Segmented Tipped Saw Blade Bevel Layout for Low-Resistance Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional segmented cutting type tipped saw blades face challenges in reducing cutting resistance and noise while maintaining a smooth cut surface, as they often concentrate cutting power on specific tips and generate excessive noise during operation.
Innovation Solution
The segmented cutting type tipped saw blade features a disc-shaped metal base with a specific arrangement of tips, including first and second end tips, and ridge tips, each with a top bevel surface extending from the tip end to the other end, with bevel angles between 3° and 10°, distributing cutting power evenly and reducing friction and noise.

1Object-affected harmful factors
If conventional segmented cutting type tipped saw blades are used, then cutting function is achieved, but cutting resistance and noise are excessive
Solution Approach 1:
The saw blade is divided into multiple segments with different tip profiles (end tips and ridge tips) arranged in a specific pattern around the perimeter. This segmentation allows different portions of the blade to perform different cutting functions, distributing the cutting load and reducing concentrated stress that causes high cutting resistance and noise.
Solution Approach 2:
Different tip profiles are assigned to different locations: end tips at the ends of segments and ridge tips at the ridges between segments. Each tip type has optimized geometry for its specific position, creating local quality variations that reduce friction and cutting resistance while maintaining effective cutting across the entire blade perimeter.
2Object-affected harmful factors
If tips with small contact areas are used, then friction force is reduced, but cut surface smoothness may be compromised
Solution Approach 1:
The cutting edge is segmented into multiple small tip contact points rather than one large continuous contact area. This segmentation reduces total friction while the specific arrangement of end tips and ridge tips ensures smooth cut surface by distributing the cutting action across multiple points that work in sequence.
Solution Approach 2:
The tip profiles are designed with specific geometric parameters (angles, radii, heights) that optimize the balance between contact area and cutting performance. By carefully controlling these parameters, the tips achieve low friction through small contact areas while maintaining smooth cut surfaces through optimized geometry.

AI summary
A segmented cutting type tipped saw blade includes a first ridge tip, a second ridge tip, a first end tip, and a second end tip. A first end of the first end tip, a second end of the second end tip, a tip end of the first ridge tip, and a tip end of the second ridge tip project radially outward. A top bevel surface extending from the first end and a top bevel surface extending from the second end, a first bevel surface and a second bevel surface extending from the tip end of the first ridge tip and a first bevel surface and a second bevel surface extending from the tip end of the second ridge tip each have a top bevel angle of greater than or equal to 3° and less than or equal to 10°.
