Planar Workpiece Tool Motion for Independent Multi-Axis Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools for processing planar workpieces, such as metal sheets, lack versatility in movement control, leading to limited processing options and increased process time due to synchronized and restricted movements of upper and lower tools.
Innovation Solution
A machine tool design that allows independent and simultaneous control of upper and lower tools' movements along multiple axes, enabling superposed traversing and stroke movements, which increases processing versatility and reduces process time by allowing flexible tool positioning and movement profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the upper tool and lower tool are moved synchronously along their positioning axes, then the machine structure is simplified and easier to control, but the processing versatility is reduced and process time increases
Solution Approach 1:
The machine tool divides the tool movement control into independent segments: the upper tool can be moved along its positioning axis independently from the lower tool's movement along its positioning axis. This segmentation allows each tool to follow different movement profiles, enabling versatile processing operations while maintaining a relatively simple overall machine structure.
Solution Approach 2:
The system transitions from static synchronous movement to dynamic independent movement control. The upper and lower tools can now move with different speeds, directions, and timing along their respective positioning axes, allowing adaptive adjustment of tool paths for various processing requirements without complicating the fundamental machine architecture.
2Device complexity
If the upper tool and lower tool are moved synchronously, then the control system is simpler, but the process time increases due to restricted movement options
Solution Approach 1:
The control system segments the movement commands for upper and lower tools, allowing independent trajectory planning and execution. This enables parallel processing where both tools can move simultaneously along their own optimized paths, reducing total process time while keeping the control architecture manageable through modular independent control modules.
Solution Approach 2:
The independent movement capability allows both upper and lower tools to perform useful actions continuously without waiting for synchronous coordination. Each tool can maintain its own continuous movement along the positioning axis, eliminating idle waiting time and maximizing productive action throughout the processing cycle.
3Manufacturing precision
If defined positioning of tool bodies is required relative to the stroke axis, then processing precision is maintained, but the adaptability for different processing operations is reduced
Solution Approach 1:
The system replaces static defined positioning with dynamic positioning control. The upper and lower tools can be positioned dynamically at any location along their positioning axes independently, allowing adaptation to different processing operations while maintaining precision through controlled movement. This dynamic approach enables the same tool configuration to perform multiple operations by simply changing movement parameters rather than physically repositioning or reconfiguring tools.

AI summary
A machine tool for machining planar workpieces includes an upper tool, a lower tool, a machine frame, and a controller. The upper tool is movable with a stroke movement along a stroke axis by a stroke drive device in a direction towards a workpiece and in the opposite direction and positionable with an upper traversing movement along an upper positioning axis by a motor drive assembly. The lower tool is aligned with the upper tool and is positionable with a lower traversing movement along a lower positioning axis by a motor drive assembly. The upper and lower tools are movable in a frame interior of the machine frame. The motor drive assemblies can be controlled by the controller. The upper and lower traversing movements can be controllable independently of each other. The upper tool can be controlled with the upper traversing movement and the stroke movement in a superposed manner.
