Description: 125 tungsten carbide die performs, 4-inches thick, were wire EDM.
Normal Performance: Of the first group of 15 performs to be wire EDM, eight performs cracked and had to be scrapped.
Performance After Meta-Lax Stress Relief: Meta-Lax stress relief was applied in batches of several performs at a time before wire EDM. The result was that Meta-Lax processing eliminated cracking throughout the rest of the program. A 50+ scrap rate was eliminated.
