摘要： An involute external tooth profile (114) is cut into the periphery of a gear blank (96) by positioning a rotating milling cutter (64) with its cutting path perpendicular to the plane of action (92) of the desired base surface of revolution within the gear blank so as to penetrate the plane of action from the side thereof opposite to the base surface and with a predetermined line of intersection (118) which generates the involute profile (114) as the base surface rolls upon the plane of action. The rolling action causes the generating line to traverse the blank between its addendum surface and a depth sufficient to provide the desired length of active profile.

摘要： A machine tool assembly, and particularly a spindle unit therefor, is provided wherein the spindle unit is relatively small and is designed to run at rotary speeds of between 30,000 rpm's and 40,000 rpm's utilizing hydrodynamic bearings for the spindle shaft. The hydrodynamic bearings are effective to take increased loads versus similarly sized conventional metal-to-metal contacting bearings to provide a very stiff machining system even with the higher loads generated by the increased rotary operating speeds for high speed machining contemplated for the spindle unit herein. The bearings are also designed to use a water-based fluid which is compatible with the cutting fluid. Non-contacting fluid barrier seals limit and control the amount of bearing fluid leaked to the cutting fluid. Due to the compatible nature of the two fluids, small fluid leakage from the bearings will not hurt the cutting fluid. The cutting fluid circulated at an ambient inlet temperature, e.g. , 70°F., and leaves at a higher discharge temperature, e.g. , 120°F., to cool the spindle and bearings. A cutting tool mounting adapter is provided which is attached to the spindle shaft by expansion of the shaft socket with high pressure hydraulics for shrink fitting of the socket onto the adapter when the hydraulics are removed so that the traditional highly tapered sockets and tool supports are not necessary, keeping the size of the front of the spindle small. The adapter also allows a commercially available tool to be employed in the high speed spindle unit herein.

摘要： An integrated spindle and motor unit includes a housing containing both the spindle shaft and motor with hydrostatic bearings around the front and rear of the spindle shaft. The hydrostatic bearings utilize high pressure oil, preferably in the range of 1,200-1,500 psi and provide good load bearing capacity and increased stiffness for improved cutting accuracy when cutting within the full range of cutting speeds. The present spindle unit is designed to be run at high speeds. The front and rear hydrostatic bearing pads are closely axially spaced along the spindle shaft so that the dynamic stiffness of the spindle is increased to avoid resonant vibrations even at high speed operation thereof. The spindle unit incorporates a sealing system utilizing a series of non-contacting seals including a labyrinth seal and aerostatic floating ring seals which keeps bearing oil in the spindle. The aerostatic ring seals have air restrictor openings therein to create an aerostatic air film that also keeps the rings concentric with the spindle shaft even though the spindle shaft is tilted in a nutator. A permanent magnet (PM) motor is integrated with the spindle with the rotor of the motor on the spindle shaft carrying the permanent magnets rotating within the stator of the motor which is attached in the spindle housing. The PM motor herein can provide high levels of power, e.g., at least 100 hp at the tool head, even in the short span provided by the short spindle shaft. At high speeds the bearing fluid may be pumped by viscous pumping from the radial bearing pockets. To counter such viscous pumping, small low pressure pockets are provided with low pressure oil to fill the high pressure pockets with oil.

摘要： In a cutting machine having an octahedral framework (12), a cutting tool (14) is carried by a servostrut support (15) having a platform (16) mounted on extendable and retractable struts (18). In order to reduce deflections and to limit transfer of bending moments, from the servostrut support (39) to the other connected support sections (40) of the framework (12), the six struts (18) are mounted at pivot mounts such as ball joints (36) in a triangular support (39). Three of the pivotal mounts are positioned in a first triangle and in corners of the triangle support (39) and the other three struts are positioned in a second larger triangle in the triangular support (39). The nominal axis of rotation of spindle drive (27) for the cutting tool may be either about a nominal horizontal axis, a nominal vertical axis or a nominal 45° axis. Several frameworks may be arranged to define a hollow tunnel (80) with platforms projecting their cutting tools (14) from opposite sides of the transfer tunnel (80).

摘要翻译：一个集成的主轴和电机单元包括一个包含主轴和马达的外壳，主轴的前后均有静压轴承。静压轴承利用高压油，最好在1,200-1,500psi的范围内，并且提供良好的承载能力和增加的刚度，以便在全切割速度范围内切割时提高切割精度。本主轴单元设计为高速运行。前部和后部流体静压轴瓦沿着主轴轴向间隔开，使得主轴的动态刚度增加，以避免即使在其高速运转时的共振。主轴单元采用密封系统，利用一系列非接触式密封件，包括迷宫式密封件和静态浮动环形密封件，可将轴承油保留在主轴中。空气静压环形密封件在其中具有空气限流器开口以形成空气静压空气膜，即使主轴在章动器中倾斜，该空气静压空气膜也保持环与主轴轴同心。永磁（PM）电机与主轴结合在一起，主轴上的电机转子带有永磁体，电机的定子中装有永磁体，永磁体安装在主轴箱内。这里的PM电动机即使在由短主轴提供的短跨度内也可以提供高水平的功率，例如在工具头处至少100马力。在高速下，轴承流体可以通过从径向轴承腔的粘性泵送来泵送。为了抵制这种粘性泵送，为小型低压容器提供低压油以向高压容器内充满油。

摘要： A method and apparatus for machining a rotating workpiece to have a predetermined profile employs a linear motor (22) to reciprocate a cutting tool (16) toward and from the rotating surface of the workpiece (15). An armature (24) of the linear motor (22) is mounted on a pivoted toolholder (18), which is mounted in frictionless bearings, to reduce substantially the apparent moment of inertia of the combined toolholder (18) and armature (24) and the frictional forces to be overcome. The armature (24) is positioned relative to the tool (16) to provide a substantial mechanical advantage to increase the application force of the tool (16) against the workpiece (15). The stiffness is high as likewise are the work turning speed and the tool reciprocation speed, thereby reducing substantially the cutting time relatively to a conventional piston turning machine cutting time.
