Sažetak
Machining chips are affected by physical, technological and economic parameters of changing character. Considering the complexity of a series of factors influencing the cutting process, efforts are made to apply the patterns observed in the simplest chip machining process to other processes. The simplest type of machining chips is orthogonal cutting. The aim of this paper was to determine theoretically and experimentally chip plastic deformations in the process of orthogonal wood cutting. Orthogonal cutting is the process of conversion of a part of workpiece (undeformed configuration) into chips (deformed configuration), and the relationship between the non-deformed and deformed configuration is described as the strain tensor. Continuum mechanics was used as background for theoretical analysis, and wood was considered as an orthotropic material. The experimental research was carried out on samples of pine (Pinus sylvestris L.) with no visible wood defects and with an approximately equal share of the early and late wood. Pine samples were conditioned to a moisture content u = 10, 14, 30 and 45 %. Orthogonal cutting of samples was carried out by the movement of the workpiece and the processing parameters were customized in order to get continuous chips. In order to determine experimentally the chip plastic deformation, the cutting process was recorded with a high speed camera Olympus I - SPEED 2. Subsequently, chip compression coefficients were determined from the camera’s recording, depending on the samples moisture content and cutting speed.
