Abstract

The chapter delves into the critical role of fine drilling in aerospace engine injection plates, emphasizing the significance of understanding the mechanical properties of cutting. It discusses the similarities and differences between fine drilling and conventional drilling, highlighting the impact of size effect, cutting edge radius, and minimum cutting thickness on the cutting process. The authors present a detailed mechanical model based on time, analyzing the contact force of each part of the drill tip and its relationship with tool wear. Experimental data is used to validate the model, demonstrating the influence of feed rate on thrust values and contact coefficients. The chapter concludes with practical recommendations for designing fine drills to minimize tool wear and improve cutting performance.
