Here is my next approach to this problem. I was able to reduce the milling time to 39 minutes (2 pieces). I still see the possibility of further g-code optimization. Some of the bit movements seem unnecessary. In the first attempt, I wanted to minimize the number of paths. As a result, I created a lot of open paths, and that was a mistake. I noticed that it is better to leave the paths closed because no time is wasted on moving the cutter back and forth. I attach also the picture of the bit I used.
