CADasCAM is a programme for drawing contours and creating CNC programmes for milling machines from these contours. The combination of design (CAD) and CNC programme (CAM) makes it possible to control CNC machines without specialist knowledge of CNC programming. The generation of the G-code in accordance with DIN 66025 can be customised to a large extent and should therefore be usable for common control systems. The control of the machine itself, e.g. control of stepper motors, is not possible with the programme. Separate software is required for this.
