STEP-NC Cncprocess Diag
STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise. The combined result has been standardized as ISO 10303-238 (also known as AP238). STEP-NC was designed to replace ISO 6983/RS274D G-codes with a modern, associative communications protocol that connects computer numerical controlled (CNC) process data to a product description of the part being machined. A STEP-NC program can use the full range of geometric constructs from the STEP standard to communicate device-independent toolpaths to the CNC. It can provide CAM operational descriptions and STEP CAD geometry to the CNC so workpieces, stock, fixtures and cutting tool shapes can be visualized and analyzed in the context of the toolpaths. STEP GD&T information can also be added to enable quality measurement on the control, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coordinate-measuring Machine
A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensor do exist. Depending on the machine, the probe position may be manually controlled by an operator or it may be computer controlled. CMMs typically specify a probe's position in terms of its displacement from a reference position in a three-dimensional Cartesian coordinate system (i.e., with XYZ axes). In addition to moving the probe along the X, Y, and Z axes, many machines also allow the probe angle to be controlled to allow measurement of surfaces that would otherwise be unreachable. Description The typical 3D "bridge" CMM allows probe movement along three axes, X, Y and Z, which are orthogonal to each other in a three-dimensional Cartesian coordinate system. Each axis has a sensor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynamometer
A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp. In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agency, dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). Beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behavior, and tribology.

Closed Loop Manufacturing
{{unreferenced, date=April 2014 Closed-loop manufacturing (abbreviated CLM) is a closed-loop process of manufacturing and measuring (checking) in the manufacturing machine. The pre-stage to this is inspection in manufacturing. The idea is to reduce costs and improve the quality and accuracy of the produced parts. General procedure Closed-loop manufacturing can be done in different ways dependent on the manufacturing technique and on the accuracy requirements. # Planning the sequence (iterations) # Producing nearly the target value on the part # Measuring the real value # Calculating the residual (stop if residual is smaller than needed accuracy) # Manufacturing the residual # Repeat from Step 3 Suitable manufacturing techniques CLM is very suitable for electrical discharge machining. Milling or turning is also suitable for CLM. Suitable measuring techniques In machining measurement techniques have to fulfill special needs. In particular optical techniques have the advantage ...

Advanced Technology Program
The NIST Advanced Technology Program (ATP, or NIST ATP) is a United States government (U.S. Department of Commerce, National Institute of Standards and Technology) program designed to stimulate early-stage advanced technology development that would otherwise not be funded. ATP is designed for early-stage research in industry, not academia, though it supported academia indirectly (as subcontractors or collaborators in projects). It was started under the administration of U.S. President George H. W. Bush in 1991 with special legislation enacted and implemented by the administration of President Bill Clinton in the Code of Federal Regulations Title 15, Volume 1, Parts 0 to 299. Starting in 1995, the Republican-led Congress, as well as the administration of President George W. Bush, repeatedly recommended its termination and the program was suspended in 2005 with the White House The White House is the official residence and workplace of the president of the Uni ...

Electrical Discharge Machining
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the or , while the other is called the workpiece-electrode, or . The process depends upon the tool and work piece not making physical contact. When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater, causing dielectric break down of the liquid, and produces an electric arc. As a result, material is removed from the electrodes. Once the current stops (or is stopped, depending on the type of generator), new liquid di ...

European Strategic Program On Research In Information Technology
European Strategic Programme on Research in Information Technology (ESPRIT) was a series of integrated programmes of information technology research and development projects and industrial technology transfer measures. It was a European Union initiative managed by the Directorate General for Industry (DG III) of the European Commission. Programmes Five ESPRIT programmes (ESPRIT 0 to ESPRIT 4) ran consecutively from 1983 to 1998. ESPRIT 4 was succeeded by the Information Society Technologies (IST) programme in 1999. Projects Some of the projects and products supported by ESPRIT were: * BBC Domesday Project, a partnership between Acorn Computers Ltd, Philips, Logica and the BBC with some funding from the European Commission's ESPRIT programme, to mark the 900th anniversary of the original Domesday Book, an 11th-century census of England.
