Dongguan CNC machining process

Dongguan CNC machining mainly refers to the use of digital information recorded on the media to control the machine tool so that it can automatically perform the specified machining tasks. Numerical control processing can ensure that products reach extremely high processing accuracy and stable processing quality; the operation process is easy to realize automation; Dongguan CNC processing has high productivity and short production cycle; it can greatly reduce process equipment to meet the needs of rapid product replacement; it is usually CAD is closely connected to realize the transformation of design ideas to final products. The students should focus on the connection between the processes and the meaning of each step in the study of the entire CNC machining process. Broadly speaking, the composition of the entire process includes product analysis-graphic design-process planning-path generation-path simulation-path output-processing-inspection. In this section, a specific case is completed by way of demonstration, focusing on understanding the connection of each link. The material processed in the case is two-color plate or plexiglass.

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

2. Graphic design The graphic design should first be based on a detailed analysis of the product. For example, for the processing of the seal, we must determine the font, text size, and seal type by analyzing the processing requirements.

3. Process planning Through the analysis of the appearance and processing requirements of the workpiece product 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 to a certain extent through parameter settings.

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