Grahic Jump Location
Finding tool accessibility: (a) Shrink outer contour and grow island contour by a distance equal to tool radius (b) Subtract grown island contours from shrunk outer contour (c) grow the result by radius of the tool
Grahic Jump Location
Decomposing pocket: (a) Tool accessibility of larger tool in tool pair (b) Tool accessibility of smaller tool in tool pair (c) Region to be machined by smaller tool in tool pair is given by the boolean difference of the tool accessibility of smaller tool and tool accessibility of the larger tool

Directed acyclic graph for 4 tools
Grahic Jump Location
Test parts made by CyberCut pipeline. Times are in minutes and a hourly rate of $29.00 was used for cost calculation
Grahic Jump Location
Comparison between Generative Machining of (a) typical CAD/CAM tools and (b) CyberCut. Cybercut’s automated process planning requires less human interaction, resulting a great saving in process planning time
