Multi-Pocket Insert Adaptor for Deeper Parting-Off Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insert adaptors for parting off operations are limited by reduced cutting depth and increased material wastage due to the number of pockets and the width of cutting edges, and they require complex manufacturing processes, which affect the longevity and efficiency of the tool.
Innovation Solution
An insert adaptor with a central index axis and a peripheral surface featuring three to five pockets, designed to resiliently hold cutting inserts, allowing for increased pocket life and reduced material wastage, while maintaining structural strength and chip evacuation space, and utilizing a solid construction with straight bearing surfaces for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the number of pockets in the insert adaptor is increased from two to three or more, then the pocket life and overall tool lifetime are improved, but the cutting depth capability is reduced due to the width of cutting edges occupying more space on the peripheral surface
Solution Approach 1:
The adaptor peripheral surface is segmented into multiple pockets (three or more) arranged circumferentially, allowing multiple cutting inserts to be positioned around the adaptor. This segmentation enables successive use of multiple inserts along the cutting path, extending the adaptor's operational lifetime while managing the space constraint through circular distribution of pockets.
2Productivity
If three or more pockets are formed on the adaptor peripheral surface, then the productivity is improved through increased pocket life and successive insert use, but the manufacturing cost increases due to the complexity of forming additional pockets
Solution Approach 1:
The adaptor body serves multiple functions: it provides the structural support for the tool, contains all the pockets for multiple inserts, and acts as the indexing mechanism carrier. By integrating these functions into a single component with three or more pockets, the design achieves multi-functionality that improves productivity while managing manufacturing complexity through consolidation rather than assembly of multiple separate parts.
3Strength
If cemented carbide inserts with greater width are used to reduce material wastage in deep parting cuts, then the structural strength is improved, but the adaptor thickness must be increased, which may be disadvantageous for certain operations
Solution Approach 1:
The solution employs composite material construction where cemented carbide inserts (providing high strength and wear resistance) are mounted in pockets of a metal adaptor body (providing toughness and structural support). This composite approach allows the use of wider, stronger carbide inserts for deep cuts while the metal adaptor provides the necessary structural framework without requiring excessive thickness, as the two materials complement each other's properties.

AI summary
An insert adaptor for parting off including an adaptor index axis and parallel adaptor first and second sides connected by an adaptor peripheral surface which extends peripherally around the adaptor. The adaptor peripheral surface is formed with at least three pockets and bearing surfaces extending between the pockets. Each of the pockets comprises resilient upper and lower clamp surfaces.
