Zusammenfassung:The drum-shaped milling cutter comprises a cutter handle part and a cutting part, the cutting part comprises a ball head cutting edge and a side edge, the ball head cutting edge is arranged at a cutter point of the drum-shaped milling cutter, the outer contour of the side edge is in a drum shape, and the side edge is arranged between the ball head cutting edge and the cutter handle part. The side edge comprises a plurality of spiral cutting edges formed by spiraling around the central axis of the cutter handle part, the distance between the side edge and the central axis of the cutter handle part on the radial section of the drum-shaped milling cutter is gradually increased in the direction from the cutting part to the cutter handle part, and the cutter core thickness corresponding to the side edge is gradually increased along with the diameter of the side edge; the included angle between the rake face and the base face of the spiral blade in the orthogonal plane is a groove rake angle, and when the diameter
