CNC High Speed Precision Parts Processing Flow
Oct 29, 2018

CNC high-speed precision parts processing mainly refers to the use of digital information recorded on the media to control the machine tool, so that it automatically performs the specified processing tasks. CNC machining can ensure high processing precision and stable processing quality; easy to automate the operation process; high productivity and short production cycle; can greatly reduce the process equipment, adapt to the needs of rapid product replacement; it is usually closely connected with CAD Get up and realize the transformation of design ideas into the final product. Participants should focus on the relationship between the processes and the meaning of each step in the learning process of the entire CNC high-speed precision parts. Broadly speaking, the entire process consists of product analysis—graphic design—process planning—path generation—path simulation—path output—processing—inspection. In this part, a specific case is completed by means of demonstration, focusing on understanding the connection of each link. The materials processed in the case are two-color plates or plexiglass.

1. Product Analysis Through product analysis, certain composition information and some specific processing requirements should be obtained.


2, graphic design Graphic design should first be based on the detailed analysis of the product, such as the processing of the seal, we must determine the font, text size, stamp type, etc. by analyzing the processing requirements.


3. Process planning Through the analysis of the appearance and processing requirements of the workpiece products in the early stage, each processing step is reasonably established from the overall processing.


4. Path generation The process of path generation is actually that we implement the process planning through software, and at the same time optimize the tool path by setting the parameters.


5. Path Simulation After the path is generated, we generally have no intuitive feeling about its final performance on the machine. Here we can check the possible problems through the path simulation, thus reducing the actual processing scrap rate. The general inspection focuses on the effect of the appearance of the workpiece, whether it is overcut or undercut, and then whether the process planning of the path is reasonable.


6. Path Output Path output is a necessary step for software design programming to be implemented on the machine. The path output can be linked by the intermediate reference. If the student has a background in CNC, he can also understand it as post-processing of the tool path.
