From the developer:
TurnMaster Pro for Windows controls a 2-axis lathe type machine and provides graphical simulation of part programs. The CNC part program can be typed directly into the editor screen, or can be generated via a CAD/CAM program. The interactive mode allows you to see the operation performed graphically as you type each CNC line, aiding in part program development or training.
