ABSTRACT:
Upper and lower work-pieces are fitted with each other to obtain a product. The work-pieces are provided with separate pairs of lands 11, 12, 13 and 14 to be fitted with each other. A land of the least rigidity is initially selected, and a fitting operation is carried out for the first land at a portion of an assembling allowance. Then, a self-guided fitting of the remaining portion of the first land is carried out. Then, a provisional fitting condition is created by disengaging the first land except at the least rigid portion. Then, the correction of the deviation in the second land is done by obtaining a relative displacement between the upper and lower work-pieces while the engagement of the first land is maintained. Then, the fitting of the second land is carried out.
