Abstract
The study uses rigid-plastic finite element (FE) DEFORM TM 3D software to investigate the plastic deformation behaviour of spiral flat bottom engraving. The finite element analysis assumes that the spiral flat bottom is a rigid body. During the engraving process, the deformation causes an increase in temperature and wear inside the blank. The FE analyses investigate the effects of cutting speed, depth of cut, and the feed of the workpiece on the damage, effective strain, stress, temperature, and wear induced within the workpiece. The simulation results confirm the suitability of the DEFORM TM 3D software for modelling the spiral flat bottom engraving. Comparisons of engraving of spiral flat bottom with clockwise and counter-clockwise have been performed. The analysis of following stress-strain simulation has been predicted by machine learning in this study. Eventually, the experiment of spiral flat bottom engraving is used.
