Hi there folks, i need some pointers on how best to form a dish.
I have made a press tool which i thought would do the job but unfortunately it failed.
Here is a pick of the top and bottom tool, my first attempt(on the rhs) and my second attempt(lhs).
The first attempt crumpled up while forming the side walls of the dish as shown.
For the second attempt i reduced the outside diameter of the blank and it formed no problem. its just a pity the side walls are nowhere near the length i want
What am i doing wrong here? I'm guessing there's some sort of boundary involved when forming a dish with parallel side walls out of a circular plate?
Should i form the base of the dish with the press tool then try and spin the walls?
Help!
I dont have a spinning machine available but i do have cnc mills/lathes and conventional mills/lathes.
ps. im lookin to produce a couple hundred of these.
