The subject of this book is surface metrology, in particular two major aspects: surface texture and roundness. It has taken a long time for manufacturing engineers and designers to realise the usefulness of these features in quality of conformance and quality of design. Unfortunately this awareness has come at a time when engineers versed in the use and specification of surfaces are at a premium. Traditionally surface metrology usage has been dictated by engineers who have served long and demanding apprenticeships, usually in parallel with studies leading to technician-level qualifications. Such people understood the processes and the achievable accuracies of machine tools, thereby enabling them to match production capability with design requirements.

Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions , such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing. In geometric dimensioning and tolerancing , control of a cylinder can also include its fidelity to the longitudinal axis, yielding cylindricity. The analogue of roundness in three dimensions that is, for spheres is sphericity. Roundness is dominated by the shape's gross features rather than the definition of its edges and corners, or the surface roughness of a manufactured object. A smooth ellipse can have low roundness, if its eccentricity is large. Regular polygons increase their roundness with increasing numbers of sides, even though they are still sharp-edged.

И все тянул и тянул к ним свои пальцы. В Севилье Беккер лихорадочно обдумывал происходящее. Как они называют эти изотопы - U235 и U?. Он тяжко вздохнул: какое все это имеет значение.

 Не поддающийся взлому алгоритм? - Она выдержала паузу.  - Ах да… Я, кажется, что-то такое читала. - Не очень правдоподобное заявление. - Согласна, - сказала Сьюзан, удивившись, почему вдруг Хейл заговорил об.  - Я в это не верю. Всем известно, что невзламываемый алгоритм - математическая бессмыслица. Хейл улыбнулся: - Ну конечно… Принцип Бергофского.

Не. ГЛАВА 65 Бринкерхофф мерил шагами кабинет Мидж Милкен. - Никому не позволено действовать в обход фильтров. - Ошибаешься, - возразила.  - Я только что говорила с Джаббой. Он сказал, что в прошлом году сам установил переключатель.
