Software Extends Digital Readout Use to EDM Machines

The Acu-Rite brand of Heidenhain Corp. (Schaumburg, IL) introduces new software for its 300 Series digital readout (DRO) that allows users to control a sinker EDM machine as well as grinding, milling, and turning machines.

When the new EDM software is loaded into a DRO300 and coupled with an IOB 610 interface box, it enables the simple control of sinker EDM through the use of three relay signals. Included on all new multipurpose DRO300s, the software’s key EDM control features are:

• Automatic depth programming. Machine’s ram can be configured to automatically retract or dwell at the target depth.
• Dwell cycle. The relay holds the Z depth until spark-out occurs or can control an orbiter cycle.
• Reverse fault detection. This prevents creep-out of the bath during a burn cycle.
• EDM display mode. This shows current ram depth, maximum depth reached, and target depth simultaneously on the three-axis displays.

For those who already own an Acu-Rite DRO300, v1.3.1 can be downloaded for free on the Software Updates page of www.acu-rite.com.
