Machine Tool Window Display for Synchronized Machining Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools struggle to effectively illustrate differences in machining methods to observers, as conventional methods rely on pre-recorded videos and projected images, making it difficult for viewers to understand actual operational differences.
Innovation Solution
A machine tool system that displays synchronized videos of actual and simulated machining operations on a large touch panel, allowing observers to visualize differences in real-time operations, including tool paths, swarf generation, and machining fluid flow, using cameras and a display control system connected to an NC device and personal computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pre-recorded videos and projected images are used to illustrate machining differences, then information can be displayed to observers, but observers cannot effectively understand the actual degree of difference in machining operations
Solution Approach 1:
The patent combines multiple information sources (pre-recorded comparison videos, real-time camera footage, and projected images) into a single integrated display system. The display device shows the pre-recorded video while the projection device overlays real-time machining images, allowing observers to simultaneously view both comparison and current operation without switching between separate displays, thereby effectively resolving the contradiction between information display and observer comprehension.
Solution Approach 2:
The projection device acts as an intermediary that bridges the gap between static pre-recorded videos and live machining operations. By projecting real-time images onto the display device or surrounding surfaces, the system creates a layered visual representation that mediates between historical comparison data and current operational states, enabling observers to intuitively grasp machining differences.
2Device complexity
If video reproduction is performed away from the machine tool, then equipment complexity is reduced, but the effectiveness of comparison demonstration decreases
Solution Approach 1:
The display device and projection device are designed to serve multiple functions: displaying pre-recorded comparison videos, projecting real-time machining images, and potentially serving as operational interfaces. This multi-functionality allows the system to maintain high demonstration effectiveness at the machine tool location without requiring separate dedicated equipment for each function, thereby resolving the contradiction between device complexity and demonstration effectiveness.
3Illumination intensity
If a large display device is attached near the window, then video visibility is improved, but the machine tool structure becomes more complex
Solution Approach 1:
The patent utilizes a projection device that can project images onto flexible surfaces or thin film screens positioned near the window. This approach provides large-area video display with high visibility while avoiding the structural complexity of mounting rigid large displays. The projection technology allows images to be displayed on adaptable surfaces that integrate with the existing machine tool structure without requiring substantial structural modifications.
