Blisk technology processing has been used in our country and even other countries, and is mainly used in military and civil aviation engines in various countries. Blisk processing technology is mainly a new structural part designed to meet the needs of high-performance aero engines. Due to the high precision of blisk geometry and strict technical requirements. In machining, in order to ensure uniform finishing allowance, we usually use CNC lathe machining centers. This processing technology mainly involves two major types of equipment, namely controlled lathes and five-coordinate machining centers. The former is used to process the disc part, the machining center is used to process the blade part, and the latter requires the compound motion of five axes to complete the processing of the blade. The choice in this processing technology is also very important, and milling tools need to be selected rationally. So how do we make a choice about it? Next, let me briefly introduce it to you.

1. Structural selection. The choice of milling tools is actually to choose tools with larger diameters as much as possible, which not only ensures the rigidity of the tools, but also helps improve processing efficiency. And the length should be appropriate to avoid interference with the blade profile.

2. Tool type selection. During the process, the processing area between the blades is narrow, the movable range of the tool is small, and the processing area constraints are complex. Because the blade is longer, the aspect ratio of the tool is increased, and the deformation and vibration problems caused by processing stress are difficult to solve, seriously affecting the processing efficiency and surface quality.

3. The selection of tool parameters, due to the restriction of the channel, requires the tool diameter to be small and the tool shank to be long, which will produce vibration when subjected to cutting force. When the length of the tool is short and the tool's rigidity is strong, the tool works in the stiffness control zone.
