Thread milling refers to the process of milling threads.
The research work of thread milling mainly focuses on the theoretical and technological aspects. Thread milling generally involves multiple passes, divided into roughing and finishing, but for difficult-to-machine materials, when milling
For the thread milling of superalloy materials, the expression method of cutting thickness is analyzed, and the expression method of cross-sectional area formed by two adjacent passes is established. Based on this, the superalloy
Thread milling experimental materials
The high-temperature alloy GH4169 is used as the experimental material. It has the advantages of high strength, good corrosion resistance, and strong thermal stability. It is a widely used component material in the aerospace and aerospace fields. 30mm.
Main experimental device for thread milling
(1) Machine tool and measuring equipment: machine tool (DMG ULTRASONIC20linear five-axis machining center), dynamometer (Kistler9265B dynamic dynamometer).
(2) Tool material: Carbide solid three-tooth thread milling cutter (TiAlCN coating, helix angle 15 °).
