CNC machining mainly refers to the use of digital information recorded on a medium to achieve machine control and automatically perform the required processing tasks. CNC machining can ensure that products achieve high machining accuracy and stable machining quality; Easy to automate operation process; High production efficiency and short production cycle; It can greatly reduce the need for rapid product replacement of process equipment; It is usually closely linked to CAD Up, achieving the transformation of design ideas to the final product.

Throughout the CNC process, emphasis should be placed on the connection between the process and the existence of each step. Generally speaking, the entire process consists of product analysis, graphic design, process planning, path generation, path simulation, path output, processing, and verification.

1. Product analysis obtains certain composition information and specific processing requirements through product analysis.

2. Graphic design should first be based on a detailed analysis of the product, determine the type of graphic through analysis and processing requirements, and draw through graphic software.

3. Process planning analyzes the appearance and processing requirements of pre workpiece products, from global processing to reasonable establishment of each processing step.

4. The process of generating paths is actually implemented through software, and is optimized to a certain extent by the parameters set by the tool path.

5. The simulation path usually has an impact on the final performance of the machine after production, which is not intuitive. Here, we can use path simulation to check for possible issues, thereby reducing the rejection rate of actual processing. The focus of general inspection is on the appearance of the workpiece effect, whether it is cutting or cutting, so the path of process planning is reasonable.

6. Path output Path output is a necessary step for software design and programming to implement the above steps in a machine. Through path output, two can be established through intermediate references. If you have a digital professional background, you can also understand it as tool path post-processing.
