The concept of numerical control machining is numerical control machining. It refers to a processing method for machining parts on a numerical control machine tool. The process specifications of the numerical control machine tool processing and traditional machine tool processing are generally the same, but obvious changes have also taken place. A digital machining method for controlling the displacement of parts and tools. It is an effective way to solve the variety of parts, small batches, complex shapes, high precision and high efficiency and automated processing.
CNC machining has the following advantages:
1, a large number of reduction in the number of tooling, machining complex parts do not require complex tooling. If you want to change the shape and size of parts, you only need to modify the parts processing program, which is suitable for the development and modification of new products.
2. The processing quality is stable, the processing precision is high, and the repeat accuracy is high. It can meet the processing requirements of the aircraft.
3. The production efficiency is high under the conditions of multiple varieties and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimal cutting amount.
4. It can process complex surfaces that are difficult to process with conventional methods and can even process some unobserved processing sites.
The disadvantage of CNC machining is that machine tool equipment is expensive and requires maintenance personnel to have a high level.
