UCK-type low temperature control device
= M) + ? (m) · m (4) the system of compensation for the error model of the software - the above (2), (3J, (4) type. Must be given a claim for a computer store and pick up the parameter type. This means that a limited factor must be the mathematical expression to describe the various functions. the expression is as follows: limonene! two! limonene,[link widoczny dla zalogowanych]! a (*) Ⅲ-I a (*) mj (6): a + e-j: ;: ce a + a (7) measuring distance (:, m),[link widoczny dla zalogowanych], (ln. Ⅲ. I), (-z ~ ar) is converted to a standard distance (~ 1, +1) (i 1 +1),[link widoczny dla zalogowanych], (a】, +1). Now The 8 Jing motion function can be made for a 39 - to become a series of Legendre polynomials Legendre polynomials depending on the number of used items: 1. measuring machine model, It is the type of error that is only valid projects. usually 2-4 -. t2. measuring the number of times. If To estimate the parameters of models and ec the matrix of the network of measurement points. III 1 measurement and interpretation of results; measuring machine that measures the Italian Institute shaving Colonnefti (IMGC) for the implementation of this task, using a SIP560M type coordinate measuring machine. The following parts of a kinematic chain : '(1) a move in the axial direction: [for Taiwan (2) a movement in the column axis; (3) a 2-axis direction in the installation of the extension units in the column; (4) an installation end of the extension units can be divided into degrees of rotation on the spindle probe. by moving the table column and carriage were measured. the movement of each axis is perpendicular to each other. contact with the workpiece probe gives a signal,[link widoczny dla zalogowanych], recorded three coordinates scale position to the workpiece touch probe moves all the predetermined point,[link widoczny dla zalogowanych], until all the surface to be measured and recorded at various points in the readings measuring machine measuring machine has the following parameters: sensor steel grating, optical reading were; * measuring range = 410 × 26Ox31Omm {· resolution = 01li1T_; · accuracy (determined by the manufacturer); axis G = (O.6 + L / ∞) m space M = (O94-L185o) m111111 · probe: parallel to the sensor displacement Multi-directional pieces; no internal friction: the linear mass confusion instrumental Jiang; put a 40 at an angle bracket I: measurement resolution = 1n. 2. IMGC volume measurement process with 6 l made a new model sphere 'to prove the correctness of error compensation. twitch from the pre-set number of counting, measuring 17 sphere model. sphere diameter of about 17.46Film. mounted in a hanging column of the stick. to the shaft by Steps to fix a flat amount surrounded by all bleeding, rods can be easily along the * axis perpendicular to the move. and the vertical axis CMM line. axis mounted on a ball in the 6. plane (parallel or inclined to work measuring machine Taiwan plane) relative to the shaft axis and different angles to create the conditions set model. template structure to ensure that touch many of these points on the sphere. Qu made of steel, rods and columns with the measuring machine table with the same material made. template can be moved, moving can be easily removed without removal of dust and grease. the requirements of the measurement process is as follows: (1) to determine the system error light measuring machines (2) close and reduce the random error. such as the repeatability of CMM return error and stability; ( the measurement process to avoid the temperature measurement process is as follows: (1) sphere of the reference point (in a different direction to take 1O points) in the amount of circumference l split to eliminate the transient relationship with the measurement such as electrical components of the drift measuring machine, (2) constant contact force is 0.075N and the steady rate; (3) the center of which the average of the coordinates and the center distance between the ball and the ball calculation of the average; (4) to close and reduce the random error of repeated measurements. Calculation of the center distance between the ball and the ball point and the coordinates of the average of three measurements (5) measuring the temperature of a model meal _ the temperature measuring machine components. to to avoid one of the most troublesome factors reduce the quality of the measurement. measuring machines around the air temperature should be asked ∞ ± 0.2 ℃. to Italy; velocity and acceleration do not affect the measurement of such precision measuring machines, because contact measurement points When measuring machine downtime, and then move very slowly, each lO0 ~ m pause until full contact probe that point .3. test results
