Excerpt from American Engineer and Railroad Journal, 1904, Vol. 78 In the ideal scheme of production, antiquated cutting tools, slow speeds and fine, hair-splitting feeds can have no part whatever. With machines in good condition, tools that will remove the maximum amount of material in a given time with the least frictional resistance and retain their cutting edge, form a necessary part of a perfect combination. The man who runs his machine, instead of letting his machine run him, will soon discover the proper shape of tool for a given (to be continued.) operation, and on all forgings that have been roughed out, the amount of feed and depth of cut will then be limited only by the pulling power of the belt. Railroad shop manufacturing. For every Operation there is a best form of tool, (not a half dozen different shapes, one as good as another), and as many of the operations in a repair shop are repeated every day, too much care cannot be exercised in determining that shape. Having adopted a series of standard sizes and shapes, tools should then be forged in dies to within 1-16 in. Of actual size and delivered to the grinding room. Whenever a machinist is kept waiting for a tool, the time so spent is lost beyond recovery, and to insure the maximum output of any shop, such waste of time must be eliminated. To accomplish this, a number of tools of various kinds must be kept ready for immediate use to supply all requirements.
