Cutting Parameters Of Milling Cutter In CNC Machining - PTJ Manufacturing Shop
Cutting Parameters Of Milling Cutter
The cutting speed v (m/min) of the cnc machining cutter is the peripheral speed of the milling cutter. Anyone who does cnc processing knows that setting the cutting parameters of the milling cutter is an important part of processing the qualified machining parts.
There are three ways to express the milling feed:
- The feed rate per minute vf (mm/min) indicates the displacement of the workpiece per minute relative to the milling cutter;
- The feed per revolution f (mm/rev) indicates the relative displacement of the cutter to the workpiece at one revolution per revolution;
- The feed amount per tooth af (mm/tooth) indicates the relative displacement of the workpiece during the time that the milling cutter rotates one tooth.
The cutting speed of carbon steel in high-speed steel milling cutter milling of cnc processing equipment is generally 20-30 m/min (n=7000/D~10000/D); cemented carbide milling cutter can reach 60-90 m/min (can Estimated by 3 times high speed steel milling cutter).
