JSPE Takagi Award
■Winning Theme：”Application of a novel woven metal wire tool with electrodeposited diamond grains for carbon fiber reinforced plastics core drilling, Precision Engineering, 56 (2019) pp.386-394.”
Professor Sasahara developed a new tool electrodeposited with diamond abrasive on cylindrical wire mesh that is used for core drill. This tool is able to reduce the cutting areas as it is made of a thin cylindrical wire mesh, and suppression of delamination is expected as the axial machining force is significantly reduced. Further with this tool, the chips can easily slip from the gaps of the wire mesh thus this can avoid clogging. Therefore, when it comes to drilling carbon fiber reinforced composite material (CFRP), such material used in aircrafts, both great reduction of chips in drilling and maintaining fine surfaces were achieved with the application of this tool.
The award is presented annually to the author(s) of seminal paper(s) with high originality and excellent industrial value in the field of precision engineering, and it aims to promote further industrial activities in its field.
