The principle of choosing CNC machining tools

CNC machining tool life is closely related to the cutting volume. When formulating the cutting amount of CNC machining tools, first choose a reasonable CNC machining tool life, and determine the reasonable CNC machining tool life according to the optimization goal. Generally divided into two types: precision CNC machining tool life with the highest productivity and precision CNC machining tool life with the lowest cost. The former is determined based on the goal of the least single-piece man-hours, and the latter determines the process cost based on the goal of the lowest single-piece man-hours.

When choosing the life of precision CNC machining tools, you can choose according to the complexity of precision CNC machining tools, manufacturing costs, and sharpening conditions. The life of complex and precision CNC machining tools should be higher than that of single-edged tools. For machine-clamped indexable CNC machining tools, due to the short tool change time, to give full play to its cutting performance and improve production efficiency, the life of CNC machining tools can be selected to be lower, generally 15-30min. For multi-tools, combined machine tools, tool installation, tool change, and tool adjustment more complex CNC machining machine tools, the life of the CNC machining machine tool is higher, especially to ensure the reliability of the CNC machine tool. When the productivity of a certain process in the workshop limits the entire When the productivity of the workshop is improved, the CNC machining tool life of this process should be lower. When the cost of the whole plant shared by a certain process unit time is relatively large, the life of the CNC machining tool should also be selected to be relatively low. To ensure that at least one pass is completed during the finishing of large parts, and to avoid changing the tool during the cutting process, the life of the CNC machining tool should be determined according to the accuracy and surface roughness of the part. Compared with ordinary machine tool processing methods, CNC machining puts forward higher requirements on tools. It not only requires good quality and high precision, but also requires stable dimensions, high durability, and easy installation and adjustment. Meet the high-efficiency requirements of CNC machining machine tools. The CNC machining tools selected on the CNC machining machine tools often use tool materials suitable for high-speed cutting (such as high-speed steel, ultra-fine grain cemented carbide), and use indexable inserts.

Choose CNC machining tools for CNC turning

CNC machining turning tools used generally are divided into forming turning tools, pointed turning tools, arc turning tools, and three categories. Forming turning tools are also called prototype turning tools, and the contour shape of the machined parts is completely determined by the shape and size of the cutting edge of the turning tool. In CNC machining turning processing, common forming turning tools include small radius arc turning tools, non-rectangular turning tools, and threading tools. In CNC machining, the turning tool should be used as little as possible or not. A pointed turning tool is a turning tool characterized by a straight cutting edge. The tip of this type of turning tool is composed of linear main and secondary cutting edges. The method of selecting geometric parameters (mainly geometric angle) of the pointed turning tool is the same as that of ordinary turning but should be combined with the characteristics of CNC machining (such as processing route). Machining interference, etc.) to be fully considered, and the strength of the tooltip itself should be taken into account.
