Measurement & Machine Technology - Machine Tool Laser Alignment - Laser Calibration Specialists We are experienced on CNC Machine Tools, CNC Lathes, Horizontal Machining Centers, Vertical Machining Centers, Boring Mills, Manual Machine Tools, Coordinate Measuring Machines, Traveling Column Boring Mills, Long Bed Engine Lathes, Special Purpose Machines, and many more. A ballbar test or a laser system measuring the positioning accuracy on the diagonal, are ways of telling if your machine is in good condition, but that takes expensive equipment and specialty trained employees. Machine “earth” level is an important benchmark if you want to check yourself in the future without the need of a laser system. www.measurementandmachine.com   (546 words)

Efficiency of Feasible Weighted Least Squares Estimators of the Center and Radius of A Spherical Surface (ResearchIndex) Abstract: : A linear model based on the spherical coordinate system is employed for fitting a spherical surface to a data set obtained by a coordinate measuring machine (CMM). In practice, measurement data may have unequal accuracy on the different coordinate axes, thus a liner model with heteroscedastic variance of random errors is considered. A feasible weighted least squares estimate is proposed and its superority over the ordinary least square estimate is established. citeseer.ist.psu.edu /139862.html   (395 words)

Quality Magazine: Quality 101:Understanding Coordinate Metrology The coordinate system, invented by the French philosopher and mathematician René Descartes in the early 1600s, is employed in coordinate measuring machines (CMMs) to locate features relative to other features on workpieces. The Machine Coordinate System has three axes—X, Y and Z. When viewed from the front of the machine, the X axis runs from left to right, the Y axis runs from front to back, and the Z axis runs up and down, vertically perpendicular to the other two. The X, Y and Z axes of the Machine Coordinate System refer to the machine’s motions. www.qualitymag.com /CDA/ArticleInformation/features/BNP__Features__Item/0,6425,130525,00.html   (516 words)

Ball Bar (Dumbbell) Triple Cross The amazing ability of a Ball Bar (Dumbbell) to evaluate the overall performance of a Coordinate Measuring Machine is based on crossing or reversing the Ball Bar (Dumbbell). The result of using these simple reversal techniques with the Ball Bar (Dumbbell) set at two opposite angles is to evaluate the overall performance of the measuring machine in minutes. When an inclined Ball Bar (Dumbbell) is placed at a right angle to a machine axis is measured, the probe moves all the way down at one end and then all the way up at the other end. www.precisionballs.com /triple_cross.htm   (516 words)

Laser Metrology of the MMA antenna surface SMX Corp and Leica each manufacture a coordinate measuring machine (CMM) which should be capable of measuring the primary mirror surface of an ALMA telescope to an accuracy of better than 10 microns rms. Measuring the primary mirror at high elevation (say 60 and 120 degrees) requires a very stable measuring tower about 15 to 16 meters high; the low elevation measurement requires a stable tower of about 6 to 8 m height. The antenna performance tests of verifying good primary mirror stability with thermal and wind loading are very difficult to attack quantitatively, but the laser CMM method will probably be as effective as any. www.tuc.nrao.edu /~demerson/holopdr/lugten_laser.html   (676 words)

Symmetry vs. Position - Symmetry uses the same theory as Position, right? - Page 2 - The Elsmar Cove Forums To measure concentricity, I use a Coordinate Measuring Machine. Because of the difficulties involved in actually measuring concentricity error, I'm not sure where your data is coming from. As I also said earlier, it's been my experience that when concentricity is specified it's usually by someone who understands the everyday definition of the word (two things that are coaxial) but isn't aware that it isn't that simple in the GDandT sense. elsmar.com /Forums/showthread.php?p=100057   (1339 words)
