Programming is the Chinese abbreviation for programming, letting the computer solve the problem on its behalf, and stipulating a certain calculation method for a certain calculation system, so that the calculation system runs according to this calculation method, until the corresponding result is obtained. In order for the CNC machining center to better understand our intentions, we need to tell the computer the problems, ideas, methods, and means that need to be solved in a form that the computer can understand, so that the computer can work step by step according to our instructions and complete a certain Specific tasks. This process of communication between people and computing systems is called programming. The CNC machining center can not only greatly improve the processing quality and efficiency, because it is equipped with a programmable control automation system and other multi-station turrets, which can realize the processing and production of complex parts and high-precision parts, thus showing high practicability and high automation , High-precision and other related features. Programming is an important prerequisite for CNC machining centers. In the working process of the CNC machining center, the running process of the CNC machine tool is a series of activities carried out in accordance with the program prepared by the programmer in advance. If there is a problem with programming, it will definitely affect the quality of the CNC machining center from the source. In the actual operation process, the CNC machining center requires the origin of compilation, and the origin of compilation is determined by combining the programmer with the actual situation of each part. In this process, if the compilation origin is unreasonably selected, it will inevitably lead to very large errors in the entire operation of the CNC machining center, which will also have a serious impact on the quality of CNC machining.
