What's Wrong With Vibration Lines Appearing During CNC Machining Center Processing
Nov 07, 2023
Vibration patterns often appear in CNC machining centers during machining. The main reasons for the occurrence of vibration marks are as follows:
1. The rigidity caused by external factors includes the rigidity of the tool handle, boring bar, boring head, and the middle connecting part. Because it is cantilever machining, especially for small holes, deep holes, and hard workpieces, external rigidity is particularly important.
2. The rigidity and dynamic balance caused by external factors are relative to the rotational axis, and the mass imbalance caused by external factors leads to the occurrence of vibration patterns during rotation due to the unbalanced centrifugal force. Especially during high-speed machining, the dynamic balance of things has a significant impact.
3. The fixed rigidity of the workpiece itself or the workpiece, such as some smaller and thinner components that lack their own rigidity or cannot be adequately fixed with reasonable press fixtures due to the shape of the workpiece.
4. The shape of the blade tip, the leading angle, the main deviation angle, the radius of the blade tip, and the shape of the chip groove can all lead to different cutting forces.
5. The selection of cutting parameters includes cutting speed, feed rate, feed rate, and cooling method.
6. The rigidity of the spindle itself, the function of bearings and gears, and the rigidity of the connection between the spindle and the tool holder in CNC machining centers.
7. Vibration patterns can occur due to reasons such as mismatched rigidity of CNC system drivers.
