Do you need Bespoke skilled engineering products?
Wicks Engineering Co. Ltd. has been established over 20 years, providing specialist precision engineering expertise.
However, we can equally well offer batch production facilities if you have a larger volume requirement, and would be happy to discuss your needs.
Precision Engineering is our speciality, precision engineers are are stock in trade, no job is too small or too big.
Professors Hiromu Nakazawa and Pat McKeown provide the following list of goals for precision engineering:
Create a highly precise movement.
Reduce the dispersion of the product's or part's function.
Eliminate fitting and promote assembly, especially automatic assembly.
Reduce the initial cost.
Reduce the running cost.
Extend the life span.
Enable the design safety factor to be lowered.
Improve interchangeability of components so that corresponding parts made by other factories or firms can be used in their place.
Improve quality control through higher machine accuracy capabilities and hence reduce scrap, rework, and conventional inspection.
Achieve a greater wear/fatigue life of components.
Make functions independent of one another.
Achieve greater miniaturization and packing densities.
Achieve further advances in technology and the underlying sciences."
Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time. These approaches have applications in machine tools, MEMS, NEMS, optoelectronics design, and many other fields
In the fields of science, engineering, industry, and statistics, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's actual (true) value. The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. Although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method.
A measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy. The result would be a consistent yet inaccurate string of results from the flawed experiment. Eliminating the systematic error improves accuracy but does not change precision.
A measurement system is considered valid if it is both accurate and precise. Related terms include bias (non-random or directed effects caused by a factor or factors unrelated to the independent variable) and error (random variability).
The terminology is also applied to indirect measurements—that is, values obtained by a computational procedure from observed data.
In addition to accuracy and precision, measurements may also have a measurement resolution, which is the smallest change in the underlying physical quantity that produces a response in the measurement.
