Thanks Pilot82.

Now, I'm working on a steel mold to made some pilot figures of foam. This material It is super light and very durable.

I will try to post a 3D picture of my pilot bust !

I thought about doing a mold for pilots but you need a bunch of molds to cover all the sizes so I just cut the foam pilot on the cnc mill, you can resize it easy on the mill !

Do you have a 3D file to share from your pilot model ?

Thanks !

This is a Helmet head pilot that I digitized using a .25 dia. probe making .050 step over, HelmetHead1 is the front side and HelmetHead2 is the back side feed rate is 60 inches a min. so use this to cut foam and you will need a long .250 dia. 2 fluted ball nose end mill if you cut something besides foam change the feed rate but in foam you could cut it faster if you wanted, at 60 it will take about 20 min. to cut each side, this is a 40% size pilot and you can resize it up or down, load this g-code program into your machine and then you can graph it to see what it will look like. I have cut a few of these and I might start selling them if I can find time to make them, tell me what you think about it.

You will need a block of foam 5.5 thick(top to bottom) 8 inches in X (right to left) and 9.5 in Y (in and out) I mount the block of foam to a indexing fixture it will not hurt if your foam block it longer so your cutter will not run into your indexing fixture in X so make it 8.5 long zero Y in middle of block or CL of indexing fixture zero X at left edge of foam block and zero Z so center of ball end mill is on center of indexing fixture and move up 2.75 in Z and zero again because z will move down from Z zero 2.75 and then move Y axis and Z will move up as it cuts in Y if you under stand me if not ask and I'll try to give a better explanation.

[McFueler]

Well I did a reversal on that file so it will be like a mold or female cut not a male cut so try this file I changed it to be like it was supposed to be, sorry about that don't run that other file run this one.

[McFueler]

I noticed all the Z moves were positive and they were supposed to be negative !

[RicardoTJ]

I will try to run this on my CNC this weekend , and post the results.

Thanks Fueler !

I wonder if you have a 3d model file like a solid figure...

It is little risky, since the Z axes will go down to Z-2.5 in the first steps of the program.

But Now Im thinking in transforming this data into a 3D model.

NOw I have bunch of work, but this is something that I will definitly going to do in the near future.

Regards !

This is a digtized file off the CNC mill I have here at work in order to make it a file you could open or do something with like load in you machine I made it into a txt file, and I do not have that in a 3D Cad file, sorry. Be sure to dry run it so you will know what it is going to do, but all it is doing is running the same path the probe ran when it measured the part.

A helmet head should be easy enough to model in SolidEdge or SolidWorks.
