A 4- or 5-axis machine can take longer to orient its rotary axis versus its linear axis. To reduce the overall cycle time when drilling a part with holes at different angles, the Bias Rotary vs. Linear 4/5 Axis Positioning option controls whether the system will drill the hole with the closest vector versus the next closest hole. Combine this option with the Reverse Direction option to further reduce travel time.
When this option is checked, the system drills the next hole with the closest vector to reduce rotary positioning moves. When unchecked, the system drills the next closest hole.
