Like the previous simulation in this series, this machining simulation provided by Boeing Research and Technology (using CGTech software) shows roughing followed by material removal from the corners prior to finishing. The finishing of the walls is performed with fast passes at successive layers.
This simulation also shows finishing of the floor of the pocket. Note how the tool radiates out from the center of the pocket to the wall. This keeps unmachined stock always adjacent to the cut for support. No section of the floor is ever touched again after it has been machined once.
