High-precision parts machining center working principle: write processing program (referred to as program), and according to the processing process requirements into the processing program (referred to as program) CNC, CNC according to the processing program will be transmitted to the servo (or stepper) motor drive module, servo (or stepper) motor according to the mechanical drive organization to complete the machine tool feed movement; spindle start and stop, tool selection, cooling, wetting, etc. Logic control code CNC by the machine electrical control system to complete the button, switch, display lights, relays, contactors and other output device control. At present, the programmable logic controller is generally used for machine tool electrical control (ProgramableLogicControler referred to as PLC), PLC has the advantages of small size, ease of use, high stability. This shows that motion control and logic control is the key control tasks of CNC machine tools.
Programming is CNC CNC machining plant according to the size of the part, processing technology, process parameters, tool parameters and other information, according to CNC write special programming code for processing procedures. CNC machining is CNC control of the machine tool according to the processing program to complete the parts processing.
