Bibliography Introduction Few items that have come into service with the British Army have caused more controversy over their operating lives than that of the SA80 Small Arms for the s series of weapons.
Officially handed over on 2 Octoberproduction had reached overwhen it finished in L98A1 Cadet Rifle This case study looks at the background, development history, problems and controversies surrounding this assault rifle. Such problems and controversies have always generated interest in specialist publications, the general media and the political sphere, with the result that there was a lot of material available on the weapon and its history, in this case, much of it critical — "a weapon or weapon system is usually written about because of its innovative design, its impact on the field of battle, or even on world events.
This book is probably unique among all others on small arms because its subject, the SA80, is none of the above, and will be remembered for all the wrong reasons. The Soviets had fielded the Simonov AVS36 in but had failed to trial it properly with the result all sorts of problems in reliability occurred in the field.
Inthey also developed the 7. The British Army meanwhile, were still using the No. Experience during both world wars, and even the Korean War, questioned the need for infantry to have weapons chambered for full-power cartridges that are accurate out to as much as 2, yards.
A great deal of experimentation and testing took place, primarily of calibres between.

This round was tested with a number of bullets weighing between and grains 8. In line with this, and with an eye to the possibility of it being standardised within NATO, the original case rim diameter was enlarged slightly to more closely match that of the.
World War II had impacted on British small arms design in two ways. Practically all small arms were purchased abroad and as the Germans over-ran Europe, so a number of European gun designers managed to escape and come to England and join the Ministry. In the latter stages of the war, the Germans had suffered shortages of expensive alloys and so weapon designers had been forced to come up with equipment that used normal carbon steels wherever possible.
The Germans had eventually mastered the art of mass production during wartime that meant that they could produce items at a price far cheaper than most of the rest of the world was paying who were using the time-consuming, expensive method of extensively machined metal forgings but without any loss in quality.
Two different weapons influenced the post-war bullpup designs from ADE Enfield. The first was a sniper rifle, also designed at ADE Enfield, which was intended to be a solution to the problem of snipers being visually spotted when operating the bolt on the No. Three designs were produced but only one prototype was built, in 7.
It is interesting as it was even shorter than the Enfield designs under development, was completely sealed against the external environment and featured over-the-shoulder ejection, thus it was able to be fired either left or right-handed.
The first of the bullpup designs was the EM-1 or Korsac rifle, which originated with the Polish design team based at Cheshunt, Hertfordshire, headed by Roman Korsac until his retirement when Captain Januszewski who later changed his name to Stefan Kenneth Janson took over.
This weapon was mainly used to investigate the feasibility of the bullpup layout in this sort of weapon and owed its design to German weapons produced during World War II, most notably the FG42 paratroop rifle.
The design was such that the rifle used the same 7. This was done by moving the magazine up to the left-hand side of the receiver and onto the same vertical axis as the trigger and pistol grip, along with moving a hollow, recoil-cushioned butt forward so that it surrounded the rear of the receiver.
This design was moved to museum status on 25 September It was succeeded by a new design, from a team led by Stanley Thorpe that in fact ran in parallel with a second design from the team led by Stefan Janson. This new EM-1 was therefore also known as the Thorpe rifle.
The StG45 was intended to be even simpler than the StG44 and therefore easier and cheaper to manufacture 45 Reichsmarks compared to 70 Reichsmarks.
The first Thorpe rifle was proofed at Enfield on the 19 and 20 December to a pressure of 23 tons with a grain. Due to problems with the steel stampings making up the body of the rifle, the complexity of the design and the time needed to field strip it, the design was eventually dropped in light of the advanced state of the EM-2, also know as the Janson rifle.
This design employed the standard method of machining and finishing forged steel as used in the FG42 and Korsac rifle.cutting strategies for forging die manufacturing on cnc milling machines a thesis submitted to the graduate school of natural and applied sciences.
The introduction of Rapid Tooling (RT) technology has enabled prototype, pre-production and in some cases full production tooling to be fabricated within significantly reduced time frames. In the previous Chapter several proprietary solutions for direct tool production were described.
