Electrochemical machining is the opposite process to electrochemical or galvanic coating. In electrochemical machining, the workpiece is taken as the anode, and the tool is taken as the cathode. These are both placed in an electrolyte solution and an electrical current is …
Electrochemical machining (ECM) is a metal machining process involving the removal of material from a workpiece by means of electrochemical erosion. This process is achieved by passing a high current electrical charge from the positively charged workpiece through an electrolyte solution to the negatively charged "cutting tool.".
What is Electrochemical Machining? Electrochemical machining is a process of removing metal with the help of the electrolysis process. The electrochemical process is also known as the reverse of the electroplating process because, in electroplating, the metal is deposited on the surface of the workpiece, while in electrochemical machining the metal is removed from the workpiece.
Pulsed electrochemical machining (PECM) is a manufacturing process for complex shaped products with structures or surface geometries in the sub-mm range [9, 10]. In PECM, the material is removed, based on anodic metal dissolution, by applying a pulsed voltage between the anode (tool) and the cathode (workpiece).

Electrochemical Machining (ECM) is a comparatively simple and cheap process, especially with modern 3D . To put it simply, ECM is using saltwater and a conductive material like copper wire in order to rust the rifling grooves in a controlled manner.
With electrochemical machining, a pressurised conductive salt solution, the electrolyte, flows around the workpiece as an electrical– chemical reaction de-plates material from the workpiece. It is the opposite of the classic plating process.
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. The electrochemical machining process is a function of electrochemistry: the branch of physical chemistry concerned with the relationship between electrical potential, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electrical potential as an outcome of a ...

Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
Both ECM and ECM are non-conventional machining methods; however, that one letter makes a big difference! EDM, or electrical discharge machining, relies on localized spark erosion to remove material, whereas ECM, or electrochemical machining, utilizes electrolysis to dissolve the metal locally. We will explore some of the other differences, similarities, and advantages of each below.

Electrochemical machining is a process of a selective dissolution of the anodically connected work piece material submerged in an electrolyte together with an anodically connected tool. Principally electrochemical machining is similar to Electropolishing where the work piece surface roughness decreases due to the conversion of the atoms into ions and their removal from the surface …
In Electrochemical Machining it machined those material which are conductor of electricity. In this the bad conductor or semiconductor material is not machined. In this electrolyte is used since there a chance of corrosion of tool. Difference Between Electrochemical Machining and Electrical Discharge Machining:
Electrochemical Machining Definition: Electrochemical Machining (ECM), characterized as non-traditional machining, is an advanced machining, non-contact, reverse electroplating process (ECM removes material instead of depositing it). In ECM, a high electric current is passed between the tool and workpiece through a conductive fluid.
Electro-Chemical Machining (ECM) EDM is thermal energy based non-traditional machining process. ECM is electrical energy based non-traditional machining process.

Electrochemical machining is founded on the principles outlined. As shown in Figure 3, the workpiece and tool are the anode and cathode, respectively, of an electrolytic cell, and a constant potential difference, usually at about 10 V, is applied across them.A suitable electrolyte, for example, aqueous sodium chloride (table salt) solution, is chosen so that the cathode shape remains unchanged ...
Electrochemical machinings are a non-traditional machining process. In the electrochemical machinings process, a combination of electrical energy & chemical energy is used to remove material from the workpiece. This process is known as a reverse electroplating process, but this process removes the material rather than depositing it.
The electrochemical machining (ECM) process electrochemically dissolves material -- "reverse electroplating" -- until only the desired shape remains. Similar processes are Electrical Discharge Machining (EDM) and Electrochemical Discharge Machining . A RepRap has the potential to make metal parts or even its own circuit boards.
