We also have some pretty cool film props that also have an NDA, so I'll post them later as well.
In the mean time, I thought I would do a helpful post on slicing 3d models, and getting the cnc to clean up the glue joints.
There are a million reasons why you would want to slice some model parts on the router.
One of the biggest for us, is that we are sometimes limited by available cutter lengths or material thicknesses.
For example, when were cutting a model over 3.5" thick, but the available material only comes in 2".
One way is to have Aspire slice the model, machine the parts separately, then glue them up. But then the seams require work to clean-up after. I much prefer letting our Techno do as much work as possible, because it does it faster and better than I ever could!
HDU material is exactly 2" thick. I also have a piece of 1" material I can use as well. I could glue them together into a 3" thick slab, but the other problem I have is that my 1/4" ballnose cutter is only 2.5" long. So after it's slid into the collet, I only have a total of 2" of cutter length available! I certainly can't do it all in one shot...........or can I? (dun, dun, dun) That was cliffhanger music you just hummed..............
First thing up is to slice the model into layers I can use.
At this point, it is important to add some small tabs to hold the model in place for the second layer machining. I simply drew some rectangles, and made the .250" thick. Make sure to set the tabs to "MERGE" or they'll pop out the model, looking weird. This should hold it while it cuts.
Tomorrow I'll cover the rest of the process...........
