Non Conventional Machining Process Ppt [top] Direct
Creating intricate shapes, micro-holes, or complex internal cavities is nearly impossible with standard drills or mills.
This process works on the principle of reverse electroplating. A tool (cathode) is brought close to a conductive workpiece (anode) while a high-flow electrolyte, such as sodium chloride (NaCl) or sodium nitrate (NaNO₃), is passed between them. Material is removed by controlled electrochemical dissolution, atom by atom. ECM is capable of very high material removal rates and leaves a flawless, burr-free surface, making it excellent for producing complex parts like turbine blades and fuel injection nozzles.
Non-conventional machining processes are not meant to replace traditional manufacturing entirely, but rather to complement them. By understanding the distinct mechanisms, limitations, and advantages of thermal, chemical, and mechanical advanced machining, engineers can choose the right process to bring complex, modern designs to life with unmatched precision.
Traditional tools break when cutting superalloys, ceramics, and composites. Non Conventional Machining Process Ppt
The tool and workpiece rarely make physical contact, eliminating tool wear from friction.
Injection mold manufacturing, stamping dies, and machining complex aerospace components. Electrochemical Machining (ECM)
: Removes material atom-by-atom via electrolysis . Electrical Discharge Machining (EDM)
Non-conventional machining, also known as non-traditional or unconventional machining, refers to a group of material removal processes that do not use a traditional sharp cutting tool. Instead, they utilize various forms of energy, such as mechanical, thermal, electrical, or chemical energy, to remove material from a workpiece.
Non-conventional machining is not a replacement for traditional methods but a necessary evolution. As industries move toward aerospace, nuclear, and electronic applications, the reliance on NCMP will only grow.
High precision and mirror-like surface finishes are required without inducing residual stress. 2. Classification of Non-Conventional Machining Processes Laser Beam Machining (LBM)
Utilizes a high-velocity stream of focused electrons in a vacuum chamber to vaporize precise areas of the material.
Producing micro-holes, deep blind cavities, or intricate profiles is incredibly difficult with physical cutting tools.
