A fixture is a mechanism used in manufacturing to hold a workpiece, position it correctly with respect to a machine tool, and support it during machining. Typically, fixture design involves the identification of clamp, locator, and support points, and the selection of corresponding fixture elements for their respective functions. The automation of fixture design activities in manufacturing is a...

Layered manufacturing (LM) or rapid prototyping is a process in which a part is produced using layer-by-layer addition of the material. In LM, slicing of the CAD model of a part to be produced is one of the important steps. Slicing of CAD model with a very small slice thickness leads to large build time. At the same time if large slice thickness is chosen, the surface Žnish is very bad due to s...

operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. in certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnec...

Positioning handles and occlusal locks have evolved as improvements to the Teeth-in-a-Day protocol. These improvements have enabled a more accurate alignment of the removable dental prosthesis during the conversion prosthesis technique. These improvements can be easily incorporated through computer-aided design and computer-aided manufacturing digital denture fabrication process.

STATEMENT OF PROBLEM Artificial teeth are bonded onto the recesses of a milled denture base in a complete denture prepared using computer-aided design/computer-aided manufacturing (CAD/CAM). Little is known, however, about the effects of basal shapes and offset values on the accuracy of positions of the bonded artificial teeth.

This clinical note introduces a method to assist surgeons in performing single-tooth dento-osseous osteotomy. For use in this method, a surgical guide was manufactured using computer-aided design/computer-aided manufacturing technology and was based on preoperative surgical simulation data. This method was highly conducive to successful single-tooth dento-osseous segmental osteotomy.

According to the working principle of spherical hob, computing formulae of normal and axial profile of the spherical hob are deduced, and calculation methods of other main parameters are introduced in the paper. Then the computer aided design and calculation of spherical hob is realized by Visual Basic programming language, which increases the calculation speed and accuracy. And the new manufac...
