This paper takes the machining of the core of the excavator toy mold as an example,analyzes the CNC machining process of the mold core,and completes the machining of the complex curved surface of the injection mold construction core cavity.By analyzing the drawbacks of the traditional rough machining method,it is improved to a new machining process.Compared with the layered milling rough machining in the traditional machining process,dynamic milling can shorten the processing time.By using the new processing technology,the feed length and feed time of rough machining have been reduced by 72.929%and 81.369%,respectively.The total cutting time of the entire rough machining has been reduced by 81.247%.This process method effectively improves processing efficiency and saves time and costs.Secondly,the service life of the cutting tools has been significantly increased,reducing the frequency of tool replacement and improving production efficiency.Ultimately,the stability of processing quality is achieved,ensuring the accuracy and quality requirements of the parts.
