Non Traditional Machining Processes Pk Mishra Pdf 225 Jun 2026
While digital PDFs are convenient, invest the time to read the physical book. The diagram of the ECM equilibrium gap on page 225, when viewed in high-resolution print, will make the concept of “overcut” click in a way that a low-res PDF cannot replicate. Master page 225, and you master a significant chunk of NTM.
| Feature | Traditional Machining (Lathe/Milling) | Non-Traditional (ECM, EDM, LBM) | | :--- | :--- | :--- | | | Physical contact (causes tool wear) | No physical contact (No tool wear in ECM) | | Material Hardness | Harder materials require slower speeds | Hardness is irrelevant (machines by chemical/thermal action) | | Surface Integrity | Can leave residual stresses and burrs | Burr-free, stress-free surface (ideal for aerospace) | | Energy Form | Mechanical (Shear/Tension) | Electrical, Chemical, Thermal, Optical |
Unlike traditional methods that rely on physical contact and a tool harder than the workpiece, NTM processes use various forms of energy (mechanical, thermal, chemical, or electrochemical) to remove material.

Non-Traditional Machining Techniques in Manufacturing Industries While digital PDFs are convenient, invest the time
Non-traditional machining processes have several advantages over traditional machining processes, including:
Similar to LBM but uses a focused beam of high-velocity electrons. When electrons strike the workpiece, their kinetic energy converts into heat, vaporizing the material. EBM requires a vacuum chamber, making it slower but extremely precise. brittle materials such as glass
Where:
LBM uses the thermal energy of a high-power laser beam to cut or drill holes. It is a non-contact process that offers incredible precision.
Whether you are preparing for an interview at ISRO, a GATE exam, or designing a new process for a defense manufacturing unit, the clarity provided by P.K. Mishra on that specific page is invaluable.
AJM is a mechanical process that uses a high-velocity jet of gas mixed with abrasive particles (like aluminum oxide or silicon carbide) to erode material from the workpiece. It is ideal for cutting hard, brittle materials such as glass, ceramics, and silicon.
