In the field of machining, machining cutting tools are tools that directly contact the workpiece, and their performance and quality have a vital impact on the quality of parts manufacturing. The selection, use and maintenance of machining cutting tools are directly related to the processing efficiency, processing accuracy and surface quality of parts.1. Material selection of machining cutting toolsThe material of machining cutting tools determines its key properties such as hardness, wear resistance and toughness. Different processing materials and processing conditions require the selection of machining cutting tools of different materials. For example, high-speed steel tools are suitable for general turning, milling, drilling and other processing. They have the advantages of low price and good toughness, but relatively poor wear resistance; carbide tools have high hardness and good wear resistance, and are suitable for high-speed cutting and processing of materials with higher hardness; ceramic tools have higher hardness and wear resistance, and are suitable for ultra-high-speed cutting and processing of difficult-to-process materials. Therefore, when selecting machining cutting tools, the tool material should be reasonably selected according to the processing materials and processing requirements to ensure processing quality and efficiency.2. Geometric parameter design of machining cutting toolsThe geometric parameters of machining cutting tools, such as rake angle, back angle, main deflection angle, etc., have an important influence on cutting force, cutting temperature, chip morphology and machining surface quality. Reasonable design of the geometric parameters of the tool can reduce cutting force, reduce cutting temperature, improve chip morphology, thereby improving machining surface quality and tool life. For example, increasing the rake angle can reduce cutting force and make chips easier to discharge; increasing the back angle can improve the wear resistance of the tool and reduce cutting temperature; reasonable main deflection angle selection can improve the strength and rigidity of the tool while ensuring cutting force.3. Use and management of machining cutting toolsThe use and management of machining cutting tools is also a key link in improving the quality of parts manufacturing. First, the tool should be pre-adjusted to reduce the installation and adjustment time of the tool on the machine tool and improve processing efficiency. Secondly, when the tool is blunt, it should be sharpened or replaced in time to ensure the sharpness and processing accuracy of the tool. In addition, computer management of tools should be implemented, including storage management, borrowing and returning management, tool matching management, tool size measurement management, tool life management, etc., to ensure the rational use and effective management of tools.4. Maintenance of machining cutting toolsMaintenance of machining cutting tools is of great significance to extend tool life and maintain processing quality. During the processing, the chips and dirt on the surface of the tool should be cleaned regularly to avoid damage to the tool. At the same time, attention should also be paid to the storage environment of the tool to prevent the tool from being damp, rusted or corroded by other chemicals. For tools that are not used for a long time, anti-rust treatment should be carried out and properly kept.5. Combined with advanced manufacturing technologyWith the continuous development of advanced manufacturing technology, such as CNC machining, high-speed cutting, composite machining, etc., the requirements for machining cutting tools are getting higher and higher. Therefore, in the process of improving the manufacturing quality of parts, advanced manufacturing technology should also be combined to select machining cutting tools that are suitable for it. For example, in CNC machining, high-precision and high-rigidity CNC tools should be selected; in high-speed cutting, high-speed machining cutting tools with good thermal stability and wear resistance should be selected; in compound machining, compound tools that can achieve multiple machining functions should be selected.As a key tool in machining, the performance and quality of machining cutting tools have a decisive influence on the quality of part manufacturing. By rationally selecting tool materials, optimizing tool geometry parameters, strengthening tool use management and maintenance, and combining advanced manufacturing technologies, the quality of part manufacturing can be effectively improved to meet the requirements of modern manufacturing for high precision, high efficiency, and high quality.
