Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple amounts of wire radius compensation modification are summed up for different purposes, then the total compensation can be achieved, but the original individual amounts become indistinguishable and difficult to modify separately
Solution Approach 1:
The patent segments the wire radius compensation modification into multiple independent adjustable parameters (first modification amount, second modification amount, etc.), each corresponding to different purposes such as discharge gap adjustment and finishing allowance. This allows each parameter to be modified separately while maintaining their individual identities, resolving the contradiction between achieving total compensation precision and maintaining control simplicity.
2Adaptability or versatility
If finishing allowances are specified in the machining program at multiple points, then different finishing allowances can be applied to different portions, but modifying the program becomes burdensome and error-prone
Solution Approach 1:
The patent extracts the finishing allowance parameter from the machining program structure and makes it an independent adjustable parameter in the control system. This allows finishing allowances to be modified through the control device without altering the machining program itself, maintaining the ability to specify different allowances for different portions while eliminating the burden of program modification.
3Manufacturing precision
If the amount of wire radius compensation is modified to achieve intended finished size, then accurate machining results can be obtained, but the process requires modification of existing machining programs which is time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple wire radius compensation modification amounts in the control device before machining begins. These modification parameters are prepared in advance and can be selected and applied without modifying the machining program, thus achieving accurate finished sizes while eliminating the time-consuming program modification process.

AI summary
A wire electric discharge machining program is analyzed and a target shape for a workpiece is created. Multiple amounts of adjustment by which the amount of wire radius compensation for a wire electrode is adjusted are set. One or more desired ones are selected from the amounts of adjustment, and the amount of wire radius compensation is calculated by adding the selected amount(s) of adjustment to the amount of wire radius compensation. A machining route which is offset from the created target shape by the calculated amount of wire radius compensation is created.
