Wire-EDM geometrical simulation based on superposition of single craters
(2023)Procedia CIRP ~ 19th CIRP Conference on Modeling of Machining OperationsSetting EDM technology parameters is a time consuming and expensive process. The development of a process model facilitates the understanding of the input parameters on the process results, which can speed up the selection of the optimal technology for a cut. This work aims to model the wire-EDM machining process with a three-dimensional geometrical voxel model through the sequential placement of single craters. To model workpiece sizes ...Conference Paper -
Geometric-kinematic model for wear simulation of diamond-impregnated segments in concrete core drilling
(2023)Procedia CIRP ~ 19th CIRP Conference on Modeling of Machining OperationsThe main concerns during the development of new diamond-impregnated segments in concrete core drilling are the tool lifetime and its capacity to self-sharpen, since tool sharpening is, most of the time, not acceptable under the conditions on the construction site. However, development only based on experiments can be very costly, considering that the amount of material and workforce are quite demanding. One of the solutions to overcome ...Conference Paper -
iMFREE: A versatile software tool for modelling machining processes with particle methods
(2023)Procedia CIRP ~ 19th CIRP Conference on Modeling of Machining OperationsThe current state-of-the-art for the simulation of machining process is the application of the FEM (finite element method). Nevertheless, the cost of FEM analyses for such problems is high due to their complex multi-physics nature, mesh regeneration issues, and small time-length scales. In contrast, particle methods are an alternative numerical approach well-suited for large deformations as in material's chip formation. In this work, the ...Conference Paper -
Study on the effect of wear models in tool wear simulation using hybrid SPH-FEM method
(2023)Procedia CIRP ~ 19th CIRP Conference on Modeling of Machining OperationsThe prediction of the tool wear progression using numerical methods has been widely studied in recent years, and various wear models considering different wear mechanisms have been implemented in the simulation work. Typically, these wear models take the physical fields such as contact pressure, sliding velocity and temperature at the tool-workpiece interface into account and are applied either individually or in combinations into the ...Conference Paper
