CNC Cutting Machine Practice Test 2025 – Complete Exam Preparation

In the context of CNC machines, DAC stands for Digital Analogue Converter. This device is crucial in the operation of CNC systems because it converts digital signals generated by the machine's controllers into analog signals that can drive motors or other components. CNC machines rely heavily on precision and accuracy, and the DAC plays a vital role in achieving this by ensuring that the digital instructions from the computer are accurately translated into mechanical movements.

The proper functioning of a DAC ensures that the CNC machine performs the required tasks with precision, such as cutting or engraving materials, by providing smooth and accurate control of the motors. This enables the machine to interpret complex programming commands effectively. Understanding this aspect of CNC machines is essential for anyone involved in their operation or programming, as it underlines the importance of signal conversion in achieving desired machining outcomes.
