While WinNC is an exceptional training tool, it is not a total replacement for physical machining.

WinNC is often used in conjunction with CAD/CAM software. A student can generate a post-processed NC file from a CAM system (like SolidCAM, Mastercam, or Siemens NX), load it into WinNC, and verify that the output is correct before sending it to a physical machine.

At its core, WinNC is a software package developed by in close cooperation with Siemens . It emulates the user interface and functionality of various Siemens Sinumerik controllers—most notably the popular 840D and 810D systems.
