Abstract

Mr Rissik needs little introduction to engineers, least of all to readers of Aircraft Engineering, since much that is contained in his latest book on Quality Control was foreshadowed in articles published in this Journal during the war years.

Abstract

IN this issue is brought to a conclusion the series of three articles on “ Quality Control in Production Engineering ” by MR. H. RISSIK who is one of the pioneers of the use of statistical charts for controlling the quality of products during manufacture. He is a member of the B.S.I. Committee on Statistical Methods in Standardization and Specifications, and was, we believe, responsible for the first experiment in the application of quality control to production engineering in England—at the Croydon works of MESSRS. CREED & CO.—in 1940. In addition to this, he has been occupied during the last six months or so in giving special lecture courses on the subject at Technical Colleges in various parts of the country.

Abstract

THE statistical method of controlling product quality during manufacture—a technique commonly known by the shorter title, Quality Control—is a very recent development in the field of production engineering. In point of fact the first application of this technique to machine‐shop production in this country took place late in 1940 at the Croydon works of Messrs. Creed & Co. Ltd., a firm whose name is a household word in electrical communications, for the Creed teleprinter is known all over the world. At the same time it must not be thought that quality control as such, or the use of the so‐called quality control chart as an aid to manufacture, is a purely wartime development. Statistical methods have been employed in British industry, notably in electric lamp manufacture, and in the production of both cotton and woollen textiles, for more than fifteen years, whilst the technique of quality control itself was originated by Dr. W. A. Shewhart of the Bell Telephone Laboratories, New York, in 1922. But where engineering practice was concerned, the application of statistical methods did not present itself until quite recently as a necessary or even convenient solution of manufacturing difficulties.

Abstract

THE first part of this article, published in last month's issue of AIRCRAFT ENGINEERING, outlined the operation of the non‐statistical method of sampling inspection commonly met with in purchasing specifications, and explained the inability of such a sampling clause to discriminate effectively between good and bad quality product. The present issue describes the practical applications of statistically designed sampling inspection procedures, giving adequate quality assurance wherever 100 per cent inspection of the product is either inapplicable or uneconomic.

Abstract

A FREQUENTLY recurring problem, more particularly in the sphere of electrical engineering practice, is the determination of the equivalent rating of a machine or piece of apparatus under conditions of intermittent loading. By equivalent rating is to be understood the value of the continuous load, whether expressed in terms of current or power, which will produce the same final temperature rise as is actually produced by the given intermittent load.

Abstract

THE first part of this article, published in last month's issue of AIRCRAFT ENGINEERING, laid stress on the importance of the technique of quality control to modern production engineering processes, and discussed the basic principles of this technique. The present issue describes the practical applications of quality control and the use of control charts.

Abstract

JUST over a year ago the Institutions of Civil, Mechanical and Electrical Engineers held a joint meeting in London to discuss “The Application of Statistical Control to the Quality of Materials and Manufactured Products”. That conference, attended by the Ministry of Supply and some eight hundred members representative of the engineering industry and the Services, both Armed and Civil, is destined to become a landmark in the world of British engineering practice, and for two very good reasons: First, because the conference officially sponsored the idea that the science of statistics has a place in the field of engineering production; and, second, because the conference officially recognized the fact that product quality is every whit as important as manufacturing output, that is to say, product quantity.

Abstract

WE publish this month an interesting article by MR. T. H. DAY ingeniously drawing attention to a striking analogy between the system of forces acting on an airscrew and on a direct‐acting engine. The diagrams he has prepared certainly produce strong evidence in proof of this similarity; to which, so far as we are aware, attention has not previously been called. There are, of course, comparable cases, such as those between certain electrical phenomena and mechanical forces, and there are no doubt others. It strikes us as being an interesting exercise to try and discover some of these; which might have beneficial effects in leading, in some instances, to simplification.

Abstract

The second part of this article, published in last month's issue of AIRCRAFT ENGINEERING, described some of the practical applications of the quality control method to machine shop production and, in particular, the use of control charts based on measurement. The present issue deals with a method of quality control based on the use of limit gauges, and with the applications of the control chart for “number defective” appropriate to this method. A further article, to be published in a subsequent issue, will discuss the extension, of the quality control idea to the sampling inspection of components and similar products in bulk, as an economic alternative to the detail (100 per cent) inspection which hitherto has been customary in such cases.

Abstract

WHILE the introduction of statistical methods into the analysis of aeronautical experimental data, whether for quality control in production, for the interpretation of the results of structural and aerodynamic laboratory experiments, or for airline operation, has been brought about only in recent years, it may by now be fair to assert that their advantages and even their indispensability are no longer in dispute. Hitherto, investigations on these lines have usually involved, explicitly or implicitly, only the ‘normal curve of error’ and allied considerations; owing, it may be thought, to the controllability of the various manufacturing or laboratory techniques, but also perhaps to the scarcity of data hitherto available. It may well be, however, that with the accumulation of information arising out of investigations planned with particular reference to the statistical analysis of their results the whole range of the apparatus for statistical analysis, usually confined to such fields as those of biology or economics, will be called into full play.
