ON THE CUTTING FORCES TO THE DRILLING OF THE STAINLESS STEEL W1.4571
Ovidiu BLĂJINĂ, Aurelian VLASE, Ion ION
Abstract: The paper presents the experimental results necessary for the regression relations for the cutting forces when drilling the stainless steel W1.4571. For this purpose a rotate dynamometer was designed, fixed in the conical space of the drilling machine, provided with tensometric traducers linked on an elastic element that assures a sufficient sensibility for the established purpose. The range of the cutting forces of 450 ... 9500 N permitted experiments with drills of 6 ... 32 mm diameters. Through many experiments, the necessity of changing the structure of the relation of the forces was proven, by introducing the relations (2) and (5).
Key words: axial force, cutting forces, stainless steel, polytropic exponents.
