If you do many similar parts from time to time, re-using an existing machining assembly with a set of toolpaths can save you a lot of time.
To create your initial machining assembly, follow these steps:
The following screenshot shows a simple example of a fully configured machining assembly:

Now, the next time you are to machine a part similar to this, you can use the assembly as a template:
If you get mating errors, it's fairly quick to use the Replace Mate Entities feature to it up to date.
Depending on how similar the geometry of your parts are, you may have to re-select some geometry and add-or remove toolpath operations. In many cases, however, simply regenerating the toolpaths is sufficient:
