Why CNC machinining chatter could mean inconsistent dimension ?

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.
