In precision part machining, thread CNC milling is a common technique. Thread is a type of protrusion and groove with a spiral shape, commonly used for connecting and fixing parts. Thread CNC milling can be achieved through CNC milling machines.
The key to CNC milling of threads lies in determining the machining path and process parameters. Firstly, CAD (computer-aided design) modeling is required to draw the geometric shape of the thread. Then, the machining path is generated using CAM (Computer Aided Manufacturing) software, including cutting profile and feed rate information.
In the actual machining process, it is necessary to choose appropriate cutting tools and fixtures. Common cutting tools include thread milling cutters and thread cutting tools. Thread milling cutters are suitable for larger diameter and shallower thread processing, while thread cutting tools are suitable for smaller diameter and deeper thread processing. The selection of fixtures should ensure that the workpiece is firmly fixed to avoid vibration and errors during the machining process.
During the machining process, it is necessary to set cutting parameters reasonably, including cutting speed, feed rate, and cutting depth. The selection of these parameters should be determined based on the workpiece material and thread size to ensure machining quality and efficiency.
In summary, thread CNC milling is one of the commonly used techniques in precision part machining. Through reasonable machining path planning, tool selection, and cutting parameter settings, high-quality thread machining can be achieved.
