(2014) Reliability assessment of cutting tool life based on surrogate approximation methods, International Journal of Advanced Manufacturing Technology, Vol. 71, Iss. 5-8. pp. 1197-12080268-3768http://dx.doi.org/10.1007/s00170-013-5560-2https://dspace.lib.cranfield.ac.uk/handle/1826/10484A novel reliability estimation approach to the cutting tools based on advanced approximation methods is proposed. Methods such as the stochastic response surface and surrogate modeling are tested, starting from a few sample points obtained through fundamental experiments and extending them to models able to estimate the tool wear as a function of the key process parameters. Subsequently, different reliability analysis methods are employed such as Monte Carlo simulations and first- and second-order reliability methods. In the present study, these reliability analysis methods are assessed for estimating the reliability of cutting tools. The results show that the proposed method is an efficient method for assessing the reliability of the cutting tool based on the minimum number of experimental results. Experimental verification for the case of high-speed turning confirms the findings of the present study for cutting tools under flank wear.enAttribution-Non-Commercial-No Derivatives 3.0 Unported (CC BY-NC-ND 3.0).
