Cutting Tool Sharpening Fixture With Movable Angle Fence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tool sharpening techniques struggle to precisely define and sharpen the desired edge of cutting tools, leading to inefficiencies in restoring sharpness and potentially causing injuries due to unstable support during sharpening.
Innovation Solution
A cutting tool sharpening fixture with a guide supported at two points and an angle fixture featuring a movable fence along a track channel, along with removable wheels on body portions, allows for precise angle setting and secure support of the tool during sharpening, enabling effective edge refinement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sharpening techniques are used, then the process is simple, but the precision of edge definition and sharpening is poor
Solution Approach 1:
The sharpening fixture is divided into distinct functional components: an angle fixture for setting the bevel angle, a guide for positioning the tool, and support points for stable tool holding. Each component performs a specific function, allowing precise edge definition through coordinated operation of segmented elements rather than a monolithic complex device
Solution Approach 2:
The angle fixture allows the desired bevel angle to be set and locked in advance using a fence movable along a track channel with angle apertures. This preliminary angle setting ensures that when sharpening begins, the correct geometry is already established, improving edge definition precision without requiring complex real-time adjustments during the sharpening process
2Reliability
If traditional sharpening support methods are used, then the setup is simple, but the stability during sharpening is poor leading to potential injuries
Solution Approach 1:
The guide incorporates wheels at specific locations (body portions) that contact the tool at precise points. These localized wheel contact points provide stable support exactly where needed during sharpening, improving reliability without requiring a completely complex support structure. The wheels are positioned to support the tool while allowing the cutting edge to engage the abrasive surface
Solution Approach 2:
The wheels act as intermediary elements between the guide and the tool being sharpened. Rather than direct contact between the guide and tool, the wheels mediate the support function, providing stable, low-friction contact that enhances sharpening stability and reduces the risk of sudden movements or injuries while maintaining a relatively simple overall structure
3Adaptability or versatility
If the fence is fixed in position, then the structure is simple, but the angle adjustment capability is limited
Solution Approach 1:
The fence is made movable along the track channel, allowing dynamic adjustment to different angle positions. Angle apertures at specific locations enable the fence to be positioned at various angles and locked in place. This dynamic capability provides adaptability for different sharpening applications while the track channel guidance keeps the mechanism relatively simple, avoiding complex adjustment systems

AI summary
A cutting tool sharpening fixture system and method of use is provided. More particularly, the cutting tool has a sharpening guide that is supportable at two points while sharpening and the cutting tool has an angle fixture. The angle fixture has a fence that is movable along a track channel to set an angle. The sharpening guide with wheels on two body portions are removable from the angle fixture.
