①When machining curved parts, in order to ensure that the cutting edge of the tool and the machining contour are tangent at the cutting point, and to avoid the interference between the cutting edge and the contour of the workpiece, generally use a ball nose cutter, a two-edged milling cutter for rough machining, semi-finishing and finishing With a four-edged milling cutter, the number of cutting edges is also related to the diameter of the milling cutter
②When milling a larger plane, in order to improve production efficiency and improve the roughness of the machined surface, a blade inlaid disc face milling cutter is generally used.
③General-purpose milling cutters are generally used when milling facets or stepped surfaces
④When milling the keyway, in order to ensure the dimensional accuracy of the slot, a two-edged keyway milling cutter is generally used.
⑤ During hole processing, hole processing tools such as drills and boring tools can be used
Keyway milling cutter difference

1. The keyway milling cutter cannot process the plane, while the end mill can process the plane.
2. The keyway milling cutter is mainly used for processing keyway and groove, and the keyway milling cutter is very useful for milling keyway. For example, a 6MM end mill and a keyway milling cutter 6MM are more likely to be slotted than a 6MM end mill, and the end mill is easy to break, while the keyway milling cutter can pass through it in one go.
3. The cutting amount of the keyway milling cutter is larger than that of the end mill.
The use of end mills—–face milling

End mills can be used for face milling. However, because its main declination angle is 90°, the force on the tool is mainly radial force in addition to the main cutting force, which is easy to cause deflection and deformation of the tool bar, and also easy to cause vibration, which affects the processing efficiency. Therefore, in addition to similar to thin-bottomed workpieces Except for special reasons such as the need for small axial forces or the occasional reduction in tool inventory for face milling, end mills are not recommended for machining flat surfaces without steps.
