Geometric tolerances are specified using symbols on a drawing.

I had failed to take seriously her instinctive attempt, this last month, at spring cleaning, so inflexibly had I consigned her and our life together to the category of squalor. But the hormones of nest-building were in her as in every woman. A shaky sense of irredeemable guilt rotated in my stomach as I mentally reconstructed her face, her shining round brown eyes as vulnerable as bubbles of jelly a stray needle might prick, her Sphinxy mass of ringlets, her blunt moist muzzle of a nose. I tormented myself with remembering the silken rivers of dark body hair that loving inspection discovered everywhere on her limbs, and the girlish secrets between her legs, the semi-liquid pink split pod with its magical pea and the drier other aperture like a tight-lidded reptilian wink.

It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. This article is based on that standard, but other standards, such as those from the International Organization for Standardization ISO , may vary slightly. The Y The ISO standards, in comparison, typically only address a single topic at a time. There are separate standards that provide the details for each of the major symbols and topics below e. His work increased production of naval weapons by new contractors.

Geometric Dimensioning and Tolerancing has the unprecedented ability to cover almost every facet of tolerancing. It includes step-by-step procedures for dimensioning and tolerancing parts and assemblies. It shows how to analyze the tolerances applied using both worst case and statistical analysis. This book demonstrates the connection between the application of functional geometric tolerances and its effect on manufacturability and inspection, stressing optimal ways to achieve a high-quality product at the lowest possible cost to the customer.

ANSI Y Designer: tight tolerance is better i h l i b less vibration, less wear, less noise Machinist: large tolerances is better g easier to machine, faster to produce, easier to assemble. Tolerance Follows Function Assemblies: Parts will not fit together if their dimensions do not fall with in a certain range of values. I t h Interchangeable P t bl Parts: If a replacement part is used it must duplicate the original p within certain limits of deviation g part. Two Forms of Physical Tolerance Size Limits specifying the allowed variation in each dimension length, width, height, diameter, etc. Cost Sensitivity Cost generally increases with tighter tolerances Th There is generally a ceiling t thi relationship i ll ili to this l ti hi where larger tolerances do not affect cost e. Tolerances at the Limits of the Fabricators Capability cause an exponential increase in cost Parts with small tolerances often require special methods of manufacturing Parts with small tolerances often require greater inspection, and higher part-rejection rates.


The process of adding size information to a drawing is known as dimensioning the drawing. and tolerancing the shapes and locations of features on objects.

Dimensioning and Tolerancing Handbook The need to make more precise products, the requirements of mass production, and the desire for interchangeability have resulted in increased importance of clearly defining dimensions and tolerances.

 Тихо, - потребовал Фонтейн и повернулся к Сьюзан.  - Мисс Флетчер, вы проделали уже немалую часть пути. Постарайтесь пройти по нему до конца. Сьюзан вздохнула: - Программа принимает ключ только в цифровой форме.

Выключив паяльник, он отложил в сторону фонарик и некоторое время отдыхал, лежа под большим стационарным компьютером. Затекшая шея причиняла ему сильную боль. Такая работа была непростой, особенно для человека его комплекции.

Сьюзан понимала, что коммандер прав.

 Вы отлично знаете это. Это Цифровая крепость. - Вот как? - снисходительно произнес Стратмор холодным как лед голосом.  - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту. - Очень остроумно.

Они вступили в опасную зону: Хейл может быть где угодно. Вдали, за корпусом ТРАНСТЕКСТА, находилась их цель - Третий узел. Сьюзан молила Бога, чтобы Хейл по-прежнему был там, на полу, катаясь от боли, как побитая собака. Других слов для него у нее не. Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо. Если она потеряет с ним контакт, ей придется его позвать, и тогда Хейл может их услышать.

 На маршруте двадцать семь их отсоединяют.  - Панк снова сплюнул в проход.  - Чтоб мы не надоедали. - Значит, я не могу сойти. Парень захохотал. - Доедешь до конечной остановки, приятель.

Глаза Беккера расширились. - Ты его. Двухцветный равнодушно кивнул. - Где оно? - не отставал Беккер. - Понятия не имею.  - Парень хмыкнул.  - Меган все пыталась его кому-нибудь сплавить.
