What is the current research trend in machining field?
Can anyone post the answers please
Machining of materials difficult to cut
Sustentable machining
Cryogenic machining
Dynamic behaviour
Microgeometry cutting edge of tools modified by LST
Energy efficiency of machining operations,
sustainable machining,
MQL machining etc.
Current trends in machining are to work on the development of sustainable machining process ( Environmental and Economic sustainability) for machining of advanced materials like superalloys, composite and high strength steels etc.
In this for process sustainability researchers are working on first on advancements in cutting tools like (advanced wear resistant nano-coatings on tools, special composites for fabricating the tool through powder metallurgy, special tool edge geometries/ texturing on the tool rake surface, special arrangements for enhancing the cutting fluid supply near to the cutting zone, cryogenic treatment of tool inserts etc. ), secondly enhancing the damping quality and strength of tool holder through variations in geometry and shapes of tool holder and even some special arrangement of micro holes for enhancing the coolant supply through tool holder, thirdly for process characteristics measurement online condition monitoring, effective cutting zone temperature measurements through embedded thermo-couples, Then researchers are working to use sustainable cutting/ lubrication fluids and methods like use of chilled air through vortex tube, only compressed air, cryogenic cooling, use of edible and non edible oils along with nano-particles and even some advancements in MQL process like use of hybrid fluids and use
Electrostatic Minimum Quantity Lubrication. Then working to ensure best surface characteristics/ integrity of the machined workpiece using advanced measuring techniques like Nano indentation methods, use of TEM and XRD for surface characteristics analysis.

Hi Mr Dennison,
You can look for Sustainable Micro and Nano machining.

Excellent set of pointers have been provided by the earlier respondents. I am going to add one more. Dry machining with coated cutting tools. Hybrid (hard phase + soft lubricating phase) coated tools can be used for dry machining at high speed as documented in the article below:
