Question
The primary mechanism of material removal in electrochemical machining (ECM) is:
Solution
The primary mechanism of material removal in Electrochemical Machining (ECM) is electrochemical dissolution. Here's a step-by-step explanation:
-
Electrolyte Supply: In ECM, an electrolyte (such as sodium chloride solution) is pumped at high pressure into the gap between the workpiece and the tool (also known as electrode).
-
Electric Current: A direct current is passed between the workpiece and the tool. The workpiece is the anode (positive terminal), and the tool is the cathode (negative terminal).
-
Electrochemical Reaction: The electric current causes an electrochemical reaction to occur, which dissolves the metal from the workpiece. The metal from the workpiece is dissolved as metal ions. This process is similar to the process of rusting, but it occurs much more quickly.
-
Ion Transportation: The dissolved metal ions are transported away from the workpiece by the flowing electrolyte.
-
Material Removal: As a result, material is removed from the workpiece, and the desired shape is obtained. The rate of material removal is controlled by controlling the current density.
So, the primary mechanism of material removal in ECM is the electrochemical dissolution of the metal from the workpiece.

Read the text and fill in the blanks WITH ONLY ONE WORD.Machining and CNCMaching is the use of machines to cut pieces of material (called workpiece) and shape them into components. The tools used in machining, to make holes, grooves, threads, etc., are called machine tools. Metal is often machined. As it is cut, waste is produced, called swaft or chips. During machining, a liquid called cutting fluid may be pumped onto the workpiece to act as a coolant, keeping the workpiece cool. In manufacturing, machining is usually guided by computers called computer numerical control (CNC) systems. Often, design information ( on shapes and sizes of components) is fed directly into CNC systems from computer aided design/ computer aided manufacturing (CAD/CAM) software.Machining with cutting toolsMilling is cutting done by a milling machine, often using toothed cutting discs ( wheel with teeth that have sharp edges). When a workpiece is milled, it is held in a fix position on the machine, and is shaped by cutting tools which rotate (spin) while being moved over the surface of the workpiece.Turning is a technique for cutting components that have a circular cross-section. The workpiece is turned by a machine called a lathe, which rotates the workpiece. A fixed machine tool is then moved against the rotating worpiece to cut material from it.Punching: Thin materials can be cut by applying pressure in order to shear them- that is, cut them with scissoring force ( in engineering, called a shear force). Small shapes, such as circles, can be sheared from sheets using a machine called a punch which pushes a die ( a shaped tool) through the sheet.1. The waste metal produces during machining is called 2. Metal gets hot during cutting, so cutting fluid can be used as a .3. Drawings can be produced and traferred to the machining process using .4. A milling machine uses toothed cutting discs to mill a held in a fix position on the machine.5. Turning means cutting components that have a circular cross-section. A lathe is used to turn and the workpiece.
