Not having existing drawings or CAD for the seen part, it is targeted and prepared for point collection to begin the reverse engineering process.
The part is scanned and millions of points are collected. They are then recomputed and made into a STL file.
Die pulls established
Rough casting cad created
Rough casting is developed without milling allowing maximum amount of material required for casting to be calculated.
Die pull is optimized and set from the scan data and features developed following these set vectors. This particular casting required 6 axis of pull.
Casting pins & inserts are created
Machining tool solids created for milling purposes
Machining tools/solids created for the milling process of the casting.
Casting inserts are created for downstream milling and reduction in material use.
Threads are measured and documented in the cad model
Draft/slope is checked and verified
Threads are gauged and added to the machined casting where necessary.
Each die vector axis is checked to verify that the draft meets tooling requirements for its direction of pull. (Checked to the seen arrow in the image.)
Final complete CAD Model
Scan data compared to cad
The final part developed from the STL file goes through a clean-up process and is ready for delivery.
The final CAD model is overlaid with the scan data file for a final visual check.
Dimensional call outs
Key features of the CAD part are measured and compared to the original scan for deviations in the part.
Dimensional checks can be made to verify positions of center lines and key features to mating components.
The CAD developed is constructed to properly fit to mating components and fit & finish is verified.
