DOMANDE WATERJET 2023-01-20 What would be the objective of using multiple intensifiers in staggered phases? o The reason is to reduce the risk of complete failure of the system o The objective is to a system in parallel where the pressure is the same, but flow rate is proportional to the number of intensifiers o The reason is to increase the overall pressure generated by the system o The reason is to erase as much as possible pressure variations Consider the different technologies studied in the course for the cutting of 2d metal sheets, in some cases the kerf is not symmetric, (i.e. the tapers of the left and right walls are different). Among the following sentences, select the CORRECT ones (multiple choice possible): o It sometimes happens as a defect in melt and blow laser cutting, when the M2 parameters is too high o It very frequently happens as a defect in plasma arc cutting, because of the gas swirling rotation o It is frequently obtained intentionally, so to have one wall with no taper on the part side and the other wall (the scrap side) with a large taper on it o It sometimes happens as a defect in wire EDM, because of the Lorentz force o It very frequently happens as a defect in AWJ, because of the asymmetry of the suction process 2023-07-20 Fine blanking is the traditional method for producing, with very good precision, the construction steel (C45) gear part shown in the figure, 4 mm thick. After blanking, the part is quenched and tempered to provide its final strength. Consider the removal AMP technologies we have studied as an alternative method for a pre-series production. Which of the following sentences is correct? o All of the material removal technologies (LBM, AWJ, EDM, USM, etc.) we have studied in AMP can be technologically feasible for this…
