CAD/CAM对模具高速加工的影响

Effect of CAD/CAM on the High Speed Machining of Mould & Die

介绍了CAD/CAM技术、高速加工的概念、模具高速加工及优势,重点分析了CAD/CAM对模具高速加工的影响。指出供模具高速加工使用的CAD模型必须能精确地表达出要加工的模型形状,模型精度必须大于加工公差,在可能的情况下,应将不需要进行高速加工的模型特征从模型中去除;正确选择高速加工刀具路径、提高CAM操作者和机床操作人员的编程能力、仔细安排加工顺序对获得良好高速加工结果至关重要。

The technology of CAD/CAM, High Speed Machining and the advantages of HSM of mould ＆die were introduced. The effect of CAD/CAM on the High Speed Machining of mould ＆ die was highlighted. Indicated that the CAD model used for HSM of mould ＆ die must exactly describe the model shape and the model accuracy must be more accurate than machining tolerance. As possible, the model characteristic not be machined by HSM could be rid from the model. To obtain good result of HSM, these are important that optimizing tool path of HSM, exalting ability of CAM user and machinery user and arranging machining order carefully.
