How to solve the vibration of non-standard cutting tools

How to solve the problem of tool vibration in non-standard cutting tools? The manufacturer will tell you
Non standard cutting tools, made of hard alloy, will directly fracture when subjected to high vibration or machining torque.
If it is a local stress concentration, careful attention should be paid to the parts with stress concentration during design. For parts with significant diameter changes, diagonal transitions or step designs should be added. For slender parts with a large aspect ratio, directly control their deformation and jumping. During design, attention should be paid to avoiding areas prone to stress concentration. For areas with significant diameter changes, diagonal transitions or step designs should be added.
2. Construction of lathe vibration, such as the geometric angle and strength of non-standard cutting tools, as well as the rigidity of workpieces and machine tools; The cutting amount will affect the vibration of the lathe, and reducing the vibration of the lathe is also to reduce the resonance of non-standard cutting tools.
3. Reduce the speed.
4. Adjust the lathe parameters. If it is a surface roughness issue, it can be achieved by changing the geometric angle of the cutting edge, such as increasing the degree of the front and back angles, which will significantly improve the surface roughness of the workpiece. But if the rigidity of the machine tool used is not enough, it is possible that the blunt edge can actually improve the surface roughness. This aspect is very complex and requires analysis of the processing site before reaching a conclusion.
