Subsequently the Department. The hole under the bus to reflect its axis benchmark. Pole to copy the table by adding a fixed vertical slider or the machine spindle,[link widoczny dla zalogowanych], respectively, moving x, y to the table, copy the table with a hole under the bus measured values of the two ports up and down regulating micro-jin hard to make it equal, that parallel to the axis of a B and the table. 3.2 Adjust the level of the three axes of the two axes of the plane on the bus reflect its own axis, respectively, moving x, Y table and the table were measured with the copy on the bus two axis values, adjust the trim v-type iron to be equal. Repeating 3. I, it is still with the table parallel to the c axis parallel to the table. 3.3B-B Y axis parallel to the hole side of the bus adjusted to reflect its axis B-B, move the x,[link widoczny dla zalogowanych], Y table and copy the table with a side of the bus were measured two-port limits to the value of X, so fine-tune the micro-jack Well makes the x coordinate value to the same limit, then the B-B and the Y axis parallel to. Check the above two steps, and ultimately makes the part is consistent with measurement requirements. 3.4 to read the angle measurement values measured copy sheets in the axis B-B near the upper side of the bus Inoue to determine the next move on the side of the bus, read on the side of the bus on the coordinates of the point (x, y ) wells will copy the table to zero. Appropriate mobile x-Y table copy sheets in the tested wells makes the axis B-B on the upper side of the bus and the indication is zero, again read the coordinates (X, y2). Were the amount of angle: port = Arctg (y2 A y 【) / (x2 a xt) 3.5 to determine a position. . . . . . . . . . . i. . . . c. . . . . . . . . . . . . . . . . . . . . . Children with a total technology _ La surgery 200O ・ №. 5 is a virtual point of a measuring point that we can attain the mother used drugs and the zero point and drug driving a straight line perpendicular to the table to reflect any point. Copy table will be placed on the bus on the point of the axis d,[link widoczny dla zalogowanych], and the proper _ compressed read out the zero point coordinates. Move x to the table, copy the table to make contacts with the workpiece side of the plane and the indication is zero,[link widoczny dla zalogowanych], read x, as shown in Figure 2 shows. Y = (X,) sin mouth cosa (d is known), mobile x, Y to the table, you can be a point of tellurium; 3.6 to read the measured values of linear dimensions of copy sheets in a spot pattern due compressed zero, then read the coordinates x, mobile workstations, copy the table so that the probe against the b points, copy the table and make it move up and down the probe hole on the right bus at the location x to the fine-tuning table, making a point value and copy that shows the same value. Then read the coordinates x to the Xb, you can get: L2: XbXa, then the L tracks dating back micrometer diameter D; is:, _l = L2 a Dl / 2 method for the integrated error is: jI_ Yong cut = ± 0.2Y, A, I, 1. 5.
