  • System and method for real time three-dimensional model display in machine tool
    Patent number: 6546127
    Abstract: A system for real time three-dimensional model display in a machine tool includes a plurality of motors each capable of providing relative movement between a tool and a workpiece along an associated one of multiple axes, a servo driver for controlling the motors, a numerical controller coupled to the servo driver for transmitting target three-dimensional coordinates of points stored in a memory to the servo driver such that the motors can be caused to move into the target coordinates of points and for receiving actual three-dimensional coordinates of points fed back from the motors, and an image processor for receiving the actual three-dimensional coordinates of points from the numerical controller and for directly transmitting the actual three-dimensional coordinates of points to a display screen, so as to achieve a real time workpiece shape display based on the actual three-dimensional coordinates of points of the motors.
