Adaptive Clearing - what type of end mill?

I'm sorry if this is a stupid question, or has already been asked but I couldn't find it when I searched.

 

Does Adaptive Clearing expect a roughing end mill to be used, or can a general purpose be used with the default settings?

 

 

I realize if I back off on some settings I could probably make it work with anything, but I'm curious what it was intended for?

It doesn't expect anything, as the speeds and feeds will need to be calculated for your cut parameters and tooling.

 

As an example I use a 1/2" four flute variable helix end mill up to 1.5*Ø, 10% radial cut at 8000 RPM and 168 IPM in mild steels, and that's fairly conservative. Feedrates can go as high as 240 IPM with no ill effects, and that is a general purpose AlTiN coated end mill.

 

If you want a good calculator for HSM toolpaths I highly recommend HSMAdvisor: https://hsmadvisor.com/

 

Very satisfied customer is all, I have no relation to the company.

Thank you for taking the time to respond.

 

 

I'm working on getting approval for HSMAdvisor, thank you for recommending it.

 

I've been using a slide chart and recommended feeds and speeds from the end mill manufacturer, but it's kind of limited.  Horsepower has also been a concern of mine with larger mills.

 

 

I was concerned about the type of mill with Adaptive because of how it uses the tool.  I'm still very new to all of this.

We were all new at some point, so no worries there.

 

Make sure to set up a machine profile (for each machine model) in HSMAdvisor, the default one for the Haas 12k direct drive spindle has been spot on, but I did set one up for our Fadal that works pretty well. This will help you fine tune actual load using the torque curve of your machine(s) and I have found it very useful.

 

Those charts are handy starting points but obviously conditions can vary drastically between machines. A Brother Speedio won't take the cut that an OKK can and the charts are rarely good for that sort of difference.

This is a bit off topic but, how do I find out our machine's max torque?

I'm guessing taking 7.5HP, multiplying by 5252 and dividing by the max rpm of 5000 isn't going to work?  That gives me 7.8 ft/lb but I don't know if it's the proper way to go about it.

That's the formula typically used to calculate HP of gasoline engines reversed.  Not sure if it applies to electric motors.

Most machines have a torque curve and the maximum is usually only at a specific RPM. Machines like the Okuma M560V though that have a double-wound spindle motor can have very large high-torque ranges. The best way is to get it from your machinery manufacturer or vendor.
