Cutting Tool Holder with Recessed Coolant Pocket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools, such as milling cutters, face inefficiencies in coolant distribution and chip disposal, leading to reduced cutting edge durability and uneven machining surfaces due to inadequate coolant collection and dispersion around the cutting edge.
Innovation Solution
A cutting tool design featuring a holder with inflow and outflow ports, a first flow path, and a recessed portion in the pocket to collect and efficiently disperse coolant, ensuring effective cooling of the cutting edge and stable chip disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coolant is supplied via a simple flow path, then the structure is simple, but coolant distribution and collection around the cutting edge are inadequate
Solution Approach 1:
The pocket is divided into a placement portion for the insert and a cutout portion for chip disposal, with the cutout portion further segmented into multiple recessed portions. This segmentation allows coolant to be distributed to multiple specific locations around the cutting edge, improving cooling efficiency without requiring a completely complex new structure
Solution Approach 2:
The recessed portions are strategically positioned at specific locations where coolant is most needed for cooling the cutting edge and collecting chips. By concentrating coolant flow at these critical local points rather than distributing it uniformly, the system achieves superior cooling effectiveness with a relatively simple overall structure
2Reliability
If the pocket includes a cutout portion with recessed portions, then coolant collection and dispersion are improved, but the pocket structure becomes more complex
Solution Approach 1:
The cutout portion is divided into multiple recessed portions that are distributed around the placement portion. This segmentation enables coolant to reach multiple areas around the cutting edge simultaneously, improving overall cooling efficiency while keeping each individual recessed portion structurally simple
Solution Approach 2:
The cutout portion serves multiple functions: it acts as a chip disposal area and simultaneously creates multiple recessed portions that function as coolant collection and distribution points. This multi-functionality improves cooling efficiency without requiring separate dedicated structures for chip disposal and coolant distribution
3Temperature
If coolant flow path is extended to reach cutting edge, then cooling effectiveness improves, but pressure loss increases
Solution Approach 1:
The recessed portions are positioned to receive coolant before it needs to travel to the cutting edge. By pre-positioning coolant in these recessed areas, the system reduces the distance coolant must travel under pressure, minimizing pressure loss while ensuring coolant is already in position to effectively cool the cutting edge when needed
