The Origin of CNC Machine Tool Programs

Introduction to CNC Machine Tool Programs


The reason why CNC machine tools can process parts of different shapes, sizes, and accuracies is because programming personnel have developed different machining programs for them. So, CNC programming is the most important part of using CNC machine tools. It plays an important role in product quality control. Numerical control programming technology involves knowledge in various disciplines such as manufacturing processes, computer technology, mathematics, artificial intelligence, and differential geometry< Br/>


Before CNC programming, the technical requirements, geometric shapes, machining content, machining accuracy, etc. specified on the part drawings are analyzed first; On the basis of analysis, determine the machining plan, machining route, tool alignment point, tool and cutting amount, etc; Then perform necessary coordinate calculations. On the basis of completing process analysis and obtaining coordinates, the determined process, process parameters, tool displacement and direction, and other auxiliary actions are compiled into a program sheet according to the tool path and the instruction code and program format specified by the CNC system. After verification, it is input into the CNC system through various methods such as MDI, RS232C interface, USB interface, DNC interface, etc. to control automatic machining of the machine tool. The entire process from analyzing part drawings to obtaining the required CNC machining programs for CNC machine tools is called CNC programming< Br/>
