Lasers have material tests. An array of squares producing results for different power using a given speed.
Is there something comparable with cnc?
Hi
Most tool bit manufactures supply feeds and speeds often known as recipes
I use these as a base point and work from them different planks of the same wood can machine very differently. Along with how ridgid the machine is the z axis set up and how secure the project is
Tool life and surface finish are also factors to be thrown into the mix
I tend to adjust spindle speed on the fly as i have a spindle and cant adjust the feed rate on the BB controller this gives a different chip load on the tool and is really a work around
Your ears and eyes will be the best indicator of the right speed and feed.
If you decide to change anything in the speeds and feeds including depth of cut plunge rate stepover always only change one parameter at a time and keep a record of the changes
When I first installed my Onefinity i spent a good day just working out what it was capable of my machine earns its keep in a manufacturing workshop, I use 6 tools to cover pretty much all of my needs on 2 different types of wood I have my feeds and speeds set in a custom tool library in Carveco Maker
I have no doubt you will break a few cutters, I did and still do on the rare occasion, try a few different brands until you find a balance of brand and price once you do I would suggest you stick to them as its controlling another variable
Good luck
Drop me a message if you have any specific questions

I too have always wanted a “Benchy” (a 3D printer benchmark model) for CNC. I’ve just never been sure what could possibly be the most universally acceptable vectors to accommodate this desire. I’d like to say that there are simply too many variables, including types of toolpaths, bits, and materials, to make anything practical. However, the aforementioned 3D printer test has to deal with many variables like printer, nozzle, filament, etc., and is widely accepted and used.
