CNC Machining mainly refers to the digital information recorded in the media to control the implementation of machine tools, so that it automatically performs the prescribed processing tasks. CNC Machining can ensure that products to achieve high processing precision and stable processing quality; The operation process is easy to realize automation, high production rate, short production cycle, and can reduce the process equipment, adapt to the needs of rapid upgrading of products; it is usually closely connected with CAD to realize the transformation of design thought to final product. The learners should focus on the link between the process and the meaning of each step in the study of the whole CNC machining process. Broadly speaking, the composition of the whole process includes product analysis--graphical design--Process planning--path generation--Path simulation--Path output--processing--inspection. In this link with a specific case through the demonstration of the way to complete, focusing on understanding each link of cohesion, case processing materials for two-color plates or plexiglass.
1, product analysis through product analysis should obtain a certain composition information and some specific processing requirements.
2, graphic design of the first product should be detailed analysis on the basis of, such as the processing of seals, we will analyze the processing requirements to determine the font, text size, seal type, etc.
3, the process planning through the early stage of the workpiece product appearance and processing requirements analysis, from the processing of the global to reasonably establish each processing step.
4, the path generation process is actually we have the process planning through software implementation, at the same time through the parameters of the set of tool paths for certain optimization.
5, path simulation path after the generation we will generally end up in the performance of the machine tool above it has no intuitive feeling. Here we can check the possible problems through the path simulation, thus reducing the actual processing of scrap rate. The general inspection focuses on the appearance of the workpiece effect, whether or not cut or less, then there is the path of the process planning is reasonable.
6, the path output path is the necessary step of software design programming in the machine tool implementation, through the path output can be the intermediate reference to establish a link between the two. If a student has a CNC professional background, it can also be interpreted as the post-processing of the Toolpath.
