Conical Deburring Chamfer Tool With Asymmetric Cutting Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring chamfer tools with multi-cutting edges face difficulties in efficiently removing burrs due to small gaps between adjacent cutting edges, leading to inefficient burr removal.
Innovation Solution
A deburring chamfer tool with a conical working end featuring multiple cutting edges of varying lengths, where each cutting edge slopes from the vertex to the base, and the edges are designed to be operably rotated, allowing for efficient burr removal by optimizing the cutting edge geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cutting edges are used to remove burrs, then burr removal efficiency should improve, but small gaps between adjacent cutting edges cause difficulties in effectively removing burrs
Solution Approach 1:
The conical working end is divided into multiple cutting edges (first and second cutting edges) with different lengths, where each cutting edge operates independently to remove burrs from different locations and orientations, allowing simultaneous multi-point deburring without interference
Solution Approach 2:
The cutting edges are designed with asymmetric lengths relative to the conical vertex, where the first cutting edge has a different length than the second cutting edge. This asymmetric configuration allows each cutting edge to engage burrs at different positions and angles, overcoming the limitation of uniform multi-edge designs where small gaps prevent effective burr removal
2Device complexity
If a single cutting edge is used to simplify the tool design, then device complexity is reduced, but burr removal efficiency deteriorates
Solution Approach 1:
The tool incorporates multiple cutting edges segmented along the conical surface, each capable of independent burr removal. This segmentation provides multi-point contact capability that significantly improves burr removal efficiency compared to single-edged tools, while maintaining a unified conical structure
Solution Approach 2:
The cutting edges are arranged on a conical surface, utilizing the curved geometry to distribute cutting edges across different spatial positions. This curved arrangement allows multiple cutting edges to engage burrs simultaneously at various locations without requiring a complex multi-component structure, achieving high efficiency with relatively simple design

AI summary
A deburring chamfer tool has a main body including a working end for engaging a workpiece to be deburred. The working end is of a conical shape and has a first and a second cutting edge respectively extending lengthwise with reference to different slant reference lines which delimit the conical shape. Each of the first and the second cutting edges slope from a first end adjacent to the vertex of the conical shape to a second end adjacent to the base of the conical shape in a first length and a second length respectively. The second length is smaller than the first length.
