为了允许在制造过程中必然会发生的精度变化，并提供零件的互换性和正确功能，一个公差系统是必需的。
A system of tolerances is necessary to allow for the variations in accuracy that are bound to occur during manufacture, and still provide for interchangeability and correct function of the part.
具有互换性的零件的影响力。
但完全将具有互换性的零件引入美国——后来到全世界——的武器工业的并非靠了LeBlanc的努力，而是另一个人。
Despite LeBlanc's efforts, however, it would be left to another man to fully introduce interchangeable parts into the american-and later the international-weapons industry.
互换性：在铁姆肯的一个工厂里生产的轴承零件可以和全球范围内的其他工厂生产出来的零件相互替换。
INTERCHANGEABILITY: Bearing parts manufactured in one Timken Company plant are interchangeable with those made in every other plant throughout the world.
