1. Determine the primary technical parameters of the milling cutter:
The main parameters of the carpenter milling cutter: tool outer diameter, machining thickness, central aperture Other technical parameters: number of teeth, direction of rotation, speed of rotation, feed rate, clamping method, tooth material.
2. Select the structure method of the milling cutter
According to the nature and requirements of the cutting target, the overall milling cutter, the welding integral milling cutter, the device milling cutter and the combined milling cutter are generally considered from the technical and economic aspects.
3. Selection of milling cutter rotation direction
The direction of rotation of the milling cutter is determined according to the direction of rotation of the machining spindle and the relative orientation of the cutter shaft and the feed workpiece. Whether it is an integral milling cutter or a device milling cutter, the inclination of the cutting edge relative to the radius of the milling cutter selects the milling cutter. Direction of rotation.
4. Selection of milling cutter cutting amount
The cutting amount of the milling cutter includes the cutting speed of the milling cutter, the feed rate of the workpiece and the milling depth. The cutting speed of the milling cutter depends on the milling cutter speed and the radius of the milling cutter. The feed rate of the workpiece depends on the quality of the machined surface. The surface roughness of the workpiece to be cut depends largely on the feed per tooth of the milling cutter during the cutting process. The feed per tooth is too large, the machining surface is too rough, the feed per tooth is too small, and the machined surface will burn. The focus phenomenon, so the feed per tooth of the milling cutter is necessary.
5. Stability of milling operation
The stability of the milling operation is the basis for ensuring the machining accuracy and the quality of the machined surface. This includes two aspects: First, the milling cutter vibrates in the cutting process because of external force; Secondly, the milling cutter deforms under the effect of external force.
6. Safety of milling cutter processing
The safety of milling cutters includes the rotation speed of the milling cutter, the thickness of the chip, the height constraint of the profile cutter and the thickness and extension of the milling cutter.
