Abstract

1,138,342. Copy-milling. A. SCHMERMUND. 12 Oct., 1966 [22 Oct., 1965], No. 44724/65. Headings B3B and B3K. In a machine tool in which a curve is to be machined on a rotating workpiece 231 a primary cam 201 and follower 213 are provided which control the movements of the tool head 284 of the machine, and in order to produce modified curves means are provided which include a secondary cam 211 rotating in dependence upon rotation of the workpiece, a secondary cam follower 209 which regulates the movements of the primary cam, and a control member 290 adjustably mounted so as to vary the ratio between the movement of the primary cam follower 213 and the movement of the member 290. The primary cam 201 is mounted on an hydraulic cylinder 202, movement of which is controlled by a valve 207. In one embodiment as shown, the linkage from the auxiliary follower controlling the valve 207 is partly hydraulic (valve 248 and cylinder unit 250) and partly mechanical (gears 259 ... 263 and shaft 208). In an alternative embodiment (Fig. 1, not shown), the corresponding linkage is purely mechanical. A further control valve 222 is actuated by a pivotally mounted lever 214 carrying the primary follower and regulates the hydraulically effectuated movements of the tool head 284, the valve 222 being adjustably mounted by means of slides 287, 289. An hydraulically released brake 280 supports the tool head on the post 229 in the event of fall of hydraulic pressure. The work-holder 235 can be adjusted laterally on a slide 234 and is driven together with the cam 211 by a flange mounted electric motor. The milling tool is driven by an electric motor 285. The tool spindle is housed in a tubular member (308, Fig. 4, not shown) adapted to be fed forwards by a rack (309) and pinion (310) and hand wheel (312), to position the tool.
