Highlights

?A procedure for subtracting geometry from a cubical shape grain structure model is developed.

?The procedure consists of voxel-based grain structure creation, Boolean operations, and meshing.

?Explicit grain structure FE models of a micro-pillar and a micro-tube are presented.

?The procedure facilitates making multiple cuts while attaining FE model state of equilibrium.

?Distortion during and after machining of an Inconel 718 aircraft engine disk is simulated.
