Therefore, a cylinder with a diameter of 1mm can fit into a circular hole if it has a diameter of 1.1~1.4mm, that is, if there is a tolerance of 0.1~0.4 mm between the two objects. On the other hand, the tolerance cannot be applied at will but must be calculated accurately, as a tolerance that is too small will be insufficient to make the interlocking, while a tolerance that is too large will make the interlocking unstable, with the two objects passing through each other. … Read More
