Speeds and Feeds on the M4

Now that people have started cutting on their M4s I thought it would useful to share recipes that have worked or failed.

I have very little experience with wood working and have never used a router in wood, my only experience has been with carbon composites. :sweat_smile:

My first cuts were in 18mm MDF where I used 1500mm/min , 6mm DoC using a 6.4mm straight cut two flute router bit because thats what the local hardware store had in stock. I cranked up the RPM on the router as it “sounded” better while cutting.

Whats worked or hasn’t worked for you?

The key is that you want to be getting chips, not dust.

When you are just getting dust, the bit is spending a lot of time rubbing
against the workpiece, and heat destroys bits.

There is a much more in-depth discussion on the topic a month or so ago
(presented by someone with a lot more knowlege than I have)

However, with the caveat that I think MDF will only ever make dust since it is really just pressed dust. :slight_smile:
