Figure Data Mapping Between Drawing Screen and Workpiece Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining systems fail to establish a clear correspondence between positions on a drawing screen and the surface of a workpiece, making it difficult to accurately draw figures at desired positions or areas on the workpiece.
Innovation Solution
A figure data generation program that enables a computer to display a drawing screen, project visible light onto designated positions on a workpiece, and present corresponding positions on the screen, allowing users to understand and accurately position figures on the workpiece surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional machining systems are used without position correspondence display, then the system is simple and easy to operate, but it is impossible to understand correspondences between positions on a drawing screen and positions on a surface of a workpiece
Solution Approach 1:
The patent introduces an intermediary function that maps and displays correspondence between drawing screen positions and workpiece surface positions. This intermediary layer translates coordinates between the virtual drawing environment and the physical workpiece space, enabling users to understand position relationships without directly modifying the core machining system.
Solution Approach 2:
The patent creates a visual copy or representation of the workpiece surface position information on the drawing screen. By projecting or displaying position correspondence data as a visual overlay or reference layer, users can see the relationship between screen coordinates and actual surface positions, effectively copying spatial information across different domains.
2Manufacturing precision
If position correspondence display is implemented, then figure drawing accuracy on workpiece surface is improved, but the operation process becomes more complex
Solution Approach 1:
The patent performs preliminary establishment of position correspondence relationships before the actual figure drawing operation. By pre-calculating and displaying the mapping between screen positions and workpiece surface positions, users can plan and verify their figure designs in advance, ensuring accuracy before committing to the machining operation.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously displays position correspondence information during the figure design and machining process. This real-time feedback allows users to verify that their drawing operations on the screen will translate to the correct positions on the workpiece surface, enabling corrective adjustments if needed.

Data Source
AI summary
A non-transitory computer-readable medium includes a figure data generation program to cause a computer to execute a first process of displaying a drawing screen to make/edit an intended figure, a second process of commanding a processor to draw the intended figure on a surface of a workpiece to project a visible light onto a predetermined position on the surface, the processor including a visible-light source, the predetermined position having been designated by a user, and a third process of presenting a position corresponding to the predetermined position in the drawing screen.
