A New Load Cell Dynamometer for Measuring the Dynamic Cutting Coefficients

  • R. Radharamanan


A new two component load cell dynamometer [1] has been designed in order to measure the dynamic cutting force components in an orthogonal turning process more accurately without any cross influences. The new load cell dynamometer and a digital Fourier analyser along with the refined experimental setup have been used to measure accurately the dynamic cutting coefficients. From the experimental results, the effects of excitation frequency and cutting speed on the components of dynamic cutting have been analysed.

A programmable mathematical model has been derived to evaluate chatter depth, phase angle and chatter frequency from the stability criterion and the graphical solution developed in the machine tool laboratory of the Katholieke Uhiversiteit Leuven,using the measured dynamic cutting coefficients and the stiffness of the model structure.

Useful conclusions are drawn from the measurements and the analysis.
