Variable Cutting Angle for Burr-Free Electrode Edges

The patent applies the dynamics principle by making the cutting angle variable rather than fixed. The upper blade is equipped with a tilting mechanism that allows it to rotate around a hinge part, enabling the cutting angle to change dynamically during the cutting process. This dynamic adjustment capability allows the system to adapt to different cutting conditions and produce higher quality edges without requiring a completely complex redesign of the cutting device architecture.

The patent implements parameter changes by varying the cutting angle parameter during the cutting operation. Through the tilting mechanism with the hinge part and actuator, the cutting angle is changed from a fixed value to a variable parameter that can be adjusted in real-time. This parameter change enables better control over the cutting process, reducing burrs and sharp corners while maintaining a relatively simple overall device structure.

The patent applies the spheroidality principle by using a curved first cutting edge instead of a straight edge. This curved geometry naturally varies the cutting angle as the blade moves through the material, eliminating the need for complex tilting mechanisms. The curved shape is simpler to manufacture than precision-machined variable-angle mechanisms, while still achieving superior cut edge quality by progressively changing the effective cutting angle throughout the cut.

The curved cutting edge design embodies the curvature principle, where a simple geometric shape (the curve) inherently provides the variable cutting angle function. This approach trades the complexity of active angle-adjustment mechanisms for a passively variable angle achieved through the blade's geometry itself, which is easier to manufacture and maintains high reliability.
