Christian Brecher,Manfred Wecknear, isentropic oscillations of isolated gaseous stars, and thus of compressible spherically symmetric equilibrium configurations, has largely been developed from the viewpoint of the hypothesis of the physical radial pulsations of stars. Written for doctoral students and researchers, this monograp

Feed Axes in Machine Tools,ment instructions in conjunction with tools. On purely mechanical and electrical/hydromechanical automatic production machines, information on the travel and speed required for machining a workpiece is available in the form of mechanical storage, or in cam plates or templates (refer to Chap. 8).

Design of Feed Drives,rate the required kinematic momentum directly by means of torque or linear motors (see Sect. 2.1). For indirect drive concepts, mechanical transmission elements (such as a ball screw spindle) are used to convert rotation to translation.
