Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine reaming tools face challenges in achieving precise and adjustable holding of cutting inserts, requiring cumbersome grinding and precise reinstallation, which limits their versatility and precision in machining cylindrical bores.
Innovation Solution
A machine reaming tool with a base body featuring insert receivers that provide a linear guide for cutting inserts, allowing for precise positioning and fixation without grinding, using a clamping body and asymmetric dovetail guide to compensate for asymmetrical forces and enhance precision, along with an adjustable stop unit and coolant feed system for adaptable machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cutting inserts are removed and reattached to the base body, then the cutting inserts can be reused, but they must be inserted at precisely the same location or ground afresh, increasing time and complexity
Solution Approach 1:
The insert receivers are pre-formed with linear guides during base body manufacturing, eliminating the need for on-site grinding when cutting inserts are reattached. This preliminary preparation enables rapid reinstallation without time-consuming grinding operations.
Solution Approach 2:
The linear guide structure acts as an intermediary mechanism between the cutting insert and base body, providing a precise reference path that ensures accurate repositioning without requiring grinding. The guide geometry mediates the positioning process.
2Adaptability or versatility
If cutting inserts are frequently adjusted to different diameters, then versatility is improved, but the process becomes cumbersome requiring grinding and precise reinstallation
Solution Approach 1:
The linear guides enable dynamic adjustment of cutting insert positions along the guide paths. The clamping bodies can be moved to different locations on the linear guides to accommodate various diameter requirements, providing dynamic adaptability without complex procedures.
Solution Approach 2:
The base body is segmented into multiple insert receivers, each with its own linear guide. This segmentation allows independent adjustment of each cutting insert position, enabling versatile diameter adjustments through simple repositioning rather than complex overall adjustments.
3Manufacturing precision
If a linear guide is formed in the insert receiver, then precise positioning of cutting inserts is achieved, but the base body structure becomes more complex
Solution Approach 1:
The linear guide structure is merged with the insert receiver geometry, forming an integrated component rather than a separate addition. This combining achieves precise positioning while minimizing overall structural complexity by eliminating the need for separate guiding mechanisms.
Solution Approach 2:
The linear guide serves multiple functions: it provides precise positioning, acts as a reference for clamping body movement, and defines the adjustment path. This multi-functionality reduces the need for additional structural elements, maintaining simplicity while achieving precision.

AI summary
A machine reaming tool includes a base body with a plurality of insert receivers with cutting inserts that are inserted therein. The cutting inserts are inserted into insert receivers that each form a linear guide of the cutting inserts in a direction orthogonal to a rotation axis of the machine reaming tool. The linear guide is a prismatic sliding guide such as a dovetail guide. In particular, the dovetail guide is designed asymmetrically.
