The application of CNC equipment has made China's machining automation and intelligence, the processing efficiency has been significantly improved, and the finished products obtained are more fine. However, in the process of mold CNC machining, there are still some influencing factors, which affect the accuracy of the cost and the effect of processing, which are mainly reflected in the following aspects:

1. The product's own factors

The product itself factors are an important influencing factor of mold CNC machining, this influence is very common at present, the factors of the product itself are mainly reflected in two aspects, namely accuracy and quality. In the actual machining process, some molds themselves have very complex characteristics, this kind of mold in the production of often the accuracy requirements are very high, processing difficulty, mold this complex characteristics, it is easy to produce processing is not in place, in some details of the error, affect the effect of mold CNC machining, this kind of error mold often can not meet the requirements of use, must be processed in the details. In the process of mold CNC machining, the complexity of the mold structure is proportional to the difficulty of processing, the complex structure of the mold has very high requirements for various parameters, the requirements for CNC equipment and operators are very high, any operation error, will affect the overall effect of mold CNC machining, resulting in the embarrassing situation that the mold cannot be used.

2. Processing error

Contemporary machinery and equipment are very sophisticated, the requirements for component accuracy are very high, if there is a processing error, the equipment often cannot operate normally. In the process of mold CNC machining, the greatest impact on the accuracy is the parameters, the accuracy of the parameters must be guaranteed, so as to ensure that the finished products after processing can meet the actual application standards, but in the actual production process, the setting of parameters is a very difficult work, it is easy to make mistakes, thereby affecting the processing of the mold and producing unqualified products. The reasons for this situation are mainly divided into two types, first, in the process of mold CNC machining, due to the low quality of the staff, there are operational errors in the work, and unreasonable processing methods and processes are adopted, which will directly affect the effect of processing, and it is also a common problem that often occurs in mold CNC machining; Second, the effect of mold CNC machining will be affected by the equipment and the CNC system itself, if there is a problem in the CNC system and the processing equipment, it will cause insufficient processing accuracy, this situation can only be controlled as much as possible, reduce the impact of the system on the mold CNC machining, can not completely eliminate this impact. At present, how to reduce the processing error and improve the effect of mold CNC machining has become an urgent problem to be solved in mold CNC machining, and it is also the key breakthrough content of the industry.

3. Processing normative factors

Mold CNC machining has high requirements for accuracy, and this work itself has a certain technicality, in the processing, there is a set of strict specifications and processing processes, which is also a powerful means to improve the effect of mold CNC machining. If the staff does not strictly follow these specifications to carry out work, in the actual mold CNC machining process to change some procedures privately, or the specifications are not thoroughly studied, can not effectively implement the corresponding specifications, will directly affect the effect of mold CNC machining, mold accuracy will decline, serious will also cause the mold can not be used, this irregular operation caused by the processing problems, mainly reflected in the various detailed parameters of the mold, the performance of the mold has a great impact. In addition, in the process of mold CNC machining involves many application technologies, if the staff in the processing of these technologies selection errors, or the technology is not effectively implemented, will also bring different degrees of quality problems to the mold, reduce the accuracy of the mold.
