Lead and Lean on an A/C trunnion

Fusion's Lead and Lean angles live in a frame attached to the surface and the direction of travel. The machine only has A and C. Watch both.

Multi-Axis

Machining Type5-axis

Primary ModeLead and Lean

Lead Angle15°

Lean Angle0°

Positive Lead tilts the tool forward along the direction of travel; negative Lead is lag. Lean tilts it sideways. Both are measured from the surface normal, Lead first, then Lean.
