Any deviation in the form is expressed as increased cylindricity. Cylindricity is applied to …
WebCylindricity essentially controls the outside "shape" and "form" of the part similarly to how Rule 1 does, except that it is used to FURTHER REFINE that tolerance. Say, for example, you had a pin with a rather large tolerance on its diameter. You might be willing to accept the pin at any size, but you need it to be relatively straight and round.
