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 ...

Material Removal in WEDM of PCD Blanks

Journal of Engineering for Industry, 1994
Polycrystalline diamond (PCD) tools are now widely used in machining a large variety of advanced materials. However, the manufacture of PCD tool blanks is not an economical and efficient process. The shaping of PCD blanks with conventional machining methods (such as grinding), is a long, labor-intensive and costly process.

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).

Study on Finishing Cut with Dry WEDM

Materials Science Forum, 2006
Utilizing gas as the dielectric instead of dielectric liquid has enabled the development of dry wire electrical discharge machining (WEDM) technology for finishing cut. This paper studies on the surface quality of tool steel with WEDM method, which is conducted in gas to improve the accuracy of finishing cut, and compares the surface quality in ...

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,

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.
