I finally found time to finish this piece I started some time ago . My intention , as in all parts I’m doing was trying different techniques by increasingly complex parts. In this case , the idea was to practice flipping a piece, and check back after turning that I was able to finish machining preserving the origins and squaring the two halves properly. Let’s see how it went :
First, I had to re-anchor the middle piece finished in the correct position. Supported by two points , as it was before, but rotated 180 º. First problem I checked , the piece YA is not resting on the ground , and now there is a degree of freedom , rotation about the axis of the screw . Anyway, I’m learning. Solution simple , put a block of wood , which happily average just enough to prevent this movement.
Secondly, make zero again with respect to the workpiece , which I did thoroughly , and checking that if I move the tool corresponding units , I can walk the perimeter of the part accurately. Once done, proceed to the first roughing :
The result is as expected, at least with respect to the 3D model. But to have it finished, would have to make two more phases, the side, as the detail of the ears and around the side, obviously can not be done with a 3-axis. Be an operation that already Carries out later.
As seen in the photos, it has not been bad, for the first time this type of complexity is performed. We have learned quite a few interesting details, so when something like repeat, do not make the same mistakes.
