Cutting Tool Elongated Coolant Outlet with Bend
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools with shaped coolant outlets lack an efficient design for uniformly delivering coolant to elongated cutting edges, leading to inadequate cooling and potential tool wear, and often require multiple coolant outlets with spaced support areas that can lead to inefficiencies and increased coolant usage.
Innovation Solution
A cutting tool with an elongated coolant outlet featuring a medial line with a bend, allowing for a single compact coolant outlet that can be configured to match the curvature of the cutting edge, providing uniform coolant supply and reducing coolant usage by directing it only to the cutting edge, thus prolonging tool lifespan and improving cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple coolant outlets with spaced support areas are used, then coolant coverage area is increased, but device complexity and coolant usage increase
Solution Approach 1:
The coolant outlet is segmented into multiple spray zones along its elongated structure, with each section directing coolant to specific portions of the cutting edge. This allows a single outlet to function as multiple targeted outlets, covering the entire cutting edge area without requiring multiple separate outlet components.
Solution Approach 2:
Multiple coolant delivery functions are merged into a single elongated outlet structure. The outlet combines multiple spray directions and coverage areas into one integrated component, eliminating the need for spaced support areas and multiple separate outlets while maintaining comprehensive coolant coverage.
2Temperature
If concentrated high pressured coolant is dispensed on cutting edge, then cooling efficiency is improved, but uniform distribution along elongated cutting edges is inadequate
Solution Approach 1:
The elongated coolant outlet features locally optimized spray characteristics along its length, with different sections configured to deliver coolant to specific portions of the cutting edge. This ensures that each local area receives appropriate coolant distribution while maintaining overall uniformity across the entire elongated cutting edge.
Solution Approach 2:
The coolant outlet transitions from a point-source or small-area outlet to an elongated linear structure, adding a dimensional aspect that matches the geometry of elongated cutting edges. This dimensional change enables uniform coolant distribution along the entire length of the cutting edge while maintaining concentrated high-pressure delivery.
3Device complexity
If traditional coolant outlets are used, then tool design is simplified, but coolant is not directed precisely to cutting edge leading to increased coolant usage
Solution Approach 1:
The elongated coolant outlet incorporates curved or angled configurations that follow the geometry of the cutting edge. This curved design allows precise directional control of coolant flow along the cutting edge profile, ensuring coolant is delivered exactly where needed rather than following straight-line paths that would miss target areas.
