Abstract
The turning process with varying spindle speed is investigated. The well-known turning model is presented and the governing delay-differential equation with time varying delay is analyzed. Three different numerical techniques are used to solve the governing equation: (1) direct Euler simulation with linear interpolation of the delayed term, (2) Taylor expansion of the time delay variation combined with Euler integration and (3) semi-discretization method. Stability charts are constructed, and some improvements in the process stability is shown, especially for low spindle speed domain.
