Part-Probing Possibilities for EDM

摘要

Probing options for electrical discharge machining equipment range from simple to sophisticated. Here are options for wire, sinker and hole-drilling EDM. On-machine probing with a spindle-mounted touch-trigger probe is commonly used on CNC milling machines to speed and simplify setups. After an automatic probing routine identifies the location of several points on a fixtured part or workholding device to establish the part's exact location on a machine, the machine's CNC can automatically adjust the native work coordinate system to match it. This eliminates shimming, part nudging and other time-consuming duties that would otherwise be required to get the part leveled and aligned to perfectly match the machine's coordinate system.
