CNC machining process is a kind of machining, but also abide by the rules of machining, and general machining process of the same general. Because it is a computerized control technology used in mechanical processing of an automated processing, which has high processing efficiency, high precision, processing technology has its own unique characteristics, the process is more complex, more detailed step arrangement.
CNC machining process, including the choice of tools, cutting parameters and to determine the routing process design and so on. CNC machining process is the foundation and core of CNC programming. Only when the process is reasonable, can we compile the CNC program with high efficiency and high quality. The criteria for measuring CNC programs are: Minimal machining time, minimum tool wear, and the best-machined work piece.
CNC machining process is the work piece as a whole part of the processing technology, or even a process. It and other processes before and after each other in order to eventually meet the overall machine or mold assembly requirements, so as to process qualified parts.
CNC machining processes are generally divided into roughing, coarse rough machining, semi-finishing and finishing and other steps. Roughing to try to use a larger knife, the power of the machine tool or within the scope of the tool as possible with a large amount of cutting quickly cut a large number of work piece material. In order to prevent rough cutting vibration when the work piece loosening, rough in the rough should be checked after school, if necessary, re-knife. You can rough the rough surface after the knife, ready for future school check. For work pieces with complex cavities, large openings are required for roughing out larger tools, necessitating a second roughing or cornering with smaller tools than roughing. Processing area is relatively large case, in order to reduce tool wear can be semi-finishing. The above steps in order to prevent over-cutting must leave enough margin, the final finishing process. Under normal circumstances, as far as possible in the machine test, qualified after removal, and then prepare the next piece of processing.
