Milling processing cutting amount includes the main axis 

Motor speed, feed speed, back -eating knife volume, and side eating. The amount of feed processing of milling refers to the relative displacement of the tool and the tool in the direction of the workpiece and the tool, and its unit is MM / R. The feed speed is the relative displacement of the workpiece and milling cutter in the unit time, and its unit is MM/min. The size of the cutting dosage has a significant impact on cutting force, cutting power, tool wear processing center, processing quality and processing costs. When selecting the amount of cutting in the number of machine tool accessories, it is to give full play to the performance of the machine tool and the cutting performance of the tool, and make the cutting efficiency high and the processing cost of the cutting efficiency.

     (1) Selection of the amount of knife/(end milling/) or side of the sideways/(round permeal/)

Eat the amount of cutting knife, the size of the cutting layer measured in the milling axis parallel, and the unit is mill. When end milling, o. For the depth of the cutting layer; when the periability, OT/) is the width of the processed surface.

     Eat the amount of knife on the side. The size of the cutting layer measured vertically at the milling cutter axis, the unit is MM. O. The width of the processed surface during end milling is the depth of the cutting layer when the circular milling.

     The selection of the amount of the knife of the knife or the side machine tool is mainly determined by the processing waste and the requirements of the surface quality.

     (1) When the surface roughness value of the workpiece is large, if the amount of processing the processing of the circular milling is less than 5mm, and the amount of processing the processing of the end milling is less than 6mm, the rough milling can meet the requirements. However, when the remaining amount is large, the system of the process processing center is poor or the machine tool is insufficient, it can be completed a few more times.

     (2) In the case of the roughness value of the workpiece, it is small, and it can be carried out in two steps: crude milling and semi -essence milling. Eat the knife volume or the amount of knives on the side during rough milling. Leave 0.5-1 after coarse milling. The amount of OMM is removed during semi -essence milling.

     (3) For the requirements of the surface roughness of the workpiece, it is required to be carried out in three steps: crude milling, semi -essence milling and refined milling. Eat the amount of knife or side knife for 1.5-2mm when the semi -essence milling, and eat the knife amount of 0.3-0.5mm per week during refined milling. Essence
