Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cutting inserts are made replaceable and mounted in holders, then adaptability to different diameters is improved, but manufacturing precision deteriorates due to guidance limitations in slots
Solution Approach 1:
The cutting inserts are made movable within the base body through a linear guide system, allowing dynamic adjustment of the cutting diameter while maintaining precise guidance. The linear guide enables the cutting inserts to be positioned at different radial distances from the rotation axis, providing adaptability to different diameters while ensuring manufacturing precision through constrained linear movement.
Solution Approach 2:
The cutting tool is segmented into replaceable cutting inserts mounted in holders within the base body. This segmentation allows independent adjustment of each cutting insert's position, enabling adaptability to different diameters while maintaining precise guidance through the linear guide system for each insert.
2Adaptability or versatility
If cutting inserts are made adjustable in position, then adaptability to different diameters is improved, but device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The linear guide system allows the cutting inserts to be easily positioned and fixed by the operator without requiring complex adjustment mechanisms. The guide structure itself provides the constraint and guidance, making the adjustment process simple and intuitive while maintaining adaptability to different diameters.
Solution Approach 2:
The linear guide acts as an intermediary between the cutting insert and the base body, providing a simple yet effective mechanism for adjustable positioning. This intermediary structure enables diameter adjustment without requiring complex mechanisms, as the guide constrains the insert to linear movement along the desired path.
3Reliability
If guide section is made significantly longer for reliable guidance, then reliability is improved, but the length of the cutting tool increases
Solution Approach 1:
The linear guide system provides dynamic guidance that is effective over shorter distances compared to traditional long guide sections. The constrained linear movement along the linear guide ensures reliable guidance even with a shorter guide section, reducing the overall tool length while maintaining guidance reliability.
4Adaptability or versatility
If cutting inserts are removed and reattached, then adaptability to different diameters is improved, but loss of time increases due to regrinding requirements
Solution Approach 1:
The linear guide system allows cutting inserts to be removed and reattached at different positions along the guide without requiring regrinding. The adjustable positioning capability enables the same cutting insert to be reused for different diameter reaming operations by simply repositioning it within the linear guide, eliminating time-consuming regrinding processes.

AI summary
A machine reaming tool (1) has a base body (2) with a plurality of cutting inserts (24) containing cutting inserts (3). The cutting inserts (3) are inserted into cutting inserts (24), each of which forms a linear guide for the cutting inserts (3) in a direction orthogonal to an axis of rotation of the machine reaming tool (1). The linear guide is a prismatic sliding guide, in particular a dovetail guide. The dovetail guide is, in particular, asymmetrically designed.
