind of mechatronic processing equipment that automatically processes the machine tool according to the given motion track through digital signal control After half a century of development, CNC machine tools have become one of the important symbols of modern manufacturing industry. The application of manufacturing CNC machine tools in China is becoming more and more extensive, which is the embodiment of the comprehensive strength of an enterprise. Numerical control technology is the method to control numerical control machine tools. There are both connections and differences between the two. See below.
Contents of CNC Machine and CNC Technology
It is a technology that controls and manipulates a certain instruction through numbers, which is called CNC for short. It refers to a method to realize automatic control of the working process of the control object by using the program composed of digital code.
In short, the numerical control technology class is the means of operation, and the numerical control machine tool is the object of operation.
The fifth Technical Committee of the International Federation for information processing (IFIP) defines a numerical control machine as follows: a numerical control machine tool is a machine tool equipped with a program control system, which can logically process programs with use numbers or other symbol coding instructions. This definition is referred to as the program control system printed CNC system.
We can simply understand that various operations and steps in the part processing process, as well as the relative displacement between the tool and the workpiece, are recorded on the media with digital codes, and sent to the counter or CNC system. After decoding, calculation and processing, the relative motion of the tool and the workpiece of the machine tool is controlled to process the required parts. Such machine tools are collectively referred to as CNC machine tools.
That is, the program we have compiled, including instructions composed of letters and numbers
It refers to the operation of changing spindle speed, spindle forward and reverse rotation, tool change, cutting fluid switch, etc Step refers to the machining sequence of the above operations.
Relative displacement between tool and workpiece
That is, the tool path We set the relative value between the tool and the workpiece by setting the tool.
That is, the location where the program is stored, such as disk, optical disc, paper tape, etc
Decoding operation and processing
It refers to translating our program into the NC system or other instructions that can be set by the computer Print computer language.
