Praut CN-2D systtem was develped with to simpler tool machines programming, especially Oxgen cut, Laser, Plasma, Waterjet and Wood’s industry machines. The system is completely interactive and it helps you in all programming, it can be interfaced with commercial CAD with DXFDXF, NC1, CAM exit. The software allows breaking in of all geometric and technological informations necessary for the tool machine, until data generation for the CNC and their transfer. In every step corrections, controls and plotting of piece on printer is possible. Moreover, the programmer have not to know single tool machine paticolars.
