3D AutoCad DWG to suit CAM Programmer

[elwoodbeauchamp]

G'day Mates and Friends,

I have a question concerning how I should draw/section/dimention/annotate, etc. drawings of complex 3D shaped parts in order that the CNC Milling Center Programmer will not be troubled with insufficient data or views of the project.

I have individual parts on their own drawing and they pose no problem. But, the bulk of the item is somewhat barrel-shaped with an array of similar "veins" parallel to the center axis starting small at the ends and expanding toward the middle. The entire profile from end-to-end is identical, only scaled to create the "small" to the "large" viens.

I have the "barrel" designed as "Upper" and "Lower" mirrored halves.

I have experience in basic 2D CNC Machining, and Turning as well as programming. I do know 3D requires quite a number of data points on complex shapes, scaled identical profile or not, to create a decent cad drawing file for the CAM engine to secessfully create the item that is represented in the CAD drawing File.

I cannot divulge any more details of the what or how the item will be used or for what...sorry.

For a drawing of a coconut with several bananas fitted around it(bananas being small at each end and larger in the middle) how much detail should I concern myself with as to the data profile of the bananas from small to large sections?

Remember, I'm mirroring the one end for the other end...

I am sure I am making this to be much more complaced than it is.

I just want to have all my ducks/bananas, etc. in a row for the poor chap machining this thing. (It likely will be done in AU)

Thanks for your advice, and Cheers fellow Chip Makers.
