1. Concept of adjustment

In precision mechanics, the setting is the way in which two parts of a single machine engage each other in a way such that a shaft fits into a hole.
The coupling is related to tolerance in the sizes of both parts. If one has much greater that the other does not fit a size. Because of that ISO standards were developed to standardize measures, allowing interchangeability of parts and series production. The tolerance for an axis value is identified with a lowercase letter, while holes capital letters are used.
The machining tolerance is designated by who designed the machine taking into account some parameters as function and cost. The smaller the tolerance the greater the cost of machining.
Parts involved setting are referred to as male and female. Male parts are those that have the extensions whose external face will adjust on the inside of the female part. For example, axes, trees of transmission, cotters, grooves, etc. Female parts fit in reverse to the male, such as holes, slots, etc. Also keep a close relationship of adjusting threaded elements, gears, matrices, the distances between the centres of holes that have boxes of speeds and reducing or other mechanisms.
To produce parts in series, it is necessary to verify have the right quality to produce components at the end of the process must not be excluded since they do not fit to assemble the machines. Therefore the companies implemented quality control departments which perform measurements and checks of the parts to ensure that the quality is the proper or stop production in case of errors in the process. Before starting series production machine tools receives adequate according to the machining operation to run calibration. Then performed the first piece receives a rigorous control of all parameters of quality involved. If the result is positive, the quality control of the process passes to be performed by the operator of the machine, to which must have the instruments of measurement, gauges and gauges that are necessary.
In order to verify the accuracy of the parts are used measuring instruments such as calipers and Vernier, micrometers, gauges, watches comparators, gauges of buffer (pasa-no pass) to verify holes and Horseshoe gauges (go pasa-no) to check external diameters.
The buffer size has two machined ends of different length. The longest is the passes. Cylinder passes dimensions correspond to the actual minimum size of the nominal dimension, and the short cylinder corresponds to the side does not pass and has the dimension corresponding to the diameter greater than the corresponding nominal dimension. For his part in the Horseshoe to verify outside diameters openings are related inversely with the previous caliber.

2. Meaning of adjustment

The word setting has a Latin origin: comes from "ad" = a, and "justum" = right, coming to mean just place or arrange one thing to another, to adapt it to their performance, in the event of a mechanical part; or so they conform each other, so we talk about adjusting a screw or adjusting engine. Also can be adjusted such ideas, to match those of other people and reach an agreement, or offences with penalties, graduated according to the severity of these, or revenues with expenses, so that the latter will not exceed the first.
Conform to required to satisfy demand optioned properly. Conform to the law means to comply with it. Reckoning, in the accounting sense of the seat that can be made so that the accounts reflect their real value is called. But also is named (settling of scores) of reprisals people make privately as retaliation for acts committed against them, which is illegal at present, although they were admitted in early historical times.
Price adjustment means to accommodate them to the real economy, for example in case of inflation or deflation.
Currency adjustment means to adapt the value of foreign currency to local, for example when a devaluation.
A structural economic adjustment is a program that apply States to mitigate its deficit by reducing public spending, lowering, or not increasing wages to State, not doing public works, etc., and increasing taxes.

3. What is adjustment

The term setting, generally and in most of the contexts in which it can be applied always refers to the same thing, the union, adaptation or accommodation of one thing on another who is closely linked to the first and in this way allows the correct operation, either of a mechanical part which is located in the engine of the car, allowing that you start, either already in a completely different context, such as the table of dialogue between a Trade Union which represents the interests of a particular group of workers with the Government, the agreement in favour of an adjustment, for example, involves and serves to discuss the agreement reached and the end point to discrepancies that were in issue between them.
Adjustment, then, is a widely studied and relationship needed to be present in precision mechanics, since as we anticipate above, the coupling between two key pieces that belong to a team or industrial machine will depend on the life of this.
Mechanical to be adjustment will need an axis on the one hand and one hole on the other, that match, course, as a condition sine qua non, for this will bring to fruition the coupling between the two parts. Meanwhile, conversely, any of these exceeds the extent, both pieces not can in no way be adjusted, but to prevent that from happening this last situation is that there are ISO standards that control and set the tolerances in this regard. By extension, these same guidelines focus towards other areas of technology, as it is the case with the computer. Thus, not only is fundamental adjustment when we consider the mechanisms involved with the proper placement of a circuit, a chip or a peripheral on a computer, but also when trying to harmonize the implementation of a programme for a given operating system. In this way, "set" environments that allow a classical program of operating system Windows running on a computer that works with Linux, among other situations.
In another, the concept of adjustment is also portable to the biological sciences. Physiological adjustments are part of the reality of millions of living beings, in particular in the context of the changing environmental conditions (climate, humidity, the number of predators...). A slightly more specific, human medicine indicates an adjustment when intends to modify drug therapy. In these cases, the adjustment is often called degree; so, when the dosage of a product is inadequate, indicated the adjustment to the route of administration, the recommended daily amount or frequency of use of that particular drug.
On the other hand, the word fit, also occupies a prominent place in economic issues, although in this context, their application, even if it has that effect or purpose, has a generally negative connotation, since it is used to refer to the economic policy that many Governments have implemented, and which has resulted in the contraction of the salaries and wages of public workers to reduce the fiscal deficitthe fearsome "cuckoo" from most of the world's economies, by the way. The adjustment processes often mark the history citizen of a nation, especially when the consequences reach to raise unemployment rates, credit interest rates and other indicators that cause a detrimental impact on the population.
As we can see, setting is part of the most different processes (everyday and not so much) of the lives of the people, so their knowledge is integrated into the tools with which we have to improve many parameters of our reality.
