NC verification has been widely used in milling and turning machining, but the implementation of NC verification for wire electrical discharge machine (wire EDM) has received little attention, made difficult by the characteristics of geometry cut by

Computer modelling and simulation technology assists in validating NC (numerical control) programs before they are executed on a computer-controlled machine tool. This technique is known as NC verification. The speed and the accuracy of NC verificati

Speed and accuracy are important criterion for evaluating any NC verification system. The speed must be much faster (preferably by orders of magnitude) than physical machining. The accuracy must meet shop floor usage. Extension of an NC verification

Open architecture controls provide operators much more flexibility and ease in making modifications at the control. Virtual CNC machining, or verification, at the control provides a layer of safety as well as added functionality. The operator can rep

The atomic structure of a 〈110〉 screw dislocation core in aluminum is calculated by the modified lattice‐statics method developed in the preceding paper. The method includes anharmonic as well as harmonic forces and permits relaxation of the at

The problem of the stability of a three‐dimensional crack will be analyzed within a lattice‐statics approximation. Hsieh and Thomson employed a similar approach for a two‐dimensional crack. In that work the force was taken to be linear up to an

A modified lattice‐statics method to calculate the atomic displacements associated with a screw dislocation is outlined. The model incorporates an anharmonic region wherein the forces are derived from a pair potential. Appropriate energy and force

The atomic limit of the Hubbard Hamiltonian is extremely degenerate. The ground-state degeneracy, in particular, makes the zero-temperature Green's function for this limit ambiguous. The manifestations of the degeneracy in the one- and two-particle G
