AiVibeToolpath
A toolpath is the route a cutting tool's reference point follows through and around the workpiece, defined by a machining strategy, step-over, step-down, tolerance and linking moves, and output as CNC motion commands.
CAM software generates a toolpath from the part geometry, the selected tool and a strategy. Roughing strategies, such as offset, zigzag and constant-engagement adaptive paths, remove bulk material, while finishing strategies, such as contouring, parallel or raster, scallop and pencil passes, produce the final surface. Each toolpath includes cutting moves, lead-in and lead-out moves, and linking moves that retract and reposition the tool between regions.
Toolpath choice affects cycle time, tool life, surface finish and accuracy. Constant-engagement roughing keeps tool load steady and allows deeper axial cuts, rest machining removes material left by larger tools, and multi-axis toolpaths tilt the tool to reach undercuts or use shorter tools.
Step-over and tool shape determine the scallop height left on 3D surfaces; for a ball-end mill a smaller step-over leaves smaller cusps but needs more passes. Calculation tolerance controls how closely curves are approximated by short segments. Excessive air cutting, abrupt direction changes and full-width engagement in corners are common inefficiencies and failure causes, so toolpaths are reviewed and simulated before release.
Key points
- The path followed by the tool reference point, generated by CAM strategies
- Roughing removes bulk stock; finishing produces final surfaces
- Step-over and tool shape set the scallop height on 3D surfaces
- Linking moves, lead-ins and lead-outs are part of every toolpath
