Design and implementation of a rotary fast tool servo for a turning machine
… of a rotary fast tool servo (RFTS) in a machine tool for turning ophthalmic lenses. To machine nonrotationally symmetric lenses, the cutting tool on the RFTS must move synchronously with the spindle rotation. Therefore, to cut a lens at high spindle speeds, the cutting tool must be …

High bandwidth rotary fast tool servos and a hybrid rotary/linear electromagnetic actuator
… auxiliary servo axis that is added to a diamond turning machine (ultra-precision lathe) to allow generating free-form non-axisymmetric or textured surfaces on a workpiece. A rotary fast tool servo produces an in-and-out motion of the tool relative to a workpiece by swinging the tool along an arc …

Reliability of torque and temperature feedback for an autonomous glass monitoring system
… use of the system is for a glassblowing-pipe turning machine designed to keep a blown glass object centered about its axis of rotation and to keep the object heated within a set temperature range. Temperature data was collected with a handheld IR thermometer for static and rotating samples …

Design and control of a long stroke fast tool servo
… The FTS is mounted to a T-base diamond turning machine (DTM). The FTS is attached to a hydrostatic bearing supported in-feed stage which is driven by a second linear motor. The in-feed stage is allowed to move in response to the FTS actuation forces and thus acts as an integral balance …

CSADP, a classical control system analysis and design package
… loop compensator for a precision diamond turning machine. Open loop frequency response data gathered from the machine was used as the basis for compensator design using Bode methods. The required compensator coefficients generated by the program were programmed into the servo for testing. …

Design and development of thin optical components for nonimaging applications = Diseño y desarrollo de componentes ópticos delgados para aplicaciones anidólicas
… relevant lately with the development of molding machines, for example 5-axis diamond turning machine. Although some components are very complicated for shaping, the manufacturing costs are relatively insensitive to the complexity of the mold especially in the case of mass production (such as …
