CAD/CAM applications in high speed machining (4)
(3) Use a continuous method, such as the offset path is usually better than the balanced path.
(4) Avoid vertical cutting, which should be cut from the outside of the material.
(5) In the critical area of ​​the part, ensure that the finishing path of the different steps will not be repeated, otherwise the tool marks will appear.
(6) Try not to change the knife and use a single tool to finish the critical area. Tool setting errors often result in tool marks on the machined surface after finishing.
(7) Long tools are prone to wear and should be used as short as possible. If possible, consider repositioning the part and using a short tool for machining in areas that are difficult to machine.
Third, the conclusion
(1) High-speed machining requires strict requirements for each part of the workpiece. The basic requirement is to use appropriate physical equipment and accurately specify the relevant parameters. Although it is difficult to specify which CAD and CAM functions are required for high-speed machining, it is certain that CAD and CAM have a significant impact on the quality and stability of high-speed machining.
(2) The CAD model used for high-speed machining must accurately express the shape of the model to be machined, which means that the accuracy of the model must be higher than the machining accuracy, and if possible, the model features that do not need to be milled are deleted or covered.
(3) High-speed machining equipment must be equipped with sufficient CAM programmers to ensure that the machine uses the best procedures. One of the ways to improve the quality of programming is to allow machine tool builders to program the machining process on the shop floor while ensuring that CAM operators and machine tool operators have received good technical training.
(4) If you want to obtain good high-speed machining results, the most effective method is to carefully arrange the processing sequence and use the processing conditions provided by the CAM system.
