This machine is so bad it's painful to watching

Casting machine ka lock tut gaya hai to repair hota hai

How would you set up to cut a box 15 x 5 in the center of a piece of material size 19 x 7? I tried different x and y positions but I couldn't hit it in the position I wanted to cut. Always off the mark I want.

Just found your channel and Subscribed. Very nice work

An interesting project. Thanks for the video. And now on to the suggestions. I would have at the outset shown the finished item, so that your viewers knew where you were going. This could have been done by sticking the finished ring on your finger and showing the inner ring spinning, sort of like a fidget toy. Second, if you have a way to color either the inner or outer ring, then I would do do. There are lots of products on the market that will turn aluminum black, so doing that to one of the parts would be nice. Finally, I would work on your audio, the level is too low.

This was disturbing to watch ... intermittent hand held camera shots, occasional fast forward video, workbench where stuff tends to roll of the table surface and the general ambience of distraction and chaos.
