Cutting Tool Blade Orientation Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary cutting tools face inefficiencies due to the need for complex setup and measurement to maintain the relative orientation of cutting edges, leading to suboptimal performance when the first and second cutting edges wear down at different rates.
Innovation Solution
A cutting tool design featuring a locking mechanism that secures a blade with adjustable orientation relative to teeth, allowing for easy replacement and maintenance of cutting edges without requiring precise setup, ensuring consistent performance by maintaining the desired spacing and alignment between the blade and teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex setup and measurement procedures are used to maintain relative orientation of cutting edges, then manufacturing precision is improved, but device complexity and time consumption increase
Solution Approach 1:
The cutting tool is divided into modular components: a body with teeth and a separate blade assembly. This segmentation allows the blade to be independently positioned and secured at predetermined locations without requiring complex measurement procedures, as the modular design inherently maintains proper relative orientation between cutting edges.
Solution Approach 2:
The blade is pre-positioned and secured to the body at predetermined locations during manufacturing or initial setup. This preliminary action ensures that the relative orientation of cutting edges is established in advance, eliminating the need for complex setup and measurement procedures during subsequent operations or maintenance.
2Manufacturing precision
If complex setup and measurement procedures are used to maintain relative orientation of cutting edges, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The blade is pre-positioned and secured to the body at predetermined locations during manufacturing or initial setup. This preliminary action ensures that the relative orientation of cutting edges is established in advance, eliminating the need for complex setup and measurement procedures during subsequent operations or maintenance, thereby significantly reducing time loss.
Solution Approach 2:
The locking mechanism allows for quick adjustment and securing of the blade at predetermined locations. This dynamic capability enables rapid blade replacement and repositioning without requiring time-consuming measurement procedures, maintaining manufacturing precision while minimizing time loss during blade changes.
3Manufacturing precision
If cutting edges are secured in fixed positions, then manufacturing precision is improved, but adaptability decreases
Solution Approach 1:
The locking mechanism is designed to secure the blade at multiple predetermined locations around the body's circumference. This dynamic system allows the blade to be positioned and locked at different orientations depending on the specific cutting application, providing adaptability while maintaining precise spacing through the predetermined location design.
Solution Approach 2:
The cutting tool body with its locking mechanism is designed to accommodate the blade in multiple predetermined positions, making the tool versatile for different cutting applications. The same basic structure serves multiple functions by allowing blade repositioning, thereby maintaining manufacturing precision while enhancing adaptability.

AI summary
A blade for a cutting tool. The cutting tool can be supportable on a spindle of a power tool. The blade can include a blade body removably supportable on the cutting tool and being moveable with the cutting tool relative to the power tool for cutting a workpiece. The blade can further include a first cutting edge extending outwardly from the blade body and a second cutting edge extending outwardly from the blade body. When the blade is supported in the cutting tool, the first cutting edge can extend radially across an end of the cutting tool and the second cutting edge can be positioned adjacent an outer circumference of the cutting tool.
