251 machines. Chapter Nine gives an overview of computer, machine tool and r o b o t interfacing techniques using standard interfaces and explains DNC {Direct Numerical Control) systems. Chapter Ten attempts to summarise simple project scheduling methods by giving examples of the CPM and PERT programs in the FMS Software Library. Dynamic scheduling methods are also explained. Generally applicable computer programs solving individual tasks during FMS design, evaluation and optimisation, are described in Chapter Eleven. Finally, Chapter Twelve introduces the most important social and human aspects of FMS, CAD/CAM and robotics, and gives advice on how to become an FMS engineer: this involves a combination of mechanical, production control, and software engineering. The text is accompanied by a number of software packages integrated in the FMS Software Library. Each program can run on most micro-, mini- and mainframe computers in the form of: a stand-alone turnkey package; a procedure library; and a UCSD Pascal UNIT. It may be ~¢orthwhile to note that the FMS Software Library is available for purchase from: Mentec International Limited, SUIC Building, University of Salford, Salford M5 4WT, U.K. The United Kingdom has probably a stronger claim than any other nation in terms of creation of the concept of FMS. The initial advantage of being the concept originator has, however, been lost through failure to apply it on any significant scale. It is therefore extremely satisfactory to see such a t e x t b o o k -- the first of its kind -- made available to the manufacturing community by one of the publishing houses of this country. IFS (Publications) Ltd. is to be highly c o m m e n d e d for undertaking its publication. (Their claim "World Leaders in Advanced Manufacturing Technology Information" in one of the brochures, is perhaps true in this context!) The b o o k is well produced and is strongly recommended by the reviewer to students, lecturers, designers, researchers, managers and practising engineers. It should be on the shelves of all libraries of universities, polytechnics, engineering institutions, research establishments and companies concerned with manufacturing technology and design. S.K.

Hot Rolling of Steel, by William L. Robert, Marcel Dekker, Inc., New York, 1983. ISBN 0-8247-1345-1, vi + 1033 pages, 800 illustrations, hard cover, SFr. 198. Professor Sansome, in his review of Cold Rolling of Steel (by the same author and publisher, 1978, see this journal, vol. 4, pp. 200--201), pointed out: " m o r e metal is deformed by rolling than by any other process, more research has been conducted into the rolling of metals than into any other

252 process and more papers have been published on the subject than on any other aspect of metal deformation, and yet surprisingly f e w books have been written about it ... Whatever the reasons that have deterred other engineers from writing a b o u t rolling, these have not impressed Roberts, who is to be congratulated for his self-imposed task so well." The reviewer o f the present b o o k can simply repeat the above passage for yet another superb piece of research reference by the author, the self-imposed task this time being on the h o t rolling of steel. The information presented in this vital companion volume to Cold Rolling of Steel was obtained from the vast literature in this field, from industrial sources and from laboratory-scale experimental programmes reported on by researchers and academics from both the research sector and educational establishments. The reviewer is able to identify four major subject categories into which the b o o k m a y be divided: (i) Principles of hot rolling inclusive of the history of h o t rolling and mathematical modelling o f the process; (ii) Hot rolling processes and practices -- this information covers such topics as rolling equipment, types of operations, reheat furnaces, roll pass design for various shapes and sizes of products, lubrication, specifications for typical hot-rolled shapes, etc; (iii) Hot-rolling steels -- these data treat the h o t rolling of both c o m m o n and special steels in terms of the influence of material properties on hot-rolling behaviour and the influence of hot-rolling procedure on t h e properties of the hot-rolled product; (iv) Follow-up treatments given to hot~olled products before their ultimate utilisation, and instrumentation and c o m p u t e r control involved in today's hot-rolling mills (which, in fact, govern the quality o f modern hot-rolled steel products). The reviewer is very pleased t o emphasise that in organising the material for this b o o k the major objective o f the author has clearly been to prepare a d o c u m e n t of m a x i m u m usefulness to engineers concerned with the design, production, post-treatment and use of hot-rolled steel products. The text is both comprehensive and effective, and is profusely illustrated with line diagrams and photographs. Marcel Dekker's production of this b o o k is of the usual high standard: this is particularly recommendable considering that the b o o k is o f over 1000 pages of a b o u t A4 size. It can be stated w i t h o u t any hesitation that the t w o volumes on rolling by Roberts will remain unique for years to come and that, as a major source of reference, they n o w stand alone in this field. Both the present and the earlier volume are strongly r e c o m m e n d e d to every library, rolling mill and steel-industry supplier, to advanced undergraduate and graduate students of metalworking, production technology, mechanical el~ineering and metallurgy, and to research workers, lecturers and practising rolling technologists.
