In this article we will discuss about the economics of machining. It is not sufficient to devise a feasible procedure for a desired component or commodity. The procedure must be economically justified. The variables affecting the economics of a machining operation are numerous which include the tool material, machine tool capacity and the cutting conditions. […]

Structure of ECM Machine | Machining | Industrial Engineering
Article shared by :
The typical ECM machine consists of a table for mounting the workpiece. The tool is mounted on a quill fixed on a ram. Vertical box frame structure has excellent rigidity required and is best suited for precision work. Vertical C-frame structure has less rigidity but offers greater accessibility to the workpiece and tooling. The machine […]

Process of Electrochemical Wire Cutting (ECWC) | Industries | Metallurgy
Article shared by :
Electrochemical wire cutting process for removal of metal using a wire tool as cathode and workpiece as anode. The workpiece can be shaped by relative movement between it and the wire. The process is similar to wire discharge machining. This process is found to be best suited for cutting in one or two directions and […]
