The main objective of this research work is to investigate size effects by down scaling the twist drilling process into the micro range (drill diameter: d = 50μm – 1mm). Therefore, experimental micro drilling tests in ferritic-pearlitic carbon steel C45 are performed with different cutting parameters and compared with data obtained from conventional drilling. Based on the concept of a representative...
The main objective of this research work is to investigate size effects by downscaling the twist drilling process into the micro range (diameter: d = 50 μm to 1 mm). Therefore, experimental micro drilling tests in steel AISI 1045 (normalized and full-annealed) are performed with different cutting conditions (drill diameter, feed, cutting speed) and compared with data obtained from conventional drilling...
