Introduced CNC machining process
CNC machining mainly refers to digital information recorded in the above media control over the machine, it automatically executes a predetermined processing tasks. CNC machining can ensure that products meet high precision and stable machining quality; easy to automate the operation; high productivity, short production cycle; can greatly reduce process equipment, need to adapt to rapid product replacement; it is usually closely co-ordinated with CAD up design ideas to achieve conversion of the final product. Trainees learn the entire CNC machining process should focus on the link between the process and each step of the meaning of existence. Broadly speaking, the composition of the entire process, including product analysis - Graphic Design - Process Planning - path generation - path simulation - path output - processing - test. In this link to a specific case by demonstrating manner, focusing on understanding all aspects of convergence, case processing material for color or plexiglass plate.
1, the product analyzed by product analysis should get some information about the composition and some specific processing requirements.
2, the first graphic design graphic design should be based on careful analysis of the product, such as for seal processing, we will determine the font, text size, type, etc. Along with the analysis processing requirements.
3, through the pre-planning process workpiece appearance and processing requirements analysis, from the global to establish a reasonable processing for each processing step.
4, generating path path generation process is actually put us through process planning software to achieve, at the same time by setting the parameters for a certain tool path optimization.
5, the path simulation path in the future generation, we generally have it end up in the machine above the performance results are not intuitive feeling. Here we can check for possible problems through path simulation, thereby reducing the rejection rate of the actual processing. Check the general appearance of the work focused on the effect, whether over-cutting or under-cut, then there is a path planning process is reasonable.
6, the output path output path is a necessary step in the programming software design tools to achieve the above, we can establish contact through the path of the output from the intermediate reference for both. If students have CNC professional background, it can also be understood as a post-processing tool path.
