Understanding the Impact of Tool Chatter Marks on Dimensional Stability in CNC Machining
-
Surface Finish Degradation:
Chatter can cause an uneven surface finish,making it difficult to achieve the desired dimensions with precision.
-
Tool Deflection:
The vibration can lead to tool deflection, where the Cutting tool does not follow the intended path accurately. This can result in dimensions that are off from the intended design.
-
Material Removal Variability:
Chatter can cause inconsistent material removal rates. In some areas, more material might be removed than intended, while in others, less material might be removed, leading to dimensional inaccuracies.
-
Tool Wear:
Excessive chatter can lead to premature tool wear, which can change the cutting geometry over time. This can affect the dimensions of the CNC machined parts.
-
Stress Concentrations:
Chatter can introduce stress concentrations into the material of workpiece , which can lead to deformation or warping of the part, further affecting its dimensional accuracy.
