The knurling of corrosion-resistant steel 95X18 (the nearest analog is AISI 440B, AISI 440C, AISI A756, DIN-1.4125, SUS440C, Z100CD17) simulation with finite element method is investigated in the paper. Diagram stresses, strains and displacement are calculated by using CAE system SolidWorks. Dependence of strengthening area on processing tools geometry and loaded force are investigated. We proposed the algorithm of knurling parameters optimization by using a computer simulation. The correlation between simulation and experimental data was found.
