The studious mechanic, ever on the alert for new and up-to-date information relating to the equipment, arrangement, organization, and management of the modern machine shop or manufacturing plant, must have noticed, and with some surprise, the lack of discussion in the technical publications on the subject of the tool room, as well as the stock and storerooms, that in so many shops are intimately connected with all shop routine. Such discussions as we have had heretofore have usually been on particular features, such as tool racks, tool trays, tool checks, steel racks, drawer racks, tool check systems, and so on, but in none of them have we been favored with a complete system for the management of the tool room and the stock room.
Again, we find many descriptions and illustrations of tools, jigs, and fixtures, always interesting and valuable, often indispensable for their particular sphere of usefulness in the shop, but seldom do we see plans or descriptions of how or where to keep them in the best condition and ready for use. It is no doubt true that in many shops these expensive accessories are often left on benches or under them, or on wall shelves in the rooms where they are used, subject to dirt, dust, rust, and the possibility of accidental injury.
We find many disconnected parts of systems for use in the stock or storeroom; how stock shall be ordered; how it shall be accounted for when it is received; how it shall be issued; how it shall be followed up to know what is on hand, what needed, etc., but never a complete system of management giving the details from the time stock is wanted until it is finally expended and accounted for.
It is proposed, in this article, to take up these matters in regular order, and to describe and illustrate, as fully as is here possible, the regular routine from the inception of a requirement until its final realization.
First to be considered is the tool room. This should be located apart from the general machine shop, as a too intimate connection does not seem desirable in practice, while it is self-evident that it should be convenient to the superintendent's office, drafting room, and pattern shop, and that it should be well lighted, comfortably warmed and ventilated. This room is properly divided into two sections, the first being the room where tools are made and kept in proper repair, and the second, the room where they are stored, repaired, issued to the machine shop as required, and received from the shop when no longer needed there.
The second section may consist of two parts, in one of which lathe and planer tools, milling cutters, drills, taps, reamers, files, jigs, fixtures, gages, and similar articles are kept, while the other part may contain the articles of stock and consumable supplies usually found in the ordinary stock room, such as machine, cap, and set screws, oil cups, metals, the smaller bar and sheet stock, bolts, rivets, nut blanks, oil, waste, emery, emery cloth, etc. It will be much more convenient in many ways to keep these two classes separate for storage purposes as well as for accounting and issuing.
It is assumed that the machinist portion of the tool department, or the tool-making room is equipped with modern machine tools sufficient in number, variety, and efficiency to turn out all the tools, jigs, fixtures, gages, etc., that may be needed. This equipment may consist of a 24 in. x 5 ft. planer, a universal milling machine, an index milling machine, a 10-in. shaper, a sensitive drill, a 25-in. upright drill, two 18 in. × 8 ft. tool room lathes, one each 24 in. × 10 ft., 20 in. × 10 ft., 16 in. × 6 ft., engine lathes, a 12 in. x 6 ft. speed lathe, a 6 in. × 18 in. surface grinder, a 4 in. × 30 in. grinder for cylindrical work, a disc grinder, three tool grinders, and two twist drill grinders. Also, the necessary large and small surface plates, straight edges, and similar tools and accessories that may be necessary for the production of good tool work.
It is also assumed that adjoining this room is the room wherein tools, jigs, gages, fixtures, files, etc., used in the shop are kept, and in connection with these, in the same room, or one opening from it, is kept such stock as machine, cap, and set screws, round, square, and hexagon tool and machine steel, brass, copper, and steel wire, sheet brass, copper, steel, and fiber, rough bolts, nut blanks, washers, and all similar articles of stock usually found in the machine shop storeroom, as well as belting, oil, waste, and similar consumable supplies.
