cnc machine tools have been widely used in industrial consumption




with the rapid development of scientific technology and social consumption, mechanical products are becoming increasingly complex, and the demand for the quantity and consumption rate of mechanical products is increasing. in industries such as aerospace, military, and computer, parts have high precision, complex shapes, few batches, frequent corrections, difficult processing, low consumption efficiency, high rest intensity, and difficult quality assurance< br/>


the proactive process of mechanical processing technology is the most important means to adapt to the above development characteristics with intelligence. to address the aforementioned issues, a flexible, versatile, high-precision, and efficient&quo; flexibility; the proactive consumer equipment, cnc machine tools, has emerged in this situation. at present, cnc technology has gradually spread, and cnc machine tools have been widely used in industrial consumption, becoming an important direction for the proactive development of machine tools< br/>

1) the significance of cnc:



numerical control, also known as numerical control, is the abbreviation for numerical order control< br/>


the essence of numerical control is to actively master the mechanical installation and take measures through the digital information (not the changed digital quantity) under the specific processing method. it has the same nature as the sequence control (i.e. sequence control) through the continuous changed analog quantity. due to the mastery of information in cnc, and the processing of these short messages cannot be separated from a computer, the technique of actively mastering through a computer is referred to as cnc. the numerical control referred to here specifically refers to the numerical control (i.e. machine tool numerical control) used in machine tool processing. in addition, cnc is widely used in areas such as measurement, physical and chemical experiments and analysis, transmission of materials and information, construction, and scientific governance< br/>


2) classification of cnc:



the installation of nc in advanced cnc machine tools consists of various logic components and memory components, forming a random logic circuit. it is a fixed wiring hardware structure that realizes the cnc function through hardware, called hardware cnc. cnc machine tools implemented using this technique are also called nc machine tools< br/>


computer numerical control, abbreviated as cnc. the modern cnc system is a cnc system that adopts microprocessors or specialized microcomputers. the system sequence (software) stored in memory beforehand is used to master logic, achieve local or partial cnc functions, and connect with peripheral devices through interfaces. this type of machine tool is called a cnc machine tool< br/>




2. machine tool cnc and cnc machine tool



1) machine tool cnc



machine tool cnc refers to the process of programming tasks through machining sequence, and mastering themmoreover, the reverse clearance of the machine tool feed transmission chain and the uniform error of the screw pitch can be compensated for by cnc installation, resulting in higher positioning accuracy of cnc machine tools< br/>


3) stable and reliable processing quality



processing the same batch of parts, using the same cutting tools and processing sequence in the same machine tool under the same processing conditions, the path of the cutting tools is complete and identical, the consistency of the parts is good, and the quality is stable< br/>


4) high consumption rate



cnc machine tools can effectively increase the processing time and auxiliary time of parts. the spindle speed and feed rate of cnc machine tools are large, allowing them to perform strong cutting with large cutting amounts. cnc machine tools are currently entering the era of high-speed machining, and the rapid movement and positioning of moving parts of cnc machine tools, as well as high-speed cutting, have greatly improved the consumption rate. in addition, when combined with the tool library of the machining center, it can achieve continuous processing of multiple processes on a single machine tool, increase the turnover time between processes of semi-finished products, and improve the consumption rate< br/>


5) improve rest conditions



before the cnc machine tool is processed, it is adjusted and the output sequence is started, so that the machine tool can actively continue processing until the processing is completed. the operator only needs to perform tasks such as sequential output, editing, part loading and unloading, tool preparation, observation of machining conditions, and part testing. the intensity of rest decreases significantly, and the rest of machine tool operators tends to be intelligent tasks. in addition, individual machine tools are combined, which is both clean and safe< br/>


6) modernization of consumer governance


the processing of cnc machine tools can accurately predict the processing time afterwards, and the tools and fixtures used can be standardized and modernized, making it easy to achieve standardization of processing information. currently, it has been organically combined with computer assisted design and production (cad/cam), which is the foundation of modern integrated production techniques< br/>




4. development of cnc skills


1) high speed



the cnc system adopts a 32-bit or higher microprocessor, which enables the output, decoding, summation, output and other links of the cnc system to be achieved at high speed, and can improve the accuracy of the cnc system and achieve high-speed and high-precision machining of small sequence segments< br/>


the new cnc system currently under development adopts a 64 bit central processing unit (cpu), which strengthens the interpolation operation function and rapid feed function, realizes high-speed machining, and achieves multi axis control function. some control axes are 3; 15 axes, up to 24 axes at most, and can master up to 3 axes at the same time; 6-axis< br/>


2) multi functional



the cnc system has multiple monitoring capabilities
