Cutting Tool Holder With Integrated Support And Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools require significant time and labor to index and replace cutting inserts due to the need to remove and reattach fasteners, which is inefficient and costly, especially when dealing with multiple inserts.
Innovation Solution
A cutting tool holder design that incorporates a support element and a fastening member, where the support element and fastening member together occupy at least 15% of the insert seat space, allowing for easier mounting and securing of cutting inserts without the need for frequent disengagement of fasteners, enabling quicker indexing and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fastening system is used with fasteners passing through bores in the cutting insert, then the cutting insert can be securely attached to the tool holder, but the time and labor required for indexing and replacing inserts increases significantly
Solution Approach 1:
The support element is pre-positioned within the insert seat before the cutting insert is mounted. This preliminary positioning creates a ready-made support structure that reduces the complexity of the mounting operation, allowing the insert to be quickly secured without requiring complex fastener manipulation through bores in the insert.
Solution Approach 2:
The fastening system is divided into two independent components: a support element that provides structural support and a separate fastening member that secures the insert. This segmentation allows each component to be optimized independently and simplifies the overall mounting process, as the support element remains in place while the fastening member can be quickly engaged or disengaged.
2Adaptability or versatility
If multiple cutting inserts are used in a cutting tool, then the tool can perform multiple cutting operations, but the total time and labor costs for indexing all inserts increases considerably
Solution Approach 1:
Multiple support elements are pre-positioned in各自的 insert seats within the tool holder before any inserts are mounted. This preliminary setup creates a ready framework that facilitates rapid insert changes, allowing operators to quickly index through multiple inserts without repeatedly manipulating complex fastening systems for each insert.
Solution Approach 2:
Each insert position has its own independent support element and fastening member, allowing inserts to be indexed individually without affecting other positions. This segmentation enables efficient multi-insert operations where each insert can be quickly changed in isolation, minimizing total indexing time across all inserts.
3Reliability
If fasteners are used to secure cutting inserts, then the inserts can be firmly held in place, but the risk of fastener loss during removal increases
Solution Approach 1:
The support element and fastening member are combined into an integrated fastening system where the support element remains permanently positioned in the insert seat while the fastening member engages with it. This merging ensures that the support structure is never lost during insert removal, as it remains anchored in the tool holder, eliminating the risk of fastener loss while maintaining firm holding of the insert.

AI summary
A cutting tool comprising a cutting tool holder and a cutting insert adapted to be mounted thereon. The tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted to receive therein the insert. The seat comprises a support element extending into the insert seat from the base, and a fastening member engageable with the seat. The fastening member is displaceable with respect thereto between a mounting position adapted to allow the insert to be mounted onto the seat and a securing position adapted for securing the insert within the seat. The insert is formed with a securing cavity and when the insert is mounted onto the tool holder and is in the securing position, a portion of the support element and the fastening member is received within the cavity of the insert.
