The key to the operation of CNC machining centers lies in the machining program. When machining different parts, it is only necessary to compile or modify the machining program from scratch to quickly meet the machining requirements, and there is no need to adjust the operation of the machine tool, which greatly shortens the technical preparation for replacing the machine tool hardware. time, so CNC is suitable for multi-variety, single or small batch production of parts. For parts with complex shapes, it is almost impossible for ordinary machine tools to complete, while CNC machine tools only need to compile corresponding programs, and can also complete the processing of some precision complex parts.
① Tool centralized sorting method This method is to divide the process according to the tools used, and use the same tool to complete all the parts that can be completed on the part. Then use the second knife and the third knife to finish what they can. This can reduce the number of tool changes, compress the idle travel time, and reduce unnecessary positioning errors.
② Roughing and finishing step-by-step method Roughing, semi-finishing, and finishing for a single part should be done first. For a batch of parts, roughing, semi-finishing, and finishing are all done first. Between roughing and finishing, it is best to wait for a period of time, so that the deformation of the parts after roughing can be fully recovered, and then finishing to improve the machining accuracy of the parts.
③ CNC parts are processed according to the order of processing parts. Generally, the plane and positioning surface are processed first, and then the holes are processed; the simple geometric shapes are processed first, and then the complex geometric shapes are processed; the parts with lower precision are processed first, and then the processing precision requirements are higher. part.
The moving parts of the CNC machining center move quickly in the empty stroke, and the replacement of the workpiece hardly needs to adjust the machine tool from scratch, and the machining accuracy is relatively stable. Generally, only the first-piece inspection and the sampling inspection of the key dimensions between the processes are performed, which greatly reduces the installation and shutdown inspections, etc. The auxiliary production time improves the processing yield and reduces the processing cost, and the larger the production batch, the lower the processing cost.
CNC parts processing is based on production needs. After opening, some small parts, such as small parts, can be punched and then processed by gong cutting or CNC processing. This is a lot in the production of eyeglass accessories and auto parts. When making a container, it is almost a matter of welding after cutting and punching, then sanding and spraying oil, and then assembling the accessories before shipment. For small parts, a lot of polished surfaces are required, electroplating or oil injection, and then welding or screwing to assemble and package for shipment.
CNC machining uses a subtractive process, which means that the raw material is processed into its final form by subtracting and removing material. Drilling holes, lots and paths are drilled and metal stock is shaped into new materials with different tapers, diameters and shapes. For subtractive manufacturing, shape is achieved by subtracting material. This is in stark contrast to other types, such as additive manufacturing, where materials are added, layered, and deformed into specified shapes. It also contrasts with injection molding, in which a mold is used to inject materials in different states of matter and into specific shapes.
CNC machining is widely used in all walks of life. Common in aerospace, automotive, consumer electronics, robotics, agriculture, and other fields where metal parts are frequently used. It is also widely used in medical devices, household goods, energy, oil and gas, and other consumer applications. It is one of the most common manufacturing processes in the world.
The characteristics of cnc processing are as follows: 1. Reduce the number of tooling, and do not need complex tooling to process parts with complex shapes; 2. Stable processing quality, high processing accuracy, high repeatability, and adapt to the processing requirements of aircraft; 3. Types, In the case of small batch production, the production efficiency is high; 4. It can process complex surfaces that are difficult to process by conventional methods, and even process some unobservable processing parts. In summary, it is the kind of complex structure with many products in small batches. It is more suitable for precision parts, such as precision shafts, fiber tail handles, pins, etc.
