This idea can save a ton of time in ineffecient toolchanges and programming:
2 examples below:
From 48 to 3 toolchanges! From 28 to 17 minutes
From 9 to 3 toolchanges!
If you nest a pattern, there is no possibility to have efficient toolchanges. It just multiplies the lower pattern and any toolchange available which lead to ineffectient toolpath and a lot of changes.
3 toolchanges 48 toolchanges
It can look something like this
And it would also be benefical for multiple parts in one sheet with patterns like this example:
9 toolchanges instead of 3
For those of you who want to play with a file, I included the first example as IPT
