Differential indexing error detection tube
The total error of the measurement method for the t'd wake + + li + assistance should normally be the d ≤ (1 / 3 ~ 1 / 10) T,[link widoczny dla zalogowanych], if you choose d ≤ / 10, then ≤ / 1O0 a breaking off of a sweet wine ~ ( 1) shown in Figure 2, the differential cylinder at the radius of the groove; r2 its positioning in the hole with a radius of the mandrel radius, units are IIm. In order to analyze conveniently,[link widoczny dla zalogowanych], the first set differential coaxial tube inside and outside the network. Beware of the hole axis and the tangent, the maximum eccentricity. Resulting error is also greatest. 0 A cylindrical rotary center for spindle turning center spindle through the thimble is connected with the optical dividing head and with the synchronous rotation, e is eccentricity, that is, e =. A cylindrical tube for the differential line dividing cut out one end point, AOB = a scale value for the differential cylinder, amidships. One is the sound show the value of the optical dividing head,[link widoczny dla zalogowanych], because AOB a 0.40 +. 40B, the / OAO B-B shows a stern, = Qu scale value for the differential cylinder dividing head with optical indication of the difference, in units of rad. In △ AO0, the. By the Sine with: AO / sm # = 0D/sin the R / gm = sinAa, is a sin △ e Lu. McLaughlin has the formula m: g_m △ d-Aa-A/3l + △ / 5I + ... due to small, △ a high-order terms can be neglected. Then Aa = eBin / (rad) = l0800n () (2) can be seen that the eccentric spindle A hole generated by errors cyclical. When = 2,[link widoczny dla zalogowanych],32 (O ≤ ≤ 2) when, △ ‰ a 10800e/aR (), that is, for the largest assembly error d. Combined with equation (1) e ≤ aPd4/l08oO (3) actually. Differential between the cylinder bore concentricity and cylindrical (mm), the cylindrical mandrel with the additional eccentricity is 0 ≤ e ≤ / 2, the largest cylindrical mandrel with eccentricity up to e: a r + @ t / 2, into (3) may} rl ≥ + / 2 a mad '/ 10800 (4) by (4) calculate the measurement accuracy to meet the minimum radius of the mandrel size. Sub, machine,[link widoczny dla zalogowanych], 2I measurement technology in early 1994. № I (I section, rare anti-cow, the actual volume of the differential cylinder 11 parts R and r2 are the existence of certain tolerance. Let R and tolerance were persons with L, who L2 <mm), in order to ensure measurement accuracy, R should be removed limits R-L], then by (3) calculate the maximum e value. When e a E / 2 ≥ 2 island, calculate the minimum value should be taken on the limit n +. . When a state e 2 <2 Island when the tolerance zone should rz Xiang into Ⅱ [2 Island / (e a / 2)] a district l, r values were calculated in order to take + L: m + ISLAND ( 【e a / 2), ..., + island one by one I) ・ (e a / 2), will receive a tolerance zone that corresponds to a measurement of the heart to ask the -1 value if the radius of the axis cylinder of the axial length of the small differential can only design a slightly taper spindle, as long as the differential engraved cylinder dividing line of the cross section perpendicular to the axis of the size of the circle satisfy (4) can be. . M word by computer analysis Diagonal accuracy. Huang Wei-Yuan Yan first (Nanjing industry 'were chu 10016) Electric Institute', such as flat plate under mortar summary error Diagonal m word often used to test the accuracy of its more complicated calculation. This article describes the generation of Meng manual analysis by computer calculation method is simple and correct. First, the meter base conversion between word Diagonal take this Example from Figure 5 × 5, measured approach by top to bottom, left to right as shown in Figure sagittal O, B, s,, U, V, said survey line overlap point, said point conversion after the assessment of the value of the base surface of the line angle values from the original Australian units of measure conversion line for the prospective point value, the sequence order shown by the series line, each line the value of measuring point line conversion relationship is as follows: c / ll \ '_ prince Yu 11. Second diagonal I - 1_ ① line: = A1 + A good first point where the line that the value taken as the mold, do not write hit a little later each survey line conversion to take the endpoint method, and this line of two end points are assessed based form surface part, so the end point of the line of zero values, said measuring point where the serial number, from 1 to that number of rows or columns to save the online test that measured the number of rings, one by one 1. Said one of She River Link ① line value, 1. Should be calculated on; a 2. In order to write a brief on the type to read as follows, and other similar writing style is taken. A: Σ merge duplicate entries have a Σ11; ugly one Σa - Σ, (1) 1, by (1) to determine the line ① value of five-point line. ② line: Once a day + yu 6 6 (2) line in B said two end points ② contour value. Obtained by the following formula Bin. - Fat-F {a One of a {+. Σ / 2 +1 cs, direction and measured the accumulation line in the opposite direction, type (3) ② line 6, calculated with a ring ring taken to be negative compared to the situation above activities are to take the following negative-type (g) the code written as follows;
