3d milling - shopbot - high heel
Result of the high heel with the Shopbot using Partworks3d.
\
How to begin:
First thing first. Because this was the first time we (Tomas and I) tried the Shopbot in 3d mode, we didn't knew how to use it in action. We watched a tutorial. Now for the real thing.
The 3d model was made by Rosa, we tried to help here make it real.
--- Toolpaths of the Shopbot program Partworks3d is visible in the Fabmoment of Tomas ---
First align the material on a place where you easily can flip it. This is necessary due to 3d object has 2 sides that has to be milled.
Then when one side is done, you flip it over to the bottom side.
You have to place the material in the same alignment as you did at the top side.
For this milling session we used a 6,4 mm end mill bit for roughing.
And a 6,4 mm ball nose milling bit for finishing
On the topside we first did it with a step-over range of 1 mm. This was to much for finishing and the result was not that smooth.
Because you have two sides we did the bottom side with a different setting. This time with a step-over of 0,2 mm.
-- How less the step-over range how more smoother the surface --
Here on this photo you can see the difference of the step-over range. More to the left less smooth, more to the right much smoother.
_ note: because we didn't aligned the object that good, there's a difference between right and left. it was a little bit of. This is not good... :)
End result
The things what are sticking out are tabs. This can be done in Partworks3d. It's makes the object in the material steady.
Settings speed:
X,Y = 15
Z = 19
always check the speed in the Shopbot Edit. It always sets it self to X,Y= 126,5, Z=126,5
???WE DONT KNOW WHY??
MAKE SURE TO CHECK THIS, OR ELSE THE MILLING BIT EXPLODES
