Selected Problems of Machine Tool Chatter

Abstract

<p>This work applies previous research in the field of chatter in metal cutting to some practical problems of chatter during metal removal.</p> <p>Investigations into the stability of a machine tool structure were performed in order to make an analysis of the present stability during machining and how the level of stability can be increased.</p> <p>Computation of the dynamic response of a grinding spindle was carried out as an example of a typical procedure usually used in checking a design change with respect to requirements resulting from stability analysis.</p> <p>A practical case of chatter in milling slots in an automobile component was examined. A simplified experimental analysis was used and two possible solutions investigated; one of eliminating regeneration of vibration and the other of using a damper.</p> <p>The last part deals with an attempt to solve the problem of pseudostatic instability in reaming tapered holes.</p>
