In order for the precision part processing machine tool to act according to the requirements of part processing, these requirements must be notified to the part processing system in the form of instructions that can be recognized by the CNC system of the machine tool. The instructions that can be recognized by this system are called programs. It is a numerical control program.
The process of numerical control programming not only refers to the process of writing numerical control processing instructions, it also includes the whole process from part analysis to writing processing instructions to preparation of control media and program verification.
Before programming the program, you must first analyze the processing technology of the part to determine the processing route, process parameters, tool motion trajectory, displacement, cutting parameters (cutting speed, feed, and back tooling) and various auxiliary functions (Tool change, spindle forward and reverse rotation, cutting fluid switch, etc.): Then, write a processing program sheet according to the instructions and program format specified by the precision parts processing lathe; then record the content of this program sheet on the control medium (such as a floppy disk) , Mobile storage, hard disk), after checking that it is correct, use manual input or computer transmission to input into the numerical control device of the numerical control machine tool, so as to direct the machine tool to process precision parts.
