Laser Cladding & DED Track Overlap Calculator
Compute single clad bead width ($W$), layer height ($H$), hatch stepover pitch ($P$), track overlap percentage, specific energy input ($E$), and surface waviness.

DED Toolpath & Vector Prepress Notes
1. Overlap Optimization: If overlap is $< 40\%$, deep inter-track valleys occur, trapping un-melted powder or gas bubbles. If overlap $> 60\%$, excessive heat accumulation causes unconstrained bead height buildup and melt pool slumping.
2. End Turn-Around Fillets: Continuous serpentine CAM toolpaths must include smooth tangential turn-around radii ($R \ge W/2$) to prevent CNC deceleration dwell at the track perimeter.
