A system and method for milling dental prostheses in a CNC milling includes affixing a lateral side of each of a plurality of ceramic millable dental blanks to a lateral wall of a fixture; securing the fixture to a chuck of the milling machine; wet milling a single dental prosthesis in each of the plurality of ceramic millable dental blanks with a diamond burred cutter; and removing the plurality of ceramic millable dental blanks from the fixture.

A 3D copy of a 3D subject is made by combining a 3D custom milled shape and a 2D printed 2D image sheet molded to the contours of the 3D custom milled shape. A 3D camera captures 3D details of the 3D subject and also captures a multi-color 2D image of the 3D subject. The 3D camera outputs a geometry file to a CNC milling machine that cuts a milling blank to make a custom milled shape. The 3D camera also outputs a 2D image file to a personal computer that prints the 2D image onto a plastic sheet. The custom milled shape is placed as a mold on a vacuum-forming machine. The plastic sheet is aligned to the custom milled shape and heat and vacuum pressure applied. The 2D image is molded into the 3D shape of the custom milled shape.

An apparatus and method for adapting a CNC milling machine for electroerosion machining. The apparatus includes a tubular electrode on the distal end of an adapter shaft. A tool holder on the proximal end of the adapter shaft is mountable in the chuck of a cutter spindle in the milling machine. The adapter shaft is rotatably mounted within a bearing and an electrical brush contact subassembly, both of which are supported by a bracket. The bracket is attached to the milling machine but insulates it from the tool electrode. The bearing supports the adapter shaft in alignment with the CNC spindle. An electrical power supply energizes the electrode and the workpiece for electroerosion in a gap between them. Electrolyte is circulated through the spinning tool electrode during operation. The CNC computer is configured to operate the machine, power supply, and electrolyte flow for electroerosion machining.

A method of building construction includes designing a building with software for execution on a computer such that an envelope of the building principally comprises expanded polystyrene foam panels, and the software is used to automatically generate a plan with reference numbers that identify substantially all the component pieces of the building. The software and computer are coupled to a computer aided design (CAD) program for generating computer numerical controlled (CNC) milling commands for expanded polystyrene foam panels, and a cut-list for steel reinforcing studs to fit into matching slots milled into the expanded polystyrene foam panels. At least the expanded polystyrene foam panels and matching steel reinforcing studs are marked with identifying numbers corresponding to the reference numbers. The expanded polystyrene foam panels are milled with a CNC machine and panel cutter according to CNC milling commands from the CAD program.
