Planar Workpiece Machining Tool With Adjustable Cutting Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools for machining planar workpieces require multiple setup operations to accommodate different material thicknesses, leading to increased setup time and reduced productivity.
Innovation Solution
A tool system with an upper tool and a lower tool, where the lower tool features a group of counter tool bodies with varying cutting gap widths, allowing the same tool to machine different material thicknesses through adjustable traversing and rotary movements, reducing the need for frequent tool changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single-counter tool body design is used, then tool structure is simple, but multiple setup operations are required for different material thicknesses
Solution Approach 1:
The lower tool is segmented into multiple counter tool bodies (first counter tool body, second counter tool body, etc.), each with different cutting gap widths. This segmentation allows the tool to accommodate different material thicknesses by selecting the appropriate counter tool body, thereby improving adaptability without requiring complete tool replacement.
Solution Approach 2:
The lower tool is designed with multi-functionality by incorporating multiple counter tool bodies that can handle different material thicknesses. This universal design enables a single tool to perform multiple machining operations across various thickness ranges, eliminating the need for multiple specialized tools and reducing setup operations.
2Productivity
If multiple counter tool bodies are provided, then different material thicknesses can be machined with one tool, but tool body arrangement complexity increases
Solution Approach 1:
Multiple counter tool bodies are arranged in the transverse direction (perpendicular to the stroke direction) rather than stacking them in the stroke direction. This dimensional arrangement allows simultaneous access to multiple counter tool bodies and enables quick selection during machining operations, improving productivity while managing structural complexity.
Solution Approach 2:
A transverse movement mechanism acts as an intermediary to select and position the appropriate counter tool body relative to the upper tool. This intermediary mechanism facilitates smooth transitions between different counter tool bodies, reducing setup time and operations while managing the complexity of having multiple tool bodies.
3Adaptability or versatility
If cutting gap width is fixed, then tool design is straightforward, but adjustment for different material thicknesses requires tool changes
Solution Approach 1:
The tool system incorporates dynamic adjustability by allowing the lower tool to move in the transverse direction to select different counter tool bodies with varying cutting gap widths. This dynamic configuration enables the tool to adapt to different material thicknesses during operation, improving versatility while maintaining ease of operation through automated or manual transverse positioning.

AI summary
Tools for machining planar workpieces are provided that include an upper tool, an upper main body, and at least one tool body on the upper main body having a cutting edge. The tools further include a lower tool having a lower main body with a rest surface for the workpiece and a positioning axis oriented perpendicular to the rest surface, at least one counter tool body on the lower main body that has a counter cutting edge that is a closed contour. The cutting edge of the at least one tool body has a cutting contour that corresponds to the closed contour of the at least one counter tool body, and at least one group of at least two counter tool bodies on the lower tool can be associated with the closed contour of the least one tool body.
