Milling, as a crucial process in machining, is evolving towards precision milling, multi-axis milling, and adaptive milling.
CNC milling utilizes CNC machine tools and milling cutters to continuously cut workpieces to produce parts of various shapes. Compared to traditional milling methods, it offers higher efficiency and greater flexibility. Common tool materials include high-speed steel, cemented carbide, and ceramics.
High-speed milling is an advanced manufacturing technology. Its cutting speed and feed rate are significantly higher than traditional machining, representing a fundamental leap in cutting performance. High-speed cutting machine tool spindle speeds range from 10,000 to 100,000 m/min. Commonly used tool materials include PCD (polycrystalline diamond), cubic boron nitride (CBN), ceramic tools, and coated cemented carbide.
Five-axis milling technology can be used for the efficient and high-precision machining of complex spatial curved surface parts, such as aero-engine impellers and turbine blades. Its machining process involves key technologies such as geometric-mechanical integrated simulation to ensure machining accuracy. Micromilling, fly cutter milling, and vibration-assisted milling technologies, due to their high efficiency, high precision, and high flexibility, can be used to prepare micro-textured surfaces with specific functions.
Robotic milling utilizes industrial robots for machining, offering advantages such as high dexterity, high reconfigurability, and low cost. It is suitable for machining large-sized, customized workpieces; however, its rigidity is generally lower than that of traditional machine tools, making it prone to chatter.
