Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wiper tool has only one or two symmetrical wipers on one tip, then the structure is simple, but the wiper insert loses wiping effect when mounted on different tool holders with different major cutting edge angles
Solution Approach 1:
The cutting part is segmented into multiple wipers (at least three), each with different minor cutting edge angles. This segmentation allows each wiper to be optimized for specific tool holder angles, enabling the insert to adapt to different tool holders by selecting the appropriate wiper orientation.
Solution Approach 2:
The wipers are designed with asymmetric minor cutting edge angles rather than being symmetrical. This asymmetry enables each wiper to correspond to specific major cutting edge angles of different tool holders, allowing the same insert to function correctly with various tool holder configurations.
2Manufacturing precision
If the wiper insert is designed for a specific tool holder angle, then the wiping effect is optimized for that angle, but the same insert cannot be used with other tool holders or for different workpiece parts
Solution Approach 1:
The wiper insert is designed with multiple wipers having different minor cutting edge angles, enabling a single insert to serve multiple functions across different tool holders and workpiece configurations. The polygonal mounting hole with multiple apex corners further enables the same insert to be mounted in different orientations, making it universally applicable to various tool holders and workpiece parts such as outer circles, end faces, and profiling operations.
3Adaptability or versatility
If multiple wipers with different minor cutting edge angles are provided, then the wiper insert can adapt to various tool holders and maintain wiping effect, but the device complexity increases
Solution Approach 1:
Multiple wipers with different minor cutting edge angles are merged into a single integrated cutting part. This consolidation allows the insert to provide multiple wiping functions simultaneously, reducing the need for multiple separate inserts and tool holder changes, thereby managing complexity through integration rather than proliferation of separate components.
4Manufacturing precision
If different types of wiper inserts are used for different tool holders and workpiece parts, then the wiping effect is optimized for each specific application, but the quantity of tools and cost increase
Solution Approach 1:
A single wiper insert design with multiple wipers and a polygonal mounting hole serves multiple applications across different tool holders and workpiece parts. This universal design eliminates the need to stock multiple specialized inserts, reducing the quantity of tooling required while maintaining optimized wiping effects for various applications.

AI summary
A wiper insert and a tool with the same. The wiper insert includes a tool body, and the tool body includes a cutting part which is used to cut a workpiece. The cutting part includes a plurality of wipers. Adjacent wipers are connected by a transition surface, and the minor cutting edge angles of the plurality of wipers are set differently. With the technical solution of the present application, the problem in the prior art that the wiper inserts lose their wiping effects when they are mounted on different tool holders is solved effectively.
