LM guide assembling method using half division and computer-readable record medium having program recorded for executing same

A method of assembling a linear motion (LM) guide by using half division, wherein the method is for assembling an LM guide in a base by using an LM rail in which a plurality of fastening holes is formed at an equivalent interval in a longitudinal direction, an auxiliary shelf in which a plurality of fastening holes is formed at an interval identical to the interval of the fastening holes in the LM rail, and LM blocks fastened to the auxiliary shelf and in which fastening holes are formed, the method comprising:

• disposing, at step S100, the LM rail on the base;
• fastening, at step S110, among the plurality of fastening holes formed in the LM rail, a first hole and a (2.sup.n+1)-th hole from one end of the LM rail by using a fastening means;
• installing, at step S120, an angle measuring device on the auxiliary shelf;
• fastening, at step S130, among the plurality of fastening holes formed in the LM rail, a (2.sup.n−1+1)-th hole from one end of the LM rail by using a fastening means;
• respectively disposing, at step S140, the LM blocks on the first hole and the (2.sup. n−1+1)-th hole from one end of the LM rail;
• disposing, at step S150, the auxiliary shelf on the LM blocks respectively disposed on the first hole and the (2n-1+1)-th hole from one end of the LM rail, the auxiliary shelf being formed integrally, and fastening the auxiliary shelf by using a fastening means;
• setting, at step S160, an angle of the auxiliary shelf to a zero angle in the angle measuring device;
• moving, at step S170, the two LM blocks on which the auxiliary shelf is coupled to be disposed on a (2n-1+1)-th hole and a (2n+1)-th hole from one end of the LM rail, respectively, and measuring an angle of the auxiliary shelf;
• calculating, at step S180, a predetermined straightness correction amount according to the angel of the auxiliary shelf obtained in the step S170;
• and
• loosening, at step 5190, a fastening means of the (2.sup.n−1+1)-th hole from one end of the LM rail and moving a position of the (2n-1+1)-th hole of the LM rail by the straightness correction amount obtained in the step S180, and fastening the hole by using the fastening means, wherein, the steps S130 to S190 are repeated while reducing n by one until n becomes n=1, wherein n is a natural number.
