精密雕刻技术在复杂曲面模具加工中的应用

研究了精密雕刻技术在复杂曲面模具加工中的优势,采用非标准小刀具使精雕机床能够实现在加工中心、数控铣上无法完成的小尺寸加工。提出将精密雕刻技术应用于复杂曲面模具的加工,完成复杂曲面细小特征的加工,从而提高模具加工的速度,加快新产品开发的进度,降低开发成本,实现模具的快速制造,改变了传统的仅依靠数控铣床、加工中心进行模具制造的模式。最后以某塑料件模具的加工为例,阐述了精密雕刻技术在模具加工中的应用方法。

Application of Precision Engraving Technique in the Processing of Mould with Complex Curved Surface

The advantages of the precision engraving technique in processing of mould with complex curved surface are studied.The small tools of precision engraving machine can be used to realize the small size processing which is unachievable for CNC and NC milling machine.The method using precision engraving machine to manufacture mould with complex curved surface with small features is proposed,so the speed of mould processing is accelerated,the cost of new product development is decreased,the rapid manufacturing is realized and the traditional design method using only CNC and milling machine is improved.Finally,this method has been applied to the processing of a plastic mould as an example and the application method is expounded.
