Computer-aided economic optimization of end-milling operations

Article Abstract:

Computer-aided optimization strategy for the process planning of machining operations provides an optimum solution to problems involving computer numerically controlled machine tools. It is also an important tool in the selection and design of milling machines for economic machining. A simulation application demonstrated the efficacy of the approach under several constraints, such as machine tool feed force, torque, power, and component surface roughness.

Tardiness minimization on parallel machines

Article Abstract:

A branch and bound algorithm was formulated to address the problem of scheduling jobs on identical parallel machines. The algorithm specifically tries to lessen the overall tardiness in the scheduling problem by integrating the properties of an optimal schedule with an efficient lower bounding scheme. Optimal solutions were derived by the algorithm within acceptable times for problems with up to 15 jobs.
