Radial inclination | Radiology Reference Article - Radiopaedia. org
Radial inclination or radial tilt is the slope of the distal radial articular surface in relation to the radial shaft in the coronal plane and is an important measurement in the evaluation of distal radius fractures and radial deformities Radial tilt should not be confused with volar tilt
In Situ Measurement of Spindle Radial and Tilt Error Motions by . . .
This paper presents a complementary multi-probe method for measurement of radial and tilt error motions of a spindle Neither indexing of artefact nor rotating of spindle housing is required and thus make it suitable for in situ evaluation of spindle performance effectively
Instrument Calibration Methods - Taylor Hobson
One high accuracy method of correcting the gain is by traversing the instrument stylus over a know step height and comparing the measured value against the step value to determine the correction factor, which can then be applied to all subsequent measurements
Precision Spindle Metrology
When seeking to improve a precision instrument, reliable spindle measure-ments provide insight needed to achieve higher performance in both manufacturing and metrology We begin with an introduction to the fundamental issues of spin-dles and spindle metrology
Measurement of spindle error motions by an improved multi . . . - Strath
Radial error motions at different Z locations are measured using the above method The trajectories of rotating centre are plotted in Cartesian coordinate in figure 7 (a) Linear fit is applied at each spindle rotary position to calculate spindle X and Y tilt errors The tilt error around Y axis is show in figure 7 (b)
Tilt, axial and radial error motion - Xeryon
Tilting is measured by measuring with 2 probes separated by a known Z-distance From the difference between both probes, we calculate the tilt angle The total radial error is a combination of radial translation and tilting of the axis We measure the radial error directly above the rotor surface
Spindle Error Movements and Their Measurement - Semantic Scholar
Method of calculating radial error motion Determination of the error radial motions is based on the radii of the circles determining the ideal and real motions of the rotating spindle At outset, for example, by the least squares method, a mean circle (LSC (Least Squares Circle) is defined that
Extabs SRI2012 Spindle metrology rev 5 - IOPscience
error motion is characterized by five components—two radial (RX and RY), one axial (Z), and two tilt (αX and αY) Two setups are required to obtain radial and tilt computed from a radial measurement at a low position and another at a high position (100 mm separation) For the low position radial
In Situ Measurement of Spindle Radial and Tilt Error Motions by . . .
Using this method, the radial error motions of the precision air bearing spindle were measured at seven axial positions and then the synchronized tilts error motions were calculated This demonstrated an efective approach for measuring four degree-of-freedom error motions in one setup with a small number of displacement sensor probes
Basic Wavefront Aberration Theory for Optical Metrology
To study optical metrology, the forms of aberrations that might be present need to be understood The purpose of this chapter is to give a brief introduction to aberrations in an optical system
