Error Theory Application in the measurement (g): The million workers were measured with the aperture on the instrument as the point of comparison errors


For comparison choice. First, the pointing error produced by these two instruments pointing error of difference million workers were caused by targeting errors. Million workers were targeting method is the use of images, the processing aperture, the two end prone to falling edge, chamfer, etc.,[link widoczny dla zalogowanych], affecting the clarity of image contours, and pressure as measured by dotted lines outline the edges of the gun parts, one of the l0 a + ∞ corresponding aiming accuracy of a 20 ~ 3O Ⅱ pixel meter in diameter when measured on two-lane divided equally or by targeted methods aimed symmetry, corresponding aiming accuracy of this method is ± 5u ~ 1O mirror used as the point of instrument reflection principle, as shown in Figure 1 (0) as shown by the light emitted by the light condenser to illuminate a reticle on the reticle, the projection lens 0. Platinum mirror into the edge of the target object plane O, the point S, S and then by the imaging lens 2 in the division points on the board, this is just in the + '\If you move the table closer to the main optical axis of the workpiece surface, then some of the light reflected from the surface by 0 Imaging in s. 2 At this point in the reticle can be seen as the two cross lines s and s,[link widoczny dla zalogowanych], as shown in Figure 1 (bJ shows, if it continues to move the table so that the surface of the workpiece weight sets and the optical axis, as shown in Figure 2 ( d) shows, this time all the illumination beam reflected by the measured surface, and imaging reticle 2 in the groove between the two, that s move to dual-groove center and S re-sets, thus achieving double groove groove The set of units aimed at. Figure 2 (b) below, in the absence of target before the reticle 2 is equal to the distance between s and s 0 s and the objective lens magnification of the product. but I was depending on the surface of the distance from the axis twice, so it's high sensitivity, than the average doubling microscope. The value of up to 0.I ~ O.2gm,[link widoczny dla zalogowanych], when measuring the surface of the workpiece surface, the cross line into a curved shape like a vertical line. II Abbe error of length measurement requires the elimination of the basic principles of the Abbe error. the length measurement,[link widoczny dla zalogowanych], in order to ensure the accuracy of the measurement should be made part of the size of the tested lines and meter groove in the foot as the standard weight bench or in the extension cord on. In this way,[link widoczny dla zalogowanych], the remnants of Abbe error for the second error, its impact is very small, so negligible. quadric error is calculated as AAL: = where the distance between one or two microscope work ~ tilt angle. million workers in Australia and I was on the amount of pore size, whether it is in the horizontal axis or vertical axis units are inconsistent with the Abbe principle, it generates the error ,).()). ()) Z (on the next page 4 lens pressure ring, remove the mirror 8 (Fig. , loosen the two screws 2 cross slot, reducing the coil spring force. Orange to open the four top leek 3,4 (circle , unscrew the top 5, you can remove the seat and mirror frame. Loosen the top 7, seat and mirror frame can be separated. Unscrew the screws fixed coil spring, the coil spring can be removed. Refurbishment of the coil spring force is appropriate, shall be at the center of the coil spring is a bad error, the error is calculated as AL = s call-S where a DUT and the standard distance between the lines {- by rail linear error of leaving table Dayton oblique angle. As the point on the instrument in measuring aperture, the Phi measured with standard glass engraved aperture scale in the same straight line, the secondary error generated at this time, the impact is negligible. Third, the standard error of universal tool microscope apparatus there is no standard error of the glass reticle scale (system) correction device, the measurement results. Ruler with standard error of the glass groove. Instrument as the point in the aperture on the guillotine, the result does not contain the standard error of the glass reticle scale. Because it has an error correction device, the instrument panel has an error correction curve, the curve correction board to promote a parallel optical glass, so Huo line in the sub-scale of the eyepiece reticle deviate from the original position. The offset is determined by the curve board, while the curve groove board is based on the value scale of the test production to achieve the objective of the amendment above, the accuracy is only as points were higher than the million workers, the calculation of measurement error instrument like the point of the formula are: (o.s + l chu +) m, r, million workers were: ± (8 +. a m where a measurement of the length L (mm) 'H ... out of the standard ruler engraved line and side measuring the position of height (1171111) 304, the first laboratory measurement error discussion group feeds )(() x) x'x 'in the natural state, in two cross-slot screws 45' direction. For the mirror case and the framework of the hole on the top and the top finish of rust or low, to polishing and grinding. finish no less than △ 7, top is consistent with the top hole angle, the angle is greater than the top hole or the top 3. You can then wash your Mo pumping assembly. Xu had lost the top to the right tightness. When the swing angle mirror when not shake is flexible, and stable and reliable. a 4J a
