Abstract: A method for configuring a fixture for use in machining of sequential parts via a machine tool, for a planned machining movement of the machining element, uses a model of the part and fixture. Respective reaction forces at the plurality of part contact references are computed. Responsive to computation of a negative reaction force at a said part contact reference, a modification is made to a machining parameter.

Abstract: Feed rate scheduling methods include measuring a topography of a grinding wheel of a machine tool, calculating a topography parameter using the topography, and calculating a feed rate scheduling parameter for a toolpath of the grinding wheel based on the topography parameter. The topography may be measured using microscopy. The topography parameter may include a plurality of parameters including a density of crystals at a given depth (C(h)) of the grinding wheel and/or an area fraction of crystals protruding at a given depth (?(h)) of the grinding wheel. The feed rate scheduling parameter may include a grinding wheel feed rate, a grinding wheel spin rate, and/or a grinding wheel cutting depth, among other parameters.

Abstract: Systems and methods for mesh refinement of finite element analysis simulations employ an analytical modeling program configured to identify a location of contact between two components and a finite element analysis program configured to use the identified location to perform finite element mesh refinement. In this regard, the location of contact (and location of desired mesh refinement) is identified using analytical modeling. Said location of contact is then provided to the finite element analysis program for determining precisely where to perform mesh refinement on the finite element mesh. The finite element analysis program performs a mesh refinement at the exact location of contact between two components to provide for optimized and more efficient finite element analysis.

Abstract: A feed rate scheduling method may comprise: receiving an engagement geometry of a subtractive component for use in a computer numerical control (CNC) machining process; receiving a tool path for forming a component from a workpiece via the CNC machining process; calculating a plurality of bending moments of a spindle at various intervals along the tool path; and determining a feed rate schedule for the tool path of the subtractive component based on the plurality of bending moment.
