what would be the best strategy to machine these cooling grooves in one pass?

Hello. I have a question about machining a cooling groove with a milling cutter of the same diameter. What machining strategy will allow me to machine this groove (attached in the screenshot) in a single pass and make the cutter enter the material beyond the stock material? Currently, I have managed to achieve a result close to the intended one using the "flat" strategy. Unfortunately, the cutter enters straight into the material in Z axis, and to machine the groove in the narrowest part (2mm), I had to specify its diameter as 1.98mm, causing the cutter to make two passes to finish both sides. Thank you for your help. Regards.

The file you shared doesn't contain any toolpaths, so it's a bit of a guess as to what you've tried.

Are you referring to the small circular grooves, or all of them?

I'm sorry, it seems I forgot to save the file. Now the file should contain toolpaths.

Okay, but which grooves are you looking at machining with the same-size tool?

I was thinking about machining all of them with one tool (2mm endmill) and one strategy if possible and groove number one is the narrowest one.
