Energy Dissipation Control in Hydro-Abrasive Machining Using Quantitative Acoustic Emission
نویسندگان
چکیده
The efficiency and product quality of hydro-abrasive machining (HAM) could be considerably improved if the energy dissipation phenomenon of the jet-like tool during the material removal is clearly understood. An on-line technique for quantifying the amount of energy dissipated in the workpiece during HAM using acoustic emission (AE) measurements is presented in this paper. The measured AE-signals are linked to a physical energy dissipation model. Stochastic modelling of the AEsignals provides more information on the physics of the energy dissipation process.

متن کاملCharacteristics of Acoustic Emission Signals in Machining Using Diamond Coated Tools
Diamond coated cutting tools have been pursued as a costeffective substitute to brazed polycrystalline diamond (PCD) tools in applications such as machining high-strength and lightweight materials. However, coating delamination has been known as the major failure mode of diamond coated tools, which terminates tool life prematurely. Once delamination failure occurs, the tool substrate often subj...
