In the development of controlled anti-aircraft weapons of Germany during the Second world war, of course, surpassed all other countries. Work in this direction started there quite early and was based on a high level in the development of German science and technology. September 1, 1942, appeared the Memorandum of the inspector General, defenses of General von Axhelm, supported by Goering, who provided the following directions:
In today’s production is no surprise micron precision. Moreover, in the manufacture of many devices, mechanisms required to “catch” a few hundredths of a micron. That’s why in our days precision, or as it is called in the industry, precision manufacturing requires a skilled worker, so he could work on modern machines, able to produce products of the highest accuracy class.
Bomber Handley Page VICTOR. In January 1947 at a meeting Jen 163— secret of the governmental Committee the UK the decision was made to separate the development of the atomic bomb. It followed the refusal of the Americans to pass the English government materials in design and production of nuclear weapons. The plans of the Committee for the development of the first combat of the sample bomb was given five years, and by 1957 it was supposed to produce about 200 atomic bombs.
Cutting carbon – dioxide laser is the process by which materials are cut with focused, high-energy beam of light that is generated by a carbon dioxide laser. The laser beam is focused on a specific location of the material being cut and the heat generated forms a small, localized melting throughout the thickness of the material.
