Abstract

In a machine tool, the tool is moved using a signal representing a required profile of the surface being machined. This signal is fed to a transducer, such as a piezoelectric crystal or a D.C. linear motor, which converts the signal into a corresponding linear movement which is transmitted to the tool. The tool can also be vibrated ultrasonically during machining. Such machines can be used for producing workpieces which are non-circular in cross-section and/or which are barrelled or tapered along their length.
