Speeds and Feeds

Postby jschrempp » Tue Feb 24, 2015 12:42 am

WIkipedia has a good page on speeds and feeds. In particular, you can get the cutting speeds for many materials using a high speed steel cutter.

http://en.wikipedia.org/wiki/Speeds_and_feeds

Missing from the Wikipedia table is Wood. The Cutting Speed for a soft wood, such as pine, is 1000 feet per minute.

There is a recommended speeds and feeds calculator at

http://www.custompartnet.com/calculator ... d-and-feed

The calculator needs Feed per Tooth. We were told to use the following values:

Aluminum: 1/100th the bit diameter
Wood: 1/50th the bit diameter
Foam: 0.1

Plunge speed should be about 1/3 the feed rate.
