Abstract: Acoustic emission (AE) generated during simple upsetting (forging) of solid cylinders contains information that could potentially be used to separate the upsetting process into a range of zones ...

Abstract: An analytical model for drilling burr formation was developed. The model holds for ductile materials that do not show catastrophic fracture during the plastic deformation of workpiece material ...

Abstract: Accurate models of two-flute conical twist drills are needed for finite element simulations of the drilling process. Existing drill designing methods rely extensively on discretized analytical ...

Abstract: The mechanisms of burr formation and breakout in orthogonal cutting are analyzed. A burr formation/breakout model for orthogonal cutting is proposed, based on the observation of SEM micro-machining ...

Abstract: Sensor feedback for process control is one of the essential elements in an automated deburring procedure. This paper presents the implementation of acoustic emission (AE), which has been developed ...

Abstract: The purpose of this study is to develop an effective way of automated deburring of precision components. A high power laser is proposed as a deburring tool for complex part edges and burrs. ...

Abstract: Theoretical relationships have been drawn between acoustic emission (AE) and the metal cutting process parameters by relating the energy content of the AE signal to the plastic work of deformation ...

Abstract: A quantitative model of burr formation for ductile materials which does not include fracture during orthogonal machining is proposed. The burr formation mechanism is divided into three parts—initiation, ...

Abstract: Atomic layer deposition (ALD) is a promising nanotechnology for wide applications in microelectronics manufacturing due to its ability to control layer growth at atomic scale. Sustainability of ...
