Application of the Monte Carlo Method for the optimization of surface roughness during precise turning of NiTi shape memory

This study was carried out to understand precise turning of NiTi shape memory alloy with the tools with edges made of polycrystalline diamonds (PCD) and consisted of three stages: experimental work, modelling of function, optimization by Monte Carlo method use. In the first stage (experimental work), precise turning experiments were carried out using Taguchi method. The effects of cutting speed and feed on the surface roughness (Sa and Sz) were investigated. In the second stage (modelling), all data gathered in the experimental work were utilized to formulate models with interaction using the response surface method. In the third stage Monte Carlo method for solving machining optimization problems was used. The present paper has main objectives: to develop a framework for solving machining optimization problems using the Monte Carlo method.
