Conventional tool-path generation strategies are readily available to generate geometrically feasible trajectories. Such approaches seldom take into consideration physical process concerns or dynamic system limitations. In the present work, an approach for improving a geometrically feasible tool-path trajectory based on quantifiable process metrics is developed. Two specific measures of toolpath quality are incorporated into the iterative improvement algorithm: instantaneous path curvature and instantaneous cutter engagement. These metrics are motivated by a desire to minimize acceleration requirements and maintain a stable steady-state cutting process during high-speed machining. The algorithm has been implemented for two-dimensional contiguous end-milling operations with flat end-mills, and case studies are presented to illustrate the approach.
