GF AgieCharmilles’ Form 20 and Form 30 sinker EDMs are equipped with the company’s AC Form human machine interface (HMI) said to shorten the learning curve for beginner EDM operators. The two models feature GF AgieCharmilles’ Intelligent Power Generator (IPG) and are said to reliably generate surface finishes of RA 0.1 micron and radii as small as 0.0007". The EDMs are designed for industries such as general mold and die, aerospace, automotive and communications technology.
The Form 20 features a 70-amp generator, while the Form 30 is equipped with a 140-amp generator; both are said to continuously optimize the EDM process and reduce electrode wear. Axis travels measure 13.78" × 9.84" × 9.85" (350 × 250 × 250 mm) on the Form 20 and 23.62" × 15.74" × 15.74" (600 × 400 × 400 mm) on the Form 30. The Form 20 includes a four-position integrated linear toolchanger, while the Form 30 is equipped with a six-position version.
The AC Form HMI control features a user-friendly organization and screen layout suitable for novice machine operators, the company says. Common measuring cycles such as Z-axis-level measuring and rotating workpieces around machine C axes are integrated into the interface. According to the company, manual adjustments and alignments to workpieces are unnecessary, which reduces non-burn times.

Among other benefits, these two shops have saved significant production time by using wire EDM for part-cutoff operations previously conducted on bandsaws.
