Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If more portions of the outer periphery of the cutting edge are removed to form slits, then chip discharge ability and cooling effect are improved, but processing efficiency is reduced
Solution Approach 1:
The annular cutting edge is segmented into multiple V-shaped slits distributed around its periphery. Each slit acts as an independent channel for chip discharge and cooling fluid supply, allowing efficient chip removal without requiring excessive material removal that would compromise cutting efficiency.
Solution Approach 2:
The V-shaped slits are positioned specifically in the outer periphery region where chip accumulation and heat generation are most severe. This localized feature provides enhanced chip discharge and cooling exactly where needed, while preserving the cutting edge integrity in other regions.
2Temperature
If more portions of the outer periphery of the cutting edge are removed to form slits, then cooling effect is improved, but mechanical strength is reduced
Solution Approach 1:
Multiple discrete V-shaped slits are distributed around the annular cutting edge, providing adequate cooling channels without creating large continuous voids that would severely compromise structural strength. The segmented approach balances cooling efficiency with mechanical integrity.
Solution Approach 2:
The V-shaped slits have asymmetric geometry with a first surface perpendicular to the rotation direction and a second surface inclined at 30°-60°, optimizing both cooling fluid flow and structural strength distribution around each slit.
3Object-generated harmful factors
If more portions of the outer periphery of the cutting edge are removed to form slits, then chip discharge ability is improved, but mechanical strength is reduced
Solution Approach 1:
The cutting edge is divided into multiple discrete V-shaped slit segments rather than one large continuous opening. This segmentation allows effective chip discharge pathways while maintaining sufficient material between slits to preserve the overall structural strength of the annular grinding stone.
Solution Approach 2:
V-shaped slits are positioned in the outer periphery where chip discharge is most critical, providing localized chip ejection capability while minimizing the impact on overall mechanical strength by concentrating the openings in the region where they are most effective.

AI summary
An annular grinding stone is provided which includes a cutting edge with a plurality of V-shaped slits defined in an outer circumferential portion thereof is provided. Each of the V-shaped slits is defined by a first surface and a second surface of the annular cutting edge. The first surface is positioned rearwardly of the second surface with respect to a direction along which the annular grinding stone rotates, and the second surface is positioned forwardly of the first surface with respect to the direction along which the annular grinding stone rotates. The first surface lies perpendicularly to the direction along which the annular grinding stone rotates at a radially outer end thereof and parallel to thicknesswise directions of the annular cutting edge. The second surface is inclined with respect to the first surface at an angle ranging from 30° to 60°.
