  針對模具設計制造的特性及普通加工設備在模具設計制造方面的局限性,普遍運用數控機床加工模具就成為必然的選擇。模具數控加工技術的特性是:
  Aiming at the characteristics of die design and manufacturing and the limitations of common processing equipment in die design and manufacturing, it is inevitable to use NC machine tools to process die. The characteristics of NC machining technology for die and mould are as follows:
  1、模具的構造復雜且部件多,模具中的模架、型腔、型芯、鑲塊或滑塊、成型電術等部件需求經過數控加工成形,數控加工工作量大。
  1. The structure of the die is complex and there are many parts. The parts of the die frame, cavity, core, insert or slider, forming electronics and other parts need to be processed by NC, and the workload of NC processing is large.
  2、合理布置數控加工與普通加工,對某些既能夠運用普通機床加工,又能夠經過數控機床加工成形的零件,需綜合思索其加工時間、加工本錢以及普通機床的加工才能,停止統籌布置。
  2. Reasonable layout of NC processing and ordinary processing, for some parts which can be processed by both ordinary machine tools and NC machine tools, we need to consider the processing time, processing cost and processing ability of ordinary machine tools comprehensively, and stop overall layout.

  3、模具部件普通需求幾工序才干完成加工,應盡量布置在一次裝置下全部完成,這樣能夠防止因屢次裝置形成的定位誤差并減少裝置時間。
  3. Mould parts need several common processes to complete the processing, should be arranged as far as possible in a single device to complete, so as to prevent positioning errors caused by repeated devices and reduce device time.
  4、模具的請求精度高,數控加工時需求制定合理的加工工藝參數,選用合理的刀具、來嚴厲控制加工誤差。
  4. The precision of mould request is high. When NC machining is needed, reasonable processing parameters should be worked out, and reasonable cutting tools should be selected to strictly control machining errors.
  5、普通塑料制品的外形考究流水外型、潤滑美觀,使得模具的型腔面構造復雜,因而選用三軸或四軸聯運的加工中心來加工,并且盡可能加工一次到位,盡量減少后續鉗工修銼和手工拋光工作量。

  5. The appearance of ordinary plastic products is exquisite in flowing water and beautiful in lubrication, which makes the cavity surface of the die complex. Therefore, three-axis or four-axis intermodal processing center is selected to process, and the processing is in place as soon as possible, so as to minimize the workload of subsequent fitter repair files and manual polishing.
  6、在刀具切削加工時,要思索后道工序的加工便當,為后道工序提供較好的外表粗糙度,互相位置精度較高的基準平面。
  6. When cutting tools, it is necessary to consider the convenience of the latter process to provide better surface roughness for the latter process and a reference plane with higher mutual position accuracy.
  7、在數控加工時必需采用高硬度的硬質合金刀具,選擇合理的切削工藝參數停止加工,有條件的比較好用高速銑削來加工。
  7. High hardness cemented carbide cutters must be used in NC machining. Reasonable cutting parameters should be selected to stop the processing. High speed milling is the best method when conditions permit.
  8、盡量采用規范件,如將孔的直徑規范化、系列化可減少金屬切削量,降低加工本錢,進步加工效率。
  8. Making use of standard parts as far as possible, such as standardizing and serializing the diameter of holes, can reduce metal cutting amount, reduce processing cost and improve processing efficiency.

  9、推行運用CAD/CAM技術,對模具零件的數控加工程序停止自動編列與優化,為模具的數控加工樹立一套完好的數控工藝流程,按既定的辦法和步驟停止數控加工,避免或減少模具制造的錯誤。
  9. Implement the application of CAD/CAM technology to stop automatically arranging and optimizing the NC processing program of die parts, establish a complete set of NC process flow for the NC processing of dies, stop the NC processing according to the established methods and steps, and avoid or reduce the errors of die manufacturing.
  10、在模具加工中,關于尖角、筋條等部位,無法用機床加工到位,另外某些特殊請求的產品,需求停止電火花加工。而電火花加工要用到電極,模具電極經過采用紫銅和石墨,石墨具有易加工,電加工速度快,價錢廉價,重量輕的特性。但在數控加工時,石墨粉塵對機床和操作者的損傷極大,要用專用的吸塵安裝或者浸在液體中停止加工,需求用專用數控石墨加工中心。因而 ,數控加工時運用紫銅作為電極運用和首選 ,并且要示高的采用鎢銅合金作為電極。
  10. In the process of die and mould processing, it is impossible to use machine tools to process sharp corners, ribs and other parts. In addition, some products with special requests need to stop EDM. Electrodes are used in EDM. The die electrodes are made of copper and graphite. Graphite is easy to process, fast to process, cheap and light in weight. However, in NC machining, graphite dust has great damage to machine tools and operators. It is necessary to install special dust collectors or immerse them in liquid to stop processing. It is necessary to use special NC graphite processing center. Therefore, copper is the preferred electrode in NC machining, and tungsten-copper alloy should be used as the electrode.
