Force coefficients are required for mechanistic force calculations in machining operations. The
mainstream method of identification of force coefficients relies on dynamometers. However,
using dynamometers is not necessarily applicable. This paper offers a method of force
coefficients identification without force measurement. A specially designed workpiece is milled.
Its acceleration is utilized together with FRFs obtained on the same milling machine that the
acceleration is measured. Force estimation is performed with acceleration data and FRF.
Force model is curve-fit with recursive least squares method into force estimation in order to
find force coefficients.
