Programming spindle speed variation in turning
Eastern-European Journal of Enterprise Technologies, 2017 A mathematical model for the turning process is developed, which considers the oscillations of technological machining system (TMS) in a 3D space, along all three coordinate axes simultaneously. The model accounts for the influence of natural feedback on the depth, feed and cutting speed; moreover, the effect of machining by chatter marks is introduced
