The Sequence Of CNC Machining Is Very Important
There are often several surfaces on a CNC work piece that need to be machined. These surfaces not only have a certain degree of precision, but also have a certain positional requirement between the surfaces. In order to meet these precision requirements, the processing order of the surface of CNC work pieces cannot be arranged at random, but they must follow certain principles. This is the selection and conversion of the positioning reference determines the processing sequence.
China CNC Machining Service
1. Before the important surface processing, the fine reference should be closed once to ensure the processing accuracy of the important surface. CNC Machining is a process for machining parts on CNC machine tools. The process specifications of CNC machine tools and traditional machine tools are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batch size, complex shape and high precision, and to achieve high efficiency and automatic processing.
2. After the fine reference is processed, the main surfaces with high precision should be roughed, semi-finished and finished. Accuracy requires a particularly high surface that also requires finishing.
3. The surface as a fine reference should be processed at the beginning of the CNC Machining Process because it is used for positioning other surfaces in subsequent processes. CNC machining is commanded by the control system to make the tool meet the requirements of various movements, in the form of numbers and letters to indicate the shape and size of the work piece and other technical requirements and processing requirements. It refers to the process of machining parts on CNC machines. In order to improve the automation of production, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry.
4. When machining the precision datum, you need to use the coarse datum positioning. CNC machining is a process for machining parts on CNC machine tools. The process specifications of CNC machine tools and traditional machine tools are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batch size, complex shape and high precision, and to achieve high efficiency and automatic processing. In single-piece, small-scale production, or even mass production, for castings and forgings with complex shapes or large sizes, as well as blanks with large dimensional errors, the scribing should be arranged first before the machining process. Processes to provide a calibrated benchmark for precision bench-marking.
5. For the process that is prone to waste, finishing can be placed in the front, and some minor small surface processing can be placed behind it.
