AN ANALYTICAL RESEARCH OF CHIP COMPRESSION FACTOR IN ORTHOGONAL TURNING MECHANISM OF AISI 1050 STEEL

Oktay Adıyaman1 , Musa KILIÇ 2

Numerous parameters are influential on-chip compression factor, surface roughness, and chip morphology. This experimental study investigated the effect of the chip compression factor on machinability. In this context, the influences of feed rate, cutting depth, rake angle, and chip slenderness ratio on-chip compression factor and surface roughness were investigated. Additionally, the orthogonal shear mechanism and shear strain were analyzed according to D'Alembert's principles of motion. The effect of parameters on the chip compression factor was analyzed with the help of the Matlab program according to the orthogonal cutting mechanism, shear strain, and D’Alembert’s motion principles. It was observed that surface roughness increased steadily with increasing cutting depth and feed, but decreased linearly with rake angle and chip slenderness ratio values. According to the machinability criterion, the most appropriate chip slenderness ratio value was 15, but the chip compression factor value was between 1.7 and 2.3, which aligns with the literature results. Furthermore, concerning experimental and analytical values of both chip compression factor and shear strains, it was determined that the shearing process came true at a 35O shear angle in turning of AISI 1050 steel.
