Waterfall profile
The waterfall profile describes a uniform edge rounding with a continuous transition between surface and edge.
The goal is a reproducible edge condition with controlled material removal along the workpiece edge.
Formation of a waterfall profile
A waterfall profile is created through uniform tool engagement and controlled edge processing during mechanical post-processing.
Crucial factors are stable process parameters, reproducible tool guidance, and a homogeneous initial state of the component edge.
Factors influencing the edge profile
- tool intervention
- contact pressure
- tool wear
- material properties
- process stability
Effects on edge quality
A uniform waterfall profile improves the reproducibility of edge processing and stabilizes subsequent coating and manufacturing processes.
Especially when there are high demands on coating capability and component feel, a homogeneous edge condition has a positive effect on component quality.
Typical quality effects
- consistent edge quality
- stable coating conditions
- improved component feel
- reduced post-processing effort
- reproducible edge processing
Relationship to edge rounding
In the edge rounding process step, material is processed in a controlled manner at the workpiece edge to create defined edge profiles and a reproducible transition between surface and edge.
A uniform waterfall profile is considered the target state for stable and reproducible edge processing.
Difference between waterfall profile and fingernail effect
The waterfall profile describes a uniform and reproducible edge contour. In contrast, the fingernail effect describes an asymmetrical edge contour resulting from unstable machining conditions.
Technical differences
- Waterfall profile: uniform material removal
- Fingernail effect: asymmetrical edge contour
- Waterfall profile: reproducible edge condition
- Fingernail effect: unstable edge geometry
