When the built-up-edge becomes unstable and large, it results improved surface finish.
The use of the flat secondary edge was observed to improve surface finish when machining a flat surface.
Hard PVD coating with low thermal conductivity and improved surface finish should be used in this case.
Different types of forming tools and toolpath strategies are explored to improve surface finish and geometrical accuracy by using a customized DSIF machine.
As a result, a higher degree of strain hardening with the ground surface reduced the rubbery or adhesive behavior and improved surface finish after grinding, although a large amount of smearing areas remained.
Currently the main focus in development of forming tools is on improving their galling resistance, mainly by including new forming tool steels, improving surface finish, and applying surface treatments and coatings.
Although the efforts towards improving surface finish have been made over the past decades, the recent developments in science and technology accelerate the progresses made towards superior surface characteristics.
However, due to the limitation of the achievable surface quality attributed to defects such as burrs and tool marks, a post-polishing process which can maintain the shape of micro features while improve surface finish becomes an indispensable step.
This machining process provides a key for development of a hybrid rapid prototyping system, which will have features of both layer-by-layer machining and deposition simultaneously, in order to achieve improved surface finish and functionality of RP parts.
There is a strong desire in industry to improve surface finish when performing ultra-precision, single point diamond turning (SPDT) to reduce the amount of post process polishing required to meet final product specifications.
