ABSTRACT:
An apparatus (10) for generating a surface (S) on a workpiece (W) is proposed, which comprises a workpiece chuck (17) having a longitudinal axis (L), a spindle (18) for rotating a fly cutting tool (20) having a tool tip (48), and a moving device for moving the spindle generally transverse to the axis (L). The spindle further has a rotary encoder (42) for detecting an angle of tool rotation (γ), wherein the chuck is operatively connected with a fast workpiece servo (50) capable of moving it over short distances at high velocities. The servo is controllable taking into account the given angle of tool rotation so that the workpiece can be advanced toward and retracted from the tool in a defined manner while being cut by the tool tip. The limited geometry of the tool can thus be modified by moving the workpiece relative to the tool tip.
