What is the performance of your machine tools? It is better to catch errors before they appear in parts bymeasuring both the volumetric positioning accuracy andthe dynamic contouring accuracy. Volumetric positioning accuracy Using the laser vector technique (patent pending), 3displacement errors, 6 straightness errors and 3 squarenesserrors can be determined in a few hours while conventional laser interferometers may takes a few days. Dynamic contouring accuracy Using the laser/ballbar (patent pending),contouringaccuracy of various radii at high feed rates can be determined. Furthermore,...

A laser/ballbar is designed for the non-contact circular contouringmeasurement (Patent pending). The hardware used for the test are anMCV-500 laser calibration system, an optical adapter, and a flat-mirrortarget with an adjustable mount, a PC interface card, and a notebookPC with Windows  software. For a small radius or high feed ratecircular test, high data rate is required. With a special PCMCIAinterface card, a data rate up to 1000 data/sec can be achieved. The software for the data collection and data processing is a Windows basedsoftware. With a few clicks, the data can be collected...

The laser/ballbar uses a laser Doppler displacement meter for themeasurement. Hence the accuracy is very high, typically 1 ppm andtraceable to NIST. The telescoping ballbar uses a transducer for themeasurement. Hence the accuracy is low, need periodical calibrationand it is sensitive to temperature changes.Of course, two sets of measurements with two setups are needed for thelaser/ballbar to generate the circular path as compare to telescopingballbar, only one setup and one set of measurement is needed. A performance comparison is shown below. > The major features are: the measurement is...

This is an add-on package to the MCV-500 laser calibrationsystem for the measurement of squareness and straightness.The package includes a quad-detector and an optical square.The quad-detector is a precision position sensor, and theoptical square is a precision penta-prism to bend the laserbeam 90 degree. A laser produces an intense beam of redlight which is a straight line of the greatest accuracy in a vacuum. In atmosphere, the straightness of a laser beammay be changed by temperature gradients or air currents.For a typical indoor condition, the stability of the laser beamis in the order...
