Dynamic Model Of Cutting Process With Modulated Spindle Speed

The paper presents classical regenerative one degree of freedom model of cutting. The model is enriched in an additional friction phenomenon which generates frictional chatter. A mutual interaction between regeneration and frictional effects is analysed to find stability regions. In the second part of the paper a spindle speed variation method is applied for chatter suppression both for classical regenerative model and also for regenerative model with the friction effect. Finally, the map of spindle speed variation parameters is drawn.
