Chaos in a Cutting Process
نویسنده
چکیده
The dynamics of the cutting process are investigated. Using the increase of cutting depth as a control parameter, two diierent cutting regimes are observed. In the rst regime, which is observed at small cutting depths, complex, high-dimensional dynamics occur. In the second cutting regime, observed for deeper cuts, low dimensional dynamics are typical. The second cutting regime is usually identiied as chatter and represents an unfavorable operating condition of the cutting process.

متن کاملInfluence of Tool Flank Forces on Complex Dynamics of Cutting Process
We study complex dynamics of a cutting process, a recently developed frictional model of cutting process in [Rusinek et al., 2014] to gain better insight into the mechanics of frictional chatter and the factors affecting it. The new model takes into account the forces acting on the tool face as well as on the tool flank. We first present nonlinear dynamic behavior using bifurcation diagrams for...
