Abstract:
Theoretical studies of peripheral milling and the results of simulating
the construction of a 3D relief of the machined surface have been presented. A
digital model of the surface relief formation during peripheral milling with an end
mill has been developed. The related simulating algorithm has been created. The
milling process model is compiled taking into account the dynamic phenomena
occurring in a closed technological machining system (TMS) and machining along
the trace, represented by a function of a delay argument. The dynamic system is
represented by a single-mass model with two degrees of freedom. The created
application program for simulating peripheral milling with an end mill makes it
possible to predict the power parameters of the cutting process and the geometric
and machining parameters, depending on the geometric parameters of the cutter
and workpiece, cutting mode, and dynamic characteristics of TMS. A 3D relief
of the machined surface has been constructed. Its geometric component consists
of the shape of micro-roughness, formed from the geometric engagement of the
cutting edge of the helical mill with the workpiece and the elastic movement of
the TMS. Simultaneously, it corresponds to the interaction of the next cutter tooth
along the helix. The created application program makes it possible to predict the
microrelief of the machined surface depending on the main TMS parameters.
