How to choose cutting tools for CNC machining?

In CNC Machining, selecting suitable cutting tools is crucial as it directly affects machining quality, efficiency, and cost. Here are some key factors to consider when choosing CNC machining tools: 1. Material selection: Choose tool materials based on the type and hardness of the machining material. For soft materials such as aluminum alloy, high-speed steel cutting tools can be chosen; For hard materials such as stainless steel or titanium alloy, it is necessary to choose more wear-resistant hard alloy cutting tools or ceramic cutting tools. 2, Tool Geometry: The geometric shape of the tool, such as the radius of the tool tip arc, rake angle, and rake angle, directly affects the machining quality and cutting force. Suitable tool geometries need to be selected based on processing requirements and material characteristics. 3. Tool size: The size of the tool should be selected based on the size and shape of the workpiece being machined. Cutting tools that are too large or too small can affect machining accuracy and efficiency. 4. Tool coating: Tool coating can improve the wear resistance and cutting performance of tools. Choose suitable coatings as needed, such as titanium alloy coatings, aluminum oxide coatings, etc. 5. Processing parameters: Processing parameters such as cutting speed, feed rate, and cutting depth need to be matched with the tool. Excessive or insufficient machining parameters can lead to rapid tool wear or poor machining quality.
