Benefits and Description
High speed machining performances are enhanced through the use of spline-based NURBS (nonuniform rational B-splines) tool path output. The output machines directly to the desired shape, eliminating additional processing steps before machining. The tool path is smoothened to keep C2 continuity wherever possible and to minimize curvature changes.
The NURBS output is controlled by the NC parameter OUTPUT_3D_NURBS available for surface milling (3- and 5-axis), finishing, trajectory milling (3- and 5-axis), swarf milling, profile milling (3- and 5-axis), volume milling, roughing, reroughing, local milling, face milling, pocket milling, and corner machining.
Pro/NC-GPOST is used to output specific syntax for Siemens, Fanuc, Heidenhain, and Maho.
