An economic substitute for the conventional CFRP milling cutters
In the submitted papers, the technical investigation of improving the CFRP grinding process is shown. So different methods have been carried out. One method involves the use of innovative grinding wheel specification and its influence on milling related parameters during the grinding process of end mills. The results show that different bonding systems lead to different grinding forces in the process of groove grinding, and thus may affect the shape and size accuracy of the grinding tools. In addition, it has been proved that during the grinding process, the change of feed speed VF has different effects on the surface quality during the lapping process. The research shows that the influence of grinding process parameters on the surface quality of rake face is remarkable. Because the characteristics of rake face are very important for cutting mechanism, tool manufacturers should take this into account. The upcoming research work will consider the grading grinding tools for groove grinding process, so as to respect the complex and unsteady contact conditions when grinding spiral grooves. So as to further improve the quality and productivity of tool grinding.
Another research method pursued by the International Academy of engineers is about the development of ceramic end mills and their behavior analysis in the process of CFRP milling. According to the results proposed, it is possible to assume that the developed milling cutters have high potential as an economic substitute for the conventional CFRP milling cutters, such as the coated carbide end mill.
