CNC device
As with all computers, the CNC device works on a binary principle using only two characters 1 and 0. Series of ones and zeros which is socalled machine language is the only language the computer understands. When creating the program, operators use a list of codes and keys to express the job information.
Drives transform pulse signals sent out from CNC device into motor signals, which tell the serve motor to rotate with each pulse. The rotation of the serve motor in turn rotates the lead screw which drives the linear axis. With each step of movement, the measure device sends a signal back to CNC device, which compares the current position of the drive axis with the programmed position.
