Briefly describe the process steps and advantages of CNC machining of prototype models

　　 There are several common processes for making prototype models: CNC prototype processing, 3D printing prototypes, silicone composite prototypes, sheet metal prototypes, low pressure perfusion prototypes, and so on. Today we will briefly describe the steps and advantages of CNC machining prototypes.

　　The prototype model is also called the first model. In layman's terms, after the design of an industrial product is completed, it is not put into production immediately. Instead, a small number of models should be made according to the drawings. The purpose is to see the samples of the finished product early. If you are not satisfied, you can modify the drawings. , Until finally there is no objection, and then start mass production. This small number of models is the hand model in the mouth.

　　The steps of CNC prototype processing technology are as follows:

　　1) Negotiate the CNC processing price and delivery date, and sign a processing contract.

　　2) Analyze the part drawing and product assembly drawing, and perform process analysis on the part.

　　3) Select the blank.

　　4) CNC prototype programming.

　　5) Determine the machining allowance of each process, calculate the process size and tolerance.

　　6) Determine the equipment and tools, fixtures, measuring tools and auxiliary tools used in each process.

　　7) Determine the cutting amount and working hour quota.

　　 8) Determine the technical requirements and inspection methods of each main process.

　　9) Fill in the CNC prototype proofing process file.

　　 CNC prototype processing has the following advantages:

　　①No complicated tooling is required. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

　　②Sijunda prototype has stable processing quality, high processing precision, high repeatability, and meets the processing requirements of high-precision products.

　　③In the case of mass production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection.

　　④ It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.
