How to choose the right cutting amount for the milling cutter

As far as possible, the end milling cutter should choose a large amount of back-belt cutter, and then choose a larger feed amount. Factors that affect the cutting volume include tool material, tool geometric parameters, workpiece material, process type, processing procedure, specific use conditions, such as cutting fluid, machine tools, chucks, etc., even if many fans ask about cutting volume parameters, they are actually There is no accurate answer, so there are generally three methods for determining the cutting amount.

One is to check the feed rate, cutting speed, and tool usage time by checking the manual. The data in the manual can only be used as a reference. The data in the manual is a mathematical model made by cutting tests under specific conditions. The specific use conditions and test conditions are different from our actual use conditions. Certain modifications must be made according to the actual processing conditions, and during repeated use, the processing effects should be adjusted appropriately according to the processing conditions to obtain the best cutting usage.

The second is to consult the product catalog of the tool manufacturer. The product brochure recommends the corresponding cutting speed and feed rate while introducing the product. It will also be specially stated that it must be adjusted according to the actual situation when used.

The third is the cutting test. This method can obtain a reasonable cutting amount, and at the same time, it is relatively expensive. If the processing order is not large, it is not recommended to try. The test conditions should be the same as the actual situation as much as possible, and the cutting amount obtained is more accurate.
