What are the processes for four-axis CNC machining?

The composition of the entire process includes product analysis-graphic design-process planning-path generation-path simulation-path output-processing-inspection. In this session, 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 of four-axis CNC machining
    Certain compositional information and some specific processing requirements should be obtained through product analysis.
  2. Graphic design for four-axis CNC machining
    Graphic design should first be based on a detailed analysis of the product. For example, for stamp processing, we must determine the font, text size, stamp type, etc. through analysis of processing requirements.
  3. Process planning for four-axis CNC machining
    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 realize 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 is generated, we generally do not have an intuitive feeling about its final performance on the machine tool. Here we can check the possible problems through path simulation, thereby reducing the scrap rate of actual processing. The general inspection focuses on the appearance of the workpiece, whether it is over-cut or under-cut, and then whether the process planning of the path is reasonable.
  6. Path output
    The path output of four-axis CNC machining is a necessary step for software design and programming to be realized on the machine tool. The path output can establish a connection between the two by referring to the middle. If the students have a professional background in CNC, it can also be understood as the post-processing of the tool path.
