54,193 ABSTRACT OF THE DISCLOSURE The present invention is a system that takes a drawing definition produced by a CAD/CAM system lo and produces a debugged part program. The drawing definition is used to produce a sequence of processes which will produce the part. The drawing definition is a list of the surfaces which create the part. The list is scanned by a process planner 14 and a list of primitive shapes and transition points in each shape is created. The transition points are used to create a process tree defining regions for machining. The tree is populated with region boundaries that are used to designate machining operations. The boundaries are then used to select particular processes based on the shape to be machined during the operation by traversing a shape tree looking for a match. The process selection also specifies tools, feeds and speeds necessary for rough machining the part. During process selection the size of the region is also determined and from the tool selection, the number of rough cutting passes are determined for number process. The sequence of the processes is determined by scanning the process tree and concatenating like processes and, within the like 32 54,193 processes, the processes with the same tools and preferred tool direction. A finishing process is produced by creating and scanning a continuous part surface to produce contouring cuts. An appropriate machine is selected based first on the rough stock dimensions of the stock to be used to make the part and then on the number of tools that can be held by the machine and possible feed speeds of the machine. The sequence of processes and process parameters are used by a code generator 16 to complete macrocalls corresponding to the processes. The resulting part program is transferred to a code processor 18 which produces the machine tool code for the particular machine 20 selected.
