TOOTHBRUSH
 

 

The client was developing a power toothbrush with some unique attributes.  They wanted to

machine some features into the surface of the brush head.   The prototype heads were being

injection molded in short run epoxy tooling.  The problem was that,  in addition to shrinkage, 

the machined master brush had been modified,  by hand,  from the original CAD.  New

surface data was needed to machine the desired features on the prototype parts.  Surface

and contour scans of one of the molded parts were done from  3   postions.  From this,  new

surfaces were developed to allow the machining to proceed.

Client :   Zephyr  Design,   Alameda,   CA
