TL;DR: In this paper, the material flow behavior during friction stir channeling (FSC) is studied and the magnitude and direction of the net forces acting on the tool are analyzed to understand material flow behaviour and the occurrence of channels in the nugget.

TL;DR: In this article, an observational study of the process forces associated with bead-on-plate runs on two aluminium alloys, 6061 and F357, was conducted and the dependence of the nugget width with various heat indices was evaluated.

TL;DR: Friction stir channeling (FSC) is a simple and innovative technique of manufacturing heat exchangers by creating continuous, integral channels in a monolithic plate in a single pass as mentioned in this paper.

TL;DR: In this paper, a mechanistic model for the process specific energy as a function of the processing parameters during friction stir channeling in Al6061-T6 was developed and investigated.

Abstract: A milling tool (309) includes a cutting insert (328, 329) coupled to a movable blade (322, 323). The movable blade may change from a retracted to an expanded state to engage and cut downhole casing (203). A cutout initiation region of the movable blade makes contact with the downhole casing, and cutting inserts with turning portions designed to cut in a turning manner may be located in the cutout initiation region. Cutting inserts with milling portions designed to cut in a face-milling manner may be located outside the cutout initiation region. Some cutting inserts may include both turning portions and milling portions.
