CNC Feeds and Speeds
Feeds and Speed Suggestions for AvidCNC PRO Series CNC Routers
DISCLAIMER: These feeds and speeds are merely suggestions. Ideal feedrates can vary between tooling manufactures, material, and even vary within a single piece of material. We are not responsible for broken tooling, failed projects or machine damage.
Chipload: Chipload can be an indicator of cut quality. Chipload is measured in "feed per tooth", as in how far the cutting tool moves per cut it takes from your material. Too low of a chipload can result in burning and find dust which generates heat that can result in shortened tool life and even tool breakage. Too high can result in chattering, tear out, and in extreme cases tool breakage. Chipload does NOT account for depth of cut, but as a general rule a chipload of around .005 feed per tooth is a good starting point for carbide tooling on our AvidCNC routers. A reliable chipload calculator can be found here.
Depth of Cut: As a rule, it's recommended to start at a cut depth no more than the diameter of your cutter's shank. A 1/4" upcut bit should start at a cut depth of 1/4". You can increase this cut depth as you become more familiar with the tool and its capabilities. Note that some tooling, like compression cutters, often have a minimum cut depth to function properly. Please check tool manufacturer specifications for more information.
