Chip thickening in deep-hole drilling

International Journal of Machine Tools and Manufacture, 2006
In conventional turning and milling cutting process models, chips are free of external forces after leaving the cutting area. However, in a drilling process, chip flowing is constrained by the drill flute, causing the change of chip shape and drilling forces.

The Performance of Small Diameter Twist Drills in Deep-Hole Drilling

Journal of Manufacturing Science and Engineering, Transactions of the ASME, 2006
This paper investigates the performance of small diameter high-speed steel twist drills drilling boreholes with a depth of ten times the diameter into carbon steel AISI 1045 using minimum quantity lubrication. The performance of small twist drills is determined, first, by their deep-hole drilling capability, i.e., in how far the cutting forces can be ...

Cutting fluid behavior under consideration of chip formation during micro single-lip deep hole drilling of Inconel 718

International Journal of Modelling and Simulation, 2022
When micro-single-lip deep hole drilling the efficiency of the cutting fluid supply cannot be investigated experimentally due to the inaccessibility of the cutting zone. For this reason, this paper examines the cutting fluid behavior, taking into account
