1= pieces processed on CNC machine tools are generally divided into processes according to the principle of process concentration. According to the processing characteristics of CNC machine tools, the CNC machining steps are divided in the following ways:
- Divide the process according to the clamping and positioning. For a piece with little addition content, the process can be divided according to the clamping and positioning, that is, all the technological processes completed by one clamping are divided into one process. Usually, the processing part is first divided into several parts, and each process processes one part. CNC machine tools, for example, when machining the outer contour, clamp the inner cavity; when machining the inner cavity, clamp the outer contour.
- Divide the process according to the tool used In order to reduce the number of tool changes and the idle travel time, the process can be divided according to the tool.In one clamping, all parts that can be machined are completed with one knife and T, and then another knife is used to machine other parts. At this time, the process completed by the same tool can be divided into one process. This method of CNC machine tools is suitable for situations where the structure of parts is more complex, there are many surfaces to be processed, the continuous working time of the machine tool is long, and the preparation and inspection of processing programs are difficult. This method is mostly used in automatic tool changing CNC machine tools.
- Divide the T sequence according to roughing and finishing. Because the roughing T has a large cutting allowance, it will generate a large cutting force, which will deform the workpiece with poor cutting degree. The process can be divided according to the principle of separation of roughing and finishing, that is, the process completed in roughing is divided into one process, and the process completed in finishing is divided into one process.
- Divide the T sequence according to the added T part. For parts with a lot of added content, the processing part can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc., and the processing of the same surface is completed. The process is divided into a 1_: sequence. CNC machine tools generally add T plane and positioning surface first, and then process holes; first process simple geometric shapes, and then process complex geometric shapes; first add parts with lower precision requirements, and then add parts with higher T precision requirements.
CNC (Computer Numerical Control) machine tool processes are divided into several main categories, each serving a specific purpose in the manufacturing process. These processes are controlled by computer programs that interpret design files and convert them into precise movements of the machine tool. The major divisions of CNC machine tool processes include:
Milling
Milling is a CNC process that uses rotary cutters to remove material from a workpiece to create complex shapes, profiles, and features. It can be done in various directions (e.g., along the X, Y, and Z axes) and is suitable for both flat and curved surfaces.
Turning
Turning is a CNC process performed on a lathe where the workpiece rotates while a cutting tool removes material from the outer diameter of the workpiece. This process is used to create cylindrical parts, such as shafts and rods.
Drilling
Drilling is a CNC process used to create holes in a workpiece. It involves rotating a cutting tool with two cutting edges to penetrate the material and create cylindrical holes of various diameters.
Boring
Boring is similar to drilling but is used to enlarge existing holes or achieve greater precision. A single-point cutting tool is used to remove material from the interior of an existing hole to achieve the desired size and finish.
Grinding
Grinding is a precision machining process that uses an abrasive wheel to remove material and achieve very tight tolerances and surface finishes on the workpiece. It is commonly used for finishing operations.
Routing
Routing involves cutting out specific shapes from a larger workpiece using a rotating cutting tool with multiple cutting edges. It is commonly used in woodworking, plastic fabrication, and metalworking.
Electrical Discharge Machining (EDM)
EDM is a process that uses electrical discharges (sparks) to remove material from the workpiece. It is commonly used for machining complex shapes and hardened materials that are challenging to machine with traditional methods.
Laser Cutting
Laser cutting utilizes a high-power laser beam to cut through materials and create intricate shapes with high precision. It is commonly used for cutting metals, plastics, and other materials.
Waterjet Cutting
Waterjet cutting involves using a high-pressure stream of water mixed with an abrasive material to cut through materials. It is suitable for cutting a wide range of materials, including metals, composites, and stone.
Ultrasonic Machining
Ultrasonic machining is a process that uses ultrasonic vibrations in combination with an abrasive slurry to remove material from the workpiece. It is often used for brittle materials and delicate workpieces.
Each of these CNC machine tool processes offers unique advantages and is chosen based on the specific requirements of the part being manufactured, including material, geometry, tolerances, and surface finish.
In summary, the division of the process should be flexibly grasped according to the structural characteristics of the parts, the installation method of the small pieces, the content of CNC plus T, the performance of the CNC machine tool, and the production conditions of the factory, and strive to be reasonable.
