Performance of wiper geometry carbide tools in face milling of AISI 1045 steel

Face milling tests on AISI 1045 steel were performed to study the flank wear of multilayered coated carbide tools. The cutting tools were dual (TiN/TiAlN) and triple (TiN/Al2O3/TiCN) layered, coated carbide inserts processed by PVD and CVD respectively. As expected, the depth of cut (DOC) did not play an important role on the development of flank wear while the cutting speed had a significant role in the development of flank wear. Using confocal laser scanning microscopy (CLSM) and wavelet transform, the flank wear evolution was analyzed and abrasive wear was found to be a dominant tool wear mechanism. Adhesion of the work material was also observed after the carbide substrate was exposed. Edge chipping and micro-fracture were additional tool failure modes. After comparing the performance of the two inserts, we concluded that the dual layer coating was superior to the triple layer coating under various cutting conditions mainly due to the benefit coming from the coating processes themselves. It was claimed that the superior performance of the multilayer coating came from preventing the gross crack-induced removal of coating materials by propagating the fracture along the coating interfaces. However, no such observations were found in our milling experiment. Therefore, the hardness of the coating materials is the most important criteria for the development of flank wear.

The objective of the present work is to simulate surface roughness in Computer Numerical Controlled (CNC) machine by Fuzzy Modeling of AISI 1045 Steel. To develop the fuzzy model; cutting depth, feed rate and speed are taken as input process parameters. The predicted results are compared with reliable set of experimental data for the validation of fuzzy model. Based upon reliable set of experimental data by Response Surface Methodology twenty fuzzy controlled rules using triangular membership function are constructed. By intelligent model based design and control of CNC process parameters, we can enhance the product quality, decrease the product cost and maintain the competitive position of steel.

AbstractQuench hardening aims at the microstructural transformation of steels in order to improve hardness and mechanical strength. The aim phase is, in most cases, the martensite. It is necessary to heat the material until it obtains its austenitization and quenching by immersion in a fluid. Currently, it is common to use watery polymeric solutions in this procedure. These fluids, which are the mixture of polymers in water, vary their thermal exchange capacity depending on the concentrations applied. The increase in concentration minimizes the removal of heat from the part, reducing the formation capacity of martensite, and developing a lower hardness and strong steel. In this work, microstructural characteristics and properties of AISI 1045 steel quenched in solutions based on polyvinylpyrrolidone (PVP) in 10, 15, 20, and 25% concentration were evaluated. The microstructural characterization quantified the percentage of the phases in each concentration, demonstrating a reduction of martensite as the concentrations were high. The investigation of the samples by x-ray diffraction confirmed the absence of austenite retained in the material. Furthermore, a microhardness scale between the core and the surface was constructed, in which a reduction gradient of the indices of this property towards the core of the sample was evidenced.
