The first NC machine was first invented in the 40s and 50s, by modifying the ordinary machine tools. In this case ordinary machine tools added to the motor that will move the controller to follow the points are inserted into the system by recording paper. Machine combination of servo motor and mechanical system is immediately replaced with analog and then digital computers, creating modern tooling machines called CNC (computer numerical control) that were later have revolutionized the design process.
In general, how to operate a CNC machine by entering the numeric tail command buttons are available on the instrument panel on each machine. Each type of CNC machine has its own characteristics in accordance with the factory that makes the machine. But characteristically there are 2 ways an absolute system is a starting point cut as a reference and is valid during the process. And the system incremental in this system the starting point placement which is used as a reference is always on the move in accordance with the actual point of the last stated.
CNC machine tools equipped with cutting tools that can make precise work piece and can perform numerically directed interpolation (based on numbers). CNC operating system parameters can be changed through software programs (software load program) is appropriate. The precision CNC machine is more accurate to thousandth millimeter accuracy, because the uses of ball screw on each axis of transportation.
In CNC machining usually use 3 axis for movement of X, Y, Z, but for generally 2 axis lathe X and Y. for a new lathe to rotate the turret now using servo motors do not like that used by the system hydraulic. You can see in the new TAKISAWA lathe, while the lathe is still using hydraulic Moriseiki. To use hydraulic way turret sensor number setting tool somewhat difficult because of using 2 switches phase A and phase B, which can be read more than 4 tool. For the turret servo motor is relatively easy to use, just specify the tool 1 (first).
