Reinforced Tool Holder Structure for Precise Cutting Force Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders are not optimized for cost-effective production while ensuring precise and stable positioning of cutting tools during machining, as they are often made of cheaper materials that fail to withstand cutting forces effectively, leading to tool bending and reduced tool life.
Innovation Solution
A tool holder design with a basic shape reinforced by material accumulations at specific locations to absorb cutting and passive forces, featuring a framework structure that minimizes weight and allows for efficient material usage, with ribs and cavities strategically placed to manage forces during machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tool holders are made solidly to withstand cutting forces, then strength and stability are improved, but weight increases and material costs increase
Solution Approach 1:
The patent applies local quality by reinforcing only specific regions of the tool holder where cutting forces are maximum. The support structure includes selectively positioned ribs and material accumulations at geometric locations subjected to highest loads, while other areas maintain a lighter framework construction. This localized reinforcement achieves the required strength without uniformly increasing the overall weight of the tool holder.
2Strength
If tool holders are made solidly to withstand cutting forces, then strength and stability are improved, but material costs increase
Solution Approach 1:
The patent applies local quality by reinforcing only specific regions of the tool holder where cutting forces are maximum. The support structure includes selectively positioned ribs and material accumulations at geometric locations subjected to highest loads, while other areas maintain a lighter framework construction. This localized reinforcement achieves the required strength without uniformly increasing the overall weight of the tool holder.
Solution Approach 2:
The patent applies segmentation by dividing the tool holder into a framework structure with distinct support regions. The support structure is segmented into multiple ribs positioned at specific geometric locations, allowing material to be concentrated where needed rather than distributed uniformly throughout the entire holder.
3Strength
If cutting tools are made of hard metal to withstand cutting forces, then strength is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies local quality by reinforcing only specific regions of the tool holder where cutting forces are maximum. The support structure includes selectively positioned ribs and material accumulations at geometric locations subjected to highest loads, while other areas maintain a lighter framework construction. This localized reinforcement achieves the required strength without uniformly increasing the overall weight of the tool holder.
4Ease of manufacture
If tool holders use cheaper steel material, then manufacturing cost decreases, but ability to withstand cutting forces deteriorates
Solution Approach 1:
The patent applies local quality by reinforcing only specific regions of the tool holder where cutting forces are maximum. The support structure includes selectively positioned ribs and material accumulations at geometric locations subjected to highest loads, while other areas maintain a lighter framework construction. This localized reinforcement achieves the required strength without uniformly increasing the overall weight of the tool holder.
Solution Approach 2:
The patent applies composite materials by combining framework structure with selectively positioned support elements. The tool holder integrates a lightweight framework base material with strategically placed reinforcement ribs and material accumulations, creating a composite structure that achieves high strength-to-weight ratio and optimized force distribution.

AI summary
The invention relates to a method for shaping a tool holder (10) or tool base holder (101), and to such a tool holder or tool base holder which, according to the invention, has a basic shape designed to adequately support the cutting tool or the cassette or the tool holder in its resting state, i.e., without being subjected to any machining operation, wherein this basic shape is reinforced by material accumulations only at those geometric locations that are stressed as abutments by forces occurring during machining, namely cutting forces and secondary forces. The invention also relates to a tool holder or tool base holder.
