Abstract
Fast tool servos can be used in conjunction with diamond turning machines to produce precision contoured surfaces. This paper presents an overview of fast tool servo (FTS) technology and applications. A literature review groups the FTS devices by operating principle and performance. A new class of FTS is described in detail which uses a flux-steering actuator to achieve unprecedented performance levels. This Ultra-Fast Tool Servo (UFTS) has 30 μm stroke, 23 kHz closed-loop bandwidth, acceleration of 5000 m/sec2, and positioning noise of 2.1 nm RMS while cutting.
