Shih This research investigates the strategy to achieve high material removal rate in tool path planning for the near-dry electrical discharge machining (EDM) milling process using tubular electrode with a lead angle. The proposed strategy to prevent leakage...

... less research in which geometric parameter (tool path, tool orientation, workpiece setup, etc.) planning and kinematical/dynamical parameter (feed rate, cutting depth, cutting force, etc.) planning are concerned simultaneously. Kim and Sarma ( 24 ) classified multi-axis tool path planning as one...

.... A computer simulation based path-planning strategy was developed, which predicts the optimal locations of discrete packet depositions within a mold in order to obtain a uniform reinforcement distribution. Two optical tools, one for measurement of fiber orientation and mass distribution and one for height...

... method developed in this study provides, therefore, an enhanced methodology for path planning in high-speed, high-precision micromilling operations. For both geometries, interpolation by NURBS results in a single segment the length of the entire tool path while circular interpolation results in a large...

... engagement that limit production rates, increase tool wear, and reduce part quality. Tool-path planning has been traditionally approached from a purely geometric perspective. The vast majority of bulk material removal occurs in 2.5 D roughing operations. For such operations, tool-path trajectories...

.... This paper analyzes the properties of the swept profile of a general cutter in five-axis tool-end machining. The relation of the swept profile, the part geometry, the tool motion, and the machining errors is developed. Therefore, the error sources can be detected early and prevented during tool path planning...

...Zezhong C. Chen; Geoffrey W. Vickers; Zuomin Dong Three-axis CNC milling is often used to machine sculptured parts. Due to the complex surface shape of these parts, well-planned tool paths can significantly increase the machining efficiency. In this work a new principle of CNC tool path planning...
