Reverse Engineering Representation Using an Image Processing Modification

open access: yesAl-Khawarizmi Engineering Journal, 2019
In the reverse engineering approach, a massive amount of point data is gathered together during data acquisition and this leads to larger file sizes and longer information data handling time.

Dynamic cutting process modelling and its impact on the generation of surface topography and texture in nano/micro cutting [PDF]

open access: yes, 2009
In the nano/micro cutting process, the surface quality is heavily dependent on all the dynamic factors, including those from the material, tooling, process parameters, servo accuracy, mechanical structural stiffness, and non-linear factors as well.
