Unconventional machining process finds lot of application in aerospace and precision industries. It is preferred over other conventional methods because of the advent of composite and high strength to weight ratio materials, complex parts and also because of its high accuracy and precision. Usually in unconventional machine tools, trial and error method is used to fix the values of process para...

Cryogenic treated high carbon high chromium alloy cold tool steels (D-3) are used in production of high performance dies, punches, blanking and punching tools, extrusion tools, etc. cryogenic treatment is a process of keeping the specimen in cold environment to increase its wear resistance and relieving its residual stresses. Due to its high hardness Wire Electric Discharge Machine (WEDM) seems...

Present manufacturing industries are facing challenges from these advanced materials viz. super alloys, ceramics, and composites, that are hard and difficult to machine, requiring high precision, surface quality which increases machining cost. To meet these challenges, non-conventional machining processes are being employed to achieve higher metal removal rate, better surface finish and greater...

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. In particular, different types of degraded behaviors in two c...

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf wi...

Increasing the machining efficiency of middle speed wire electrical discharge (MS-WEDM) is usually through optimizing process parameters, but servo parameters controller can also be optimized to achieve same purpose. This paper develops a multi-mode for MS-WEDM investigate parameters. Firstly, structure and control principle are introduced, core functions described in detail. Secondly, it intro...
