CNC lathes and turning centers are high-precision, high-efficiency automated machine tools. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing technology performance, and can process linear cylinders, oblique cylinders, arcs and various threads, grooves, worms and other complex workpieces. It has linear interpolation and arcs. Interpolate various compensation functions, and play a good economic effect in the mass production of complex parts.
"CNC" is the abbreviation of Computerized Numerical Control in English. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. We put the part's machining process route, process parameters, tool motion trajectory, displacement, cutting parameters (spindle revolutions, feed, back tooling, etc.) and auxiliary functions (tool change, spindle forward, reverse, etc.) Cutting fluid on, off, etc.), according to the instruction code and program format specified by the CNC machine tool, write a processing program list, and then record the content of the program list on the control medium (such as punched paper tape, magnetic tape, magnetic disk, magnetic bubble memory) ), and then input it into the numerical control device of the numerical control machine tool to command the machine tool to process the parts.
This whole process from the analysis of the part drawing to the preparation of the control medium is called the compilation of the numerical control program. The difference between CNC machine tools and ordinary machine tools processing parts is that CNC machine tools automatically process parts according to the program, while ordinary machine tools must be operated by humans. We can achieve the purpose of processing different parts by changing the program that controls the motion of the machine tool. Therefore, CNC machine tools are particularly suitable for processing small batches of parts with complex shapes and high precision requirements.
Since the CNC machine tool must process the parts according to the program, after the programmer compiles the program, it is input into the CNC device to direct the work of the machine tool. The input of the program is through the control medium.
