Experimental determination of the deformation rate in turning
The article discusses the method of experimental determination of deformation in the area of chip forming in the process of free turning of copper M1. To conduct the study the method of digital image correlation was used. The value and direction of a deformable material movement were determined by using special software. Based on experimental data, components of deformation rate and its intensity were calculated. The coincidence of the results with earlier studies conducted by means of dividing grids proves the validity of the method of digital image correlation for studying deformation processes occurring in the area of chip forming.
