Its higher speed and numerous improved mechanical features also permit more effective control over quality and uniformity output. Temperature control, for example, made automatic the hot strip enters the finishing electric temperature and sounds warning there any variation.

PAUL Last year the Westinghouse Co. spent approximately $5,- 000,000 new machine tools and manufacturing equipment, this year has already spent about $2,000,- 000. The primary reason for buying new tools the part any progres- sive manufacturing industry is, course, give its customers high- quality products competitive prices. Other reasons are the creation new products, redesign existing prod- ucts, shortening the work week, and increased labor rates. The product engineer continually redesigning his product, whether motor, automobile, refrigerator what not, for the purpose increas- ing its efficiency, reducing cost, building into sales appeal. the re- design, one the major requirements build better product for the same money equivalent product for less money. Naturally, the equip- ment and tool engineer called into the picture make his contribution meet these requirements. The automotive industry and the re- frigerator industry, for example, re- quire new tooling programs every year, not only for the purpose re- ducing the cost the product but pri- marily because the From address Mr. Weaver tion Forum, sponsored the Westinghouse company. WEAVER Director, Equipment, Inspection and Test, Westinghouse Electric Mfg. Co. brought out new design which has certain features that make features cannot produced the same equipment economically. Hence the necessity for new machine tools. True, order justify this added in- vestment, there must savings. These savings are principally due the de- sign the product and not the in- stallation the new machine tool. Electrical engineers may redesign motors, changing some part that in- stead its being made turret lathe, can produced more eco- nomically multiple-spindle screw machine. That naturally obsoletes the turret lathe and requires the purchase multiple-spindle screw machine. Many examples this kind could given because the design engineer continually improving his product make more efficient and increase sales. The purchase equipment produce may only incidental. When improvements are considered, important note contributing factor those prod- ucts that are the influencing factor other products, for instance mea- suring equipment. Today, unskilled operator can measure higher de- gree accuracy than was possible years ago the most skilled mechanic. The fact that possible higher degree accuracy again makes necessary the installation im- proved equipment that can meet these greater accuracies. Recently, the writer saw practical shop measuring device that would measure millionth inch. The machine tool manufac- turers will have develop machine tools capable producing such accu- racies. Again, will mean replace- ment present equipment with equip- ment that superior anything heing produced now. The writer currently has doubts whether anyone can give accu- rate definition “surface quality.” other words, “how smooth smooth Before standard can established, method measuring needed.

Production and Purchasing Power Many events during the last seven eight years will have great influ- ence replacing old machine tools and the necessity for new equipment. There must definite relation be- tween purchasing power the indi- vidual and costs product. the purchasing power 1929 were com- pared with that today, would un- doubtedly found that the dollar went great deal further 1929. Ap- parently, this relation purchasing power cost has been definitely dis- turbed that today the standard living has been reduced. The contrib- uting factors this reduced standard living might be, for instance, the shorter work week, which has been es- tablished hr. instead hr. With the same equipment, workman cannot produce much work hr. did previously 48; there- fore, there less per employee. Also, during this same time, wages have been increased. This also addéd the cost, well all these added taxes frequently the news. All these things have contributed the unbalance production and purchasing power. There only one way bring them back the same this relationship, and that in- creasing human efficiency. Human ef- ficiency can increased manufacturing equipment. Therefore, far the manufacturing industry concerned, maybe all these sup- posed mistakes that the nation has made during the last five six years might prove great advantage. ACHINE tools are meeting the special needs in- dustry; for example, gears are being cut air conditioned rooms for increased accuracy, shown here. the past, during periods low ac- tivity, the search has been for new product that would pull the country out the depression. This time, might the correcting these scrambled basic conditions that estab- lish the country’s standard living. Less Skilled Labor The machine tool and the tool engi- neer have been gradually transferring the skill the mechanic from the man the machine. many opera- tions today requiring the highest ac- curacy, unskilled semi-skilled labor with adequate equipment has been able meet the demand. For this reason, during the last years, there has been certain amount curtailment the training skilled help. business improves and crease the shops, there will again shortage skilled help. New machine tools and manufacturing equipment will have developed reduce the need for great skill. Such trends are definitely here, and will continue grow. Progressive in- dustries have recognized them and taken steps meet the demands. ve ° ° ° descriptive Point” Deephard Steel registered trade-mark any steel regardless SAE analysis, man- ufactured and processed Foote Brothers Gear Machine Corp. means special process impart high surface hardness, great depth hardness, and gradual fusion this hardness with the core area.

Automobile Industry buggy whip business not what used be. Blame the automobile for that. The automobile and the hundreds time saving machines and devices that are used making have put reach the average pocketbook. Back 1890, the birth the automobile, there were about teamsters, draymen, coachmen and hackmen mounted the rear end horses. Now there are only about them. But that not all it. There were some 39,000 harness makers 1900; now, there are but 7500 them. There were 30,000 coach and wagon makers 1900. Now, there are only 4000. Blacksmiths have shrunk during this time from 215,000 Wheelwrights from 13,000 none. That means, nearly can figure it, that the automobile has abol- ished some 150,000 jobs, since 1900. the other hand, has created during that time some six million new jobs, according the calculations the Automobile Manufacturer's Associ- ation. For remember, addition the half million motorcar makers and the three million truck drivers and chauffeurs and the labor repair shops, garages, filling stations, traffic signal shops, accessory shops, etc., the auto- mobile has generated per cent the employment the gasoline industry, per cent the rubber industry, per cent the plate glass, per cent the alloy steel industry and down the line. Who says machines not manufacture employment? Before the automobile, there were about one Now reliably estimated that fully six million million people who earned their living because people have employment that directly caused some form highway transportation, excluding the automobile.
