Solution Overview
Problem
Existing wire electrical discharge machines lack the ability to predict component consumption accurately before machining, making it difficult to anticipate and manage wear and tear effectively.
Innovation Solution
A prediction device connected to wire electrical discharge machines that predicts the rate of component consumption based on machining conditions, using a prediction unit and display unit to provide operators with anticipated consumption rates and amounts, allowing for proactive maintenance and condition selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If component consumption is monitored after machining, then wear and tear can be tracked, but the ability to predict future consumption and plan maintenance is insufficient
Solution Approach 1:
The prediction device calculates and displays the predicted rate of component consumption before machining operations begin. By using the machining condition acquisition unit to obtain parameters and the prediction unit to compute consumption rates based on stored relationships, the system enables operators to plan maintenance activities in advance, avoiding unplanned interruptions and optimizing maintenance scheduling.
2Productivity
If machining conditions are optimized for productivity, then production efficiency increases, but component consumption rate increases
Solution Approach 1:
The prediction device provides feedback by displaying the predicted rate of component consumption corresponding to different machining conditions. This allows operators to see the trade-off between productivity and component consumption, enabling them to select optimal machining conditions that balance production efficiency with component longevity, thereby reducing unplanned maintenance interruptions.
3Reliability
If component replacement is performed frequently, then machine interruption risk is reduced, but operational time is lost
Solution Approach 1:
By displaying the predicted rate of component consumption before machining begins, the system enables operators to proactively plan component replacement timing. This preliminary information allows scheduling replacements during planned maintenance windows rather than performing emergency replacements during production, thereby maintaining machine reliability while minimizing operational time loss.
