Another part made yesterday... With some fails, learning and redo better...
I needed to finish the motor pod, with the rear part... A bit of planification, and I decided that the chamfer will be done within what I think could give the best result : a pocket with a flat end milling bit.
Therefore my work started with two supports I'll use later on...
Then I did used a 10mm aluminium stock reduced to 8mm using a pocket and a contour to get my starting point... On which I engraved a logo
Then, next step was to drill and thread the two side of the part... spoiler : I did this wrong at first, and I had to adjust the method after the second part to get it right.
First method was wrong as the part was not fixed strongly enough
Second method was wrong as the part was fixed but the 0 derived from anchor position and thickness of the material was off.
I reapply the same way for the 3rd part, and set the origin right with the manual probe. Lesson learned : when precision is required do not assume work origin postion from a derived position.
Next, I fixed the part in the defined support for the last operation and did a 2.5mm pocket where position was less important because I applied an offset to the contour of the pocket...
And here is where we are now...
At the end, CNC machining requires precision and proper planing. Clearly, trying to go too fast is not going to help : taking time to make sure the part is rightly positioned and the origin set properly is definitely the most important thing...
