There is more than one way to skin a cat!
Previously i have showed how to machine multiple pieces out of a flat plate holding only on to 0.010" thick material on the outside of the part. (here)
But there is more than one way to do it.
Sometimes your part is so hard to hold, that using tabs or skin is the best, or even the only way of machining something.
Very often, working in prototyping, I have to make only one single part and designing and producing special fixturing is also not feasible.
Here is how you can easily machine a difficult-to-hold part from both sides without using a separate fixture:
Setup: Put or part in vise. Make sure to square off at least two sides contacting the jaws for accurate positioning and minimum distortion.
Program part normally. Perform as many operations on the first side as possible.
When machining outside profile, machine to the exact depth of your part.
Here is how your part might look after completing the first OP:Read More
