Wire EDM Path Drawing Visualizing Core Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machining technologies for wire electric discharge machines lack the ability to effectively check the operation and sufficiency of the core fixation function during machining, leading to potential core detachment and significant productivity losses due to undetected errors in the core fixation settings.
Innovation Solution
A machining path drawing apparatus that utilizes a numerical controller or personal computer to simulate the machining process, allowing the core fixation function to be visually checked by distinguishing its operation through different display attributes such as color, type, and thickness within the machining path, enabling workers to evaluate the core's fixation status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional machining path drawing is used, then the machining path can be displayed, but the core fixation function operation cannot be visually checked
Solution Approach 1:
The display system segments the machining path into different visual representations: normal machining paths are shown with one display attribute, while core fixation function operating portions are shown with different display attributes (color, type, or thickness). This segmentation allows workers to visually distinguish and check the core fixation function operation without complicating the overall display system.
Solution Approach 2:
The patent applies color changes as a display attribute to indicate when the core fixation function is operating. By changing the color of the machining path portion where core fixation occurs, workers can easily visually check the operation and sufficiency of the core fixation function during the machining process.
2Reliability
If core fixation function is operated during machining, then core can be fixed to workpiece, but workers cannot evaluate whether core is sufficiently fixed
Solution Approach 1:
The system provides visual feedback by displaying the core fixation function operating portions with distinct display attributes. Workers can evaluate whether the core is sufficiently fixed by checking the displayed information about where and how long the core fixation function operated, enabling easy assessment of fixation reliability.
Solution Approach 2:
The evaluation of core fixation is moved from a physical dimension (direct observation of core attachment) to a visual information dimension. By adding the dimension of visual display with different attributes, workers can assess core fixation sufficiency through the displayed machining path information rather than physical inspection.
3Loss of information
If machining program is referenced to check core fixation, then operation instructions can be seen, but relative position and center of gravity considerations cannot be evaluated
Solution Approach 1:
The patent merges the machining program information with the visual machining path display. The core fixation function operating portions are superimposed on the machining path visualization, combining program instruction data with spatial and temporal context. This allows workers to evaluate relative position and center of gravity considerations directly on the visual display without separate program analysis.
