Probing With EMC

Probing with EMC

For the purpose of this documnetation, probing shall be defined as a process of measuring items on on the table of a CNC machine equiped with a "probe switch" installed in the machine's tool holder. Under programed control, the machine “probes” the surface of an object by moving the probe switch towards the surface of the object until the the probe switch registers contact. At this point the machine immeadiately stops motion and the coordinates at the point of contact are recorded.

As a single operation this procedure may be used to check for flatness across a surface, measures clearances, etc... However, if this this proccess is repeated across many points of a model is it then possible to digitize the surface of the object.
