  • Publication number: 20220040780
    Abstract: A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely.

  • Publication number: 20190360568
    Abstract: An apparatus and methods are disclosed for retrofitting a manual benchtop milling machine utilizing servo controls and/or stepper motors. The present disclosure provides a retrofit kit for the modification of a milling machine by incorporating ball screws and ball nuts without removing or replacing the original acme nuts, which inherently have been properly configured and aligned to the machine on which they were originally installed. The retrofit kit of the present disclosure allows for the modification using the alignment of the original acme nuts in their proper location and alignment obviating the need for custom machining or alignment.
