Abstract
The grinding of flat parts from 06Cr14Ni6Cu2MoVaTi-SH high-strength corrosion-resistant steel was made by the highly porous wheel (HPW) of CBN30 (B76, B107, B126, V151) 100 OVK27-KF40 (GOST R 53922-2010, GOST R 53923-2010). As input variables for fuzzy logic modeling in the Matlab the following description of the surface quality is chosen: the microrelief parameters (GOST 25142-82) - Ra1, Rmax1 in the cross-feed direction, Sm2 in the length feed direction, flatness deviation (GOST 24642-81) are introduced with the EFEmax, EFEa and EFEq; microhardness HV. Every parameter at the model input is presented with position measures (medians) and scattering measures (quartile latitude). The Matlab modeling has shown that the best quality of the part surfaces is provided with HPW CBN30 B151 during the multicriteria optimization.
