大型模具制造商在原型和汽车行业使用电火花加工（EDM）显著缩短了试模、冲压和台架时间。它增加了模具的流动性，最大限度地减少了计划外维护和压线停机时间，同时增加了每个模具的生产时间。它允许100%的修剪边缘间隙进入试印机。这可以缩短交付周期，同时仍能以更低的成本保持卓越的质量。本文更详细地研究了这些结果，同时考察了大型电火花加工机床在这方面所起的作用。

THE USE OF ELECTRICAL DISCHARGE MACHINING (EDM) BY LARGE DIE MANUFACTURERS IN PROTOTYPE AND AUTOMOTIVE INDUSTRIES HAS SIGNIFICANTLY REDUCED TRYOUT, PRESS, AND BENCHING TIME. IT HAS INCREASED DIE FLOW, MINIMIZED UNPLANNED MAINTENANCE AND PRESS LINE DOWN TIME, WHILE AT THE SAME TIME INCREASING PRODUCTION TIME PER DIE. IT HAS ALLOWED 100% TRIM EDGE CLEARANCE GOING INTO THE TRYOUT PRESSES. THIS HAS THE EFFECT OF REDUCING LEAD TIMES WHILE STILL BEING ABLE TO MAINTAIN SUPERIOR QUALITY AT REDUCED COSTS. THIS PAPER LOOKS AT THESE RESULTS IN MORE DETAIL, WHILE EXAMINING THE ROLE THAT LARGE EDM MACHINES HAVE COME TO PLAY IN THIS.
