To understand the milling cutter, you must first understand the milling knowledge

When optimizing the milling effect, the blade of the milling cutter is another important factor. In any milling, if there are more than one blades participating in the cutting at the same time, it is an advantage, but too many blades participating in the cutting at the same time are the disadvantages. It is impossible for a cutting edge to cut at the same time. The required power is related to the number of cutting edges participating in the cutting. In terms of chip formation process, cutting edge load and processing results, the position of the milling cutter relative to the workpiece plays an important role. When face milling, use a milling cutter that is about 30% larger than the cutting width and position the milling cutter close to the center of the workpiece, then the chip thickness does not change much. The chip thickness during cutting is slightly thinner than when cutting at the center.
In order to ensure that a sufficiently high average chip thickness / feed per tooth is used, the number of cutter teeth suitable for this process must be correctly determined. The pitch of the cutter is the distance between the effective cutting edges. According to this value, the milling cutter can be divided into three types-dense tooth milling cutter, sparse tooth milling cutter, special dense tooth milling cutter.
Also related to the thickness of the milled chips is the main angle of the face milling cutter. The main angle is the angle between the main cutting edge of the insert and the surface of the workpiece. The main angles are 45 degrees, 90 degrees and the circular blade. The direction change will change greatly with the difference of the main declination angle: the milling cutter with a main declination angle of 90 degrees mainly produces radial force, which acts in the feed direction, which means that the surface to be processed will not bear too much pressure It is more reliable for workpieces with weak milling structure.
The milling cutter with a main declination angle of 45 degrees has roughly the same radial cutting force and axial direction, so the pressure generated is relatively balanced, and the power requirements of the machine tool are also relatively low. It is especially suitable for short chip materials that produce chipping chips during milling. Artifacts.
The milling cutter with round insert means that the main declination angle changes continuously from 0 to 90 degrees, which mainly depends on the cutting depth. The cutting edge strength of this type of blade is very high. Because the chips generated along the long cutting edge are relatively thin, it is suitable for large feeds. The direction of the cutting force in the radial direction of the blade is constantly changing, and the pressure generated during the processing It will depend on the depth of cut. The development of the geometric geometry of modern blades has the advantages of round cutting blades with a smooth cutting effect, low power requirements for the machine tool, and good stability. It is no longer an effective rough milling cutter, and is widely used in face milling and end milling.
