Modeling and Optimization of WEDM of Titanium

Applied Mechanics and Materials, 2015
Wire-electro discharge machining (WEDM) is one of the important non-traditional machining processes used to machine difficult-to-machine materials and complicated profiles. Being a high degree of complexity process, it is unfavourable to determine optimal parameters for improving cutting performance.

An investigation on wire wear in WEDM

Journal of Materials Processing Technology, 2003
Abstract In this study, the effect of cutting parameters on wire electrode wear was investigated experimentally in wire electrical discharge machining (WEDM). The experiments were conducted under different settings of pulse duration, open circuit voltage, wire speed and dielectric fluid pressure.

Entrance mark control on precision WEDM

Journal of Materials Processing Technology, 2004
Abstract A tiny hollow space on the interface between the approach and the machining path may cause critical damage during superfine machining by wire-cut electrical discharge machine (WEDM). This paper points out that this space is caused by the reduction of the machined volume near the approach point.

Application of RBF Neural Network in WEDM

Advanced Materials Research, 2012
It is difficult to build a strict mathematical model for WEDM due to the complication of the machining process and the nonlinear relation between process parameters and process targets. The neural network is suited to the modeling of complex system, because it has the functions of self-organized, self-learning and associative memory, and properties of ...

Microstructural characteristics of pure titanium by WEDM

International Journal of Microstructure and Materials Properties, 2014
In this research work pure titanium was machined with WEDM process with zinc coated wire electrode having O0.25 mm. Experimentation was conducted as per Taguchi's L27 orthogonal array for investigating the influence of process parameters such as pulse on time (TON), pulse off time (TOFF), peak current (IP), wire feed (WF), wire tension (WT) and servo ...

Measurement of wire electrode temperature in WEDM

The International Journal of Advanced Manufacturing Technology, 2008
Wire temperature is an important parameter in the wire electro-discharge machining (WEDM) process because overheating of the wire can cause the wire to break. It is difficult, however, to measure the wire temperature directly under the condition that the wire is emerged in water and surrounded by the workpiece.

Performance evaluation of WEDM by application of MOGA

Materials Today: Proceedings, 2020
Abstract The phenomenon of spark erosion for forming complex profiles on conductive materials is applied in WEDM. In current research D3 die tool steel is assessed in terms of two conflicting responses i.e. surface roughness (Ra) and material removal rate (MRR).

ANN for Interpolating Instability Trends in WEDM

IFAC Proceedings Volumes, 2008
Abstract In Wire Electrical Discharge Machining (WEDM) the breakage of the cutting tool (the wire) reduces the process performance and the required accuracy. Previous works of authors showed that the behavior of the basic signals of the process (current and voltage) can be employed to detect degraded situations that can lead to wire breakage.

Machining phenomena in WEDM of insulating ceramics

Journal of Materials Processing Technology, 2004
Abstract Recently, an electrical discharge machining (EDM) method of insulating ceramics was proposed by the authors. This paper describes the arbitrary shape machining method of Si 3 N 4 insulating ceramics by WEDM. In the WEDM of thick workpieces of Si 3 N 4 insulating ceramics, wire breakages occurred frequently. To avoid the breakage conditions,
