CNC machining mainly refers to the use of digital information recorded on the media to implement control of the machine, so that it automatically performs the required processing tasks. CNC machining can ensure that the product to achieve high processing accuracy and stable processing quality; easy to automate the operation process; high productivity, short production cycle; can greatly reduce the process equipment to meet the needs of rapid product replacement; it is usually closely linked with the CAD Up, to achieve the design ideas to the final product transformation.

In the entire CNC process should focus on the link between the process and the existence of each step in the sense. Broadly speaking, the composition of the entire process includes product analysis - graphic design - process planning - path generation - path simulation - path output - processing - inspection.

1, product analysis through product analysis should obtain a certain composition information and some specific processing requirements.

2, graphic design graphics design should first be on the basis of detailed analysis of the product, through the analysis of processing requirements to determine the type of graphics, and through the graphics software to draw.

3, process planning through the pre-workpiece products for the appearance and processing requirements of the analysis, from the global processing to rationally establish each processing steps.

4, the path to generate the process of generating the path is actually we plan to achieve through the software, while the parameters set by the tool path for a certain optimization.

5, the path simulation path in the production after we generally will it on the final performance of the machine above the effect is not intuitive feeling. Here we can check the possible problems through the path simulation, thus reducing the actual processing of the rejection rate. The general examination of the focus on the appearance of the effect of the workpiece, whether cut or cut, and then there is the path of the process planning is reasonable.

6, the path output path output is the software design and programming in the machine to achieve the necessary steps above, through the path output can be established by the middle reference for the two. If you have a digital professional background, you can also understand it as a tool path post-processing.
