The concept of a hardware-in-the-loop experiment for high speed milling is introduced in this paper. The tool-workpiece interaction is virtually implemented in the experiment while the milling machine with the spindle is used as real element. In this paper, the basic components of the experiment are presented, namely, a contactless displacement sensor, a computational algorithm of the cutting force and a contactless electromagnetic actuator are discussed. Experiments on the prototype of the electromagnetic actuator are also shown to illustrate the potential of the concept. A feasibility study of the hardware-in-the-loop experiment is given, where the effect of the time delay included in the experiment is investigated.
