CNC (CNC machine) is a short for Computer number control, is a program control system with automatic machine tools. The control system can logically process a program with control codes or other symbolic instructions and decode it so that the machine moves and processes the part. Numerical Control referred to as NC technology refers to the use of digital, text and symbols of digital instructions to achieve one or more mechanical equipment, motion control technology. CNC is generally a general or special computer to achieve digital program control, so CNC is also known as computer numerical
1. High precision, with a stable processing quality;
2. Can be multi-coordinate linkage, can process the complex shape of the parts;
3. Processing parts change, generally only need to change the NC program, can save production preparation time;
4. The machine itself is high precision, rigidity, can choose a favorable amount of processing, high productivity (generally 3 to 5 times the normal machine);
5. Machine automation is high, can reduce the labor intensity;
6. The quality of the operator requirements are higher, the technical requirements for maintenance personnel higher.
CNC machining generally need to follow the following principles:
1. The accuracy and surface roughness of the workpiece to be machined should be ensured.
2. To minimize the processing route, reduce the empty travel time, improve processing efficiency.
3. Simplify the computational effort and simplify the machining process.
4. For some reusable programs, use subroutines.
CNC in the mold processing application and importance:
In recent years, due to rising labor costs, the mold template preparation work has been gradually replaced by CNC, compared to the previous manual preparation of its advantages: the relative position of the processing hole accuracy, high hole accuracy, and the work efficiency has been great Ascension. In addition, the metal mold surface, shaped forming parts; plastic mold forming cavity processing are required to use CNC machining process.
CNC processing, it is two parts, one is part of the machine, one is part of the programming, the two points and together, combined, is the need for division of labor, stressed that with the spirit. Why do you think it’s time? Because the machine is mainly working on the need to work on the mold workpiece on the machine table, the pressure plate, playing table, sub-center, the knife, the control panel coordinate exchange, and computer transfer program, start processing automatically, is an implementation jobs. And the programming part of the work is mainly need to be processed mold workpiece structure design, set the mechanical system, editing processing, processing area, processing procedures, design procedures … the two can be separate, independent work, but both But also must be connected to each other, for the processing of the workpiece processing parts, the number of points, the knife point, datum direction, the pressure plate position, as well as the processing of the spindle speed adjustment, cutting speed adjustment, blade loss of the replacement, People need to explain clearly, for the mold out of the finished product is fresh, beautiful, with jargon, life is good or bad, the two are indispensable.
A good engineer of the machine, is a good mold product direct quality inspectors, a good programming engineer is a good mold product image designer, the spirit of the two is a complete ISO quality system. Management of CNC milling processing system is to seize the key to the mold processing is the mold product duration and quality assurance, but also we pursue the efficiency and efficiency of the guarantee.
