Abstract

Current techniques used to analyze the dynamic characteristics of a machine tool are time consuming and require a high level of technical expertise. To determine the stable depth of cut for a given spindle speed, the frequency response function (FRF) of the tool/spindle system must be measured. The FRF is determined by measuring the displacement caused by a force applied to the tool through a broad frequency range. Some previous work has been done to automate the measurement of FRFs, in order to speed up the measurement process and make the measurement more user-friendly. However, that work was primarily focused on identifying the stable spindle speeds or was limited to specific tools (Snyder et al. 2001). This paper focuses on a method to dynamically (i.e. as the tool is rotating) measure FRFs and to construct stability lobe diagrams.
