AI Technical Summary
Technical Problem
In the existing technology, the operator needs to manually measure the density and roll diameter of the wire EDM machine to estimate the wire allowance, which results in a heavy operating burden and makes accurate measurement difficult.
Method used
By installing first and second rotational position detection sensors on the in-line electrical discharge machining (EDM) machine, the rotational positions of the winding drum and the feed roller are obtained. The ratio is used to calculate and estimate the wire allowance, reducing the need to measure the density and roll diameter.
Benefits of technology
It reduces the operator's workload, enables accurate estimation of line allowance, and reduces the possibility of processing interruption.
