5-Axis Porting

5-Axis Porting is an addition to GibbsCAM 5-Axis Milling, optimized to simplify machining ports, manifolds, throttle bodies and any tubular openings that change shape and curvature from end to end. The specialized interface is condensed to use only the settings needed for porting operations, making programming much easier and faster. Machining strategies include roughing, rest roughing, and spiral and plunge-along finishing. To control excessive machine motion, 5-Axis Porting uses 3-axis machining as far into the port as possible, and then automatically transitions to full 5-axis to allow for maximum tool reach. All 5-axis motion is calculated for smooth and gouge-free toolpaths. Tool tilting is automatic, at optimal angles, with no need to split surfaces or create tool axis control splines. The software can automatically detect the spine curve through the port and properly align the toolpath. The upper and lower sections of the port can be determined automatically, using maximum tool reach, at the midpoint, or by a user-specified percent of reach, always ensuring proper toolpath blending between upper and lower sections. Overall, 5-Axis Porting makes programming easier and faster, and generates a cleaner, more efficient toolpath for faster and higher quality machining.
