On modelling of laser assisted machining: forward and inverse problems for heat placement control (2018)
Journal Article

Laser assisted machining (LAM) is one of the most efficient ways to improve the machinability of difficult-to-cut materials (e.g. Nickel-based superalloys). In the conventional LAM process, the laser beam is focused ahead of the cutting area at a fix...

On modelling of cutting force and temperature in bone milling (2018)
Journal Article

© 2018 Elsevier B.V. Cutting force and temperature are the key factors to be controlled during the orthopaedic surgery which could result in mechanical damage and necrosis of the bone tissue. Mechanistic modelling of the bone cutting process is expec... Read More about On modelling of cutting force and temperature in bone milling.

On understanding the microstructure of SiC/SiC Ceramic Matrix Composites (CMCs) after a material removal process (2018)
Journal Article

The unique material nature (e.g. hard, brittle, heterogeneous and orthotropic) of SiC-based Ceramic Matrix Composites (CMCs) highly affects the outcomes of machining process by inducing high thermo-mechanical loads during material removal. This can r... Read More about On understanding the microstructure of SiC/SiC Ceramic Matrix Composites (CMCs) after a material removal process.

On the inverse design of discontinuous abrasive surface to lower friction-induced temperature in grinding: an example of engineered abrasive tools (2018)
Journal Article

In order to lower temperature, abrasive tools with passive-grinding, e.g. textured, areas (PGA) have been suggested. However, most of the reported PGA geometries (e.g. slots, holes) have been determined based on the engineering intuition (i.e. trial...
