Abstract

A hardware-in-the-loop (HIL) experimental setup is presented to analyze the stability of turning process. In our test rig, the dummy workpiece in the spindle can be excited in radial direction by an electromagnetic contactless actuator. This actuator is utilized to emulate the contact (cutting) force that acts originally between the tool and workpiece in case of a real process. In the HIL test, the displacement of the dummy workpiece is measured with the help of an optical sensor. A high performance real target computer is used to calculate the theoretical cutting force based on the present and past values of the relative displacements of the dummy workpiece. For the sake of simplicity, linear cutting force characteristics is implemented together with the emulated surface regeneration effect. In the HIL test, the loss of linear stability is detected for various real spindle speeds and virtual depth of cut, namely, the theoretically predicted pattern of the instability lobes is verified.
