Abstract: An improved drilling machine and drilling method will allow rapid configuration and calibration. The drilling machine is small, mobile, and possesses extensive computing power to download positions of hole sites and to control the positioning of the end effector. The mini-driller conforms to various jig configurations regardless of the program model or position on the wing. In short, the controller for the mini-driller quickly orients the machine, downloads the hole sites appropriate to the model under construction and determines with accuracy the mini-driller's precise location in relation to the work piece. A graphic user interface allows the operator to read the projected position of the hole sites, as downloaded from the Numeric Control Server, off of the graphic user interface and to make ad hoc corrections to the projected hole sites.
