View Electrochemical Machining PPTs online, safely and virus-free! Ultrasonic machining is an abrasive process which can create any material into hard and brittle form with the help of its vibrating tool and the indirect passage of abrasive particles towards the work piece. Wire electrical discharge machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal workpiece. Several experiments are conducted to study the effect of three process parameters: peak current (I p), pulse on-time (T on) and electrode material on the machining process of H13 die steel. The proposed method used vision system. MRR= 1000×( Wb- Wa) /t mg/min TWR= 1000×( Tb–Ta ) /t mg/min Wb : Weight of the work-piece before machining Wa : Weight of the work-piece after machining Tb : Weight of the tool before machining Ta : Weight of the tool after machining Support structures are essential for SLA and FDM, but … 1.

See our Privacy Policy and User Agreement for details. process has been observed to be difficult to establish [1, 2]. 1 Electrical Discharge Machining (EDM) The metal removal process Slideshow search results for surface finish. The favourable EDM process parameters selection is required for obtaining the best machining performance by increasing the production rate at the same time reducing the machining time. • 7. Abrasive Flow Machining Process Principle, Parameters and Capabilities 2. It is a low material removal rate machining process. Work pieces are prepared with varied roughness using manufacturing process of EDM and subjected to different machining parameters such as variable current and voltage.

Arcing leads to localised material removal at a particular point whereas sparks get distributed all over the tool surface leading to uniformly distributed material removal under the tool. The conductivity of the water is carefully controlled making an excellent environment for the EDM process. With an increase in frequency of the tool head the MRR should increase proportionally. A “rough-machined” EDM surface with a cross section through chips and craters. Material: Uddeholm Orvar 2 Microdized. Electrode wear ratio (EWR), material removal rate (MRR) and surface roughness (SR) were considered as the process responses.
