Multiobjective Optimization of Cutting Parameters for TA10 Alloy Deep-Hole Drilling [PDF]
Materials, 2022 In order to obtain better quality TA10 pipes, the Boring and Trepanning Association (BTA) deep-hole drilling process is used. However, this type of machining leads to difficult chip removal, tool wear, and poor hole-surface quality. In this study, a deep-

Tool stability analysis for deep hole drilling [PDF]
MATEC Web of Conferences, 2018 A large number of parts have deep holes, therefore, rotary cutting tools, which represent relatively long and thin columns are used for holemaking. In this article we analyze the behavior of such tools under the influence of an axial compression load, in our case, the axial cutting force F p ,
