Abstract

This chapter describes regenerative chatter in milling. Similar to Chap. 3, both analytical and numerical analyses are presented to predict the process behavior. The analytical, frequency domain stability lobe diagram is adapted to milling. Two algorithms are described: average tooth angle and Fourier series. Time domain simulations for square (straight teeth and helical teeth) and ball endmills (helical teeth) are detailed. The cutting force model is then extended and an experimental procedure for identifying the cutting force coefficients is derived for two different fitting approaches. Finally, the effect of process damping on milling stability at low speeds is presented.

The “old” authors realize that graphic equalizer displays on stereos are not as common as they were in our teenage years. For that matter, they don’t call them “boom boxes” any more, do they? P.S. We are not that old!

We will assume a rigid workpiece in our analysis.

The selection of 67% was arbitrary. It caused the first point to not coincide with the cut entry so that the variation in the sampled force could be clearly observed.

Author T. Schmitz recognizes B. Mann for recommending this function.

Plowing (alternately ploughing), or plastic deformation without material removal, can also occur for significant interference between the tool relief surface and workpiece.

T. Schmitz recognizes the significant contributions of M. Rubeo to the nonlinear optimization analysis.
