Not illustrated. 1913 Excerpt: ...should be noticed that with a fixture of this kind a machine may be run at its highest feed and cutting speed. The work is right down on the bed of the machine and the overhang of the knee and cutter is as short as it is possible to get it. Vertical milling in many cases presents several advantages over the horizontal style, as full use may be made of the reverse, traverse and crossfeeds without loosening that weak point in the miller--the knee joint. A fixture, or rather two fixtures, by which continuous milling is secured, are shown in Fig. 218. The piece having been clamped in position in the fixture A, the cutter commences to operate on it, starting from the position between the two fixtures. While this is taking place another piece is put in B. The cutter having passed over the piece in A, it is reversed, the feed changed to a higher table travel, and the cutter passes back over the same part, taking a light skimming cut due to the piece having been slightly sprung in the roughing operation. The feed is then dropped to its previous rate, and the roughing cut commences on the piece in B; meanwhile, the piece in A is changed. This method could be improved upon if the table were wide enough to take four fixtures, and the crossfeed utilized. The path of the cutter would then be in the form of a rectangle instead of a straight line and the finishing cut could, if desired, be dispensed with. Gang milling the forked joint X is accomplished in the fixture shown in Fig. 219. The clamping arrangement is duplicated on a circular base which can be located on the rotary table seen in Fig. 220. The central boss A serves as a register and the nut B projects 91 through the hole. This nut is tightly secured by a box spanner which is not shown. The diameter of the table...
