The CNC controller is the central processing unit that interprets G-code programs and coordinates the motion of machine axes and auxiliary functions, such as spindle speed, tool changes, and coolant flow, to produce machined parts.
Typical interfaces include Ethernet, USB, RS-232, and RS-485, which are used for networking, data transfer, and connecting peripheral devices. These are referenced in IEC 61158.
It uses a closed-loop system with feedback devices like encoders that provide real-time position data to the controller, allowing it to correct any deviations and maintain the specified positioning accuracy and repeatability.
Typically, it operates in ambient temperatures of 0 to 55°C, with relative humidity of 10 to 90% non-condensing. It also has protection ratings of IP54 to IP65, depending on the model. Always check the manufacturer's specifications.
