Cnc router aluminum feeds and speeds.
What s the 1 reason cnc routers fail to cut aluminum.
Cnc router aluminum cutting faq can a cnc router cut aluminum.
It s a matter of using the right cutter or bit the correct feeds and speeds and avoiding various other pitfalls described in this article.
Feeds and speeds is generally used to refer to feed rate slew rate plunge rate and spindle rpm.
Materials have rated surface speeds for a given type of cutter.
When milling or drilling or creating a tool path for a cnc machine the feed rate must be determined.
Tried out a complex part in 6061 the other day.
Wanted to share the results and feeds speeds used and compare to what others have had success with.
16500 rpm 25 ipm 05 doc wd40 as lube.
I used an o flute 1 8 bit and i have the pro4896 and pap spindle from cncrp.
This works particularly well for routers.
Start off using an rpm derived for the chip load for the material being cut see charts.
An overview can be found here.
Given the diameter of the tool and the surface speed the rpms of the spindle can be calculated.
The textbook cutting speed for aluminum using a carbide tool is about 1 500 surface feet per minute at the high end and 1 000 at the lower end.
A homemade hobby router will be very different from a large router that s professionally built for aerospace composites.
The feed rate represents how fast the machine will move the router bit though the material when cutting and is critical to get right for leaving a good quality cut edge.
The five big challenges i have had with cutting aluminum various routers i have had are.
What type of aluminum.
The harder the material the slower the speed.
The speeds and feeds calculator may be employed for calculations of estimated speeds and feeds rpm and ipm values on the basis of the parameters you have currently set based on your tools and stock material.
Increase the cutting speed feed rate until the quality of the part s finish starts to decrease or the part is starting to move from hold downs.
Lack of lubrication is the 1 reason cnc routers fail to cut aluminum.
Aluminum is most often alloyed with other metals to enhance specific properties.
Most spindles the term for the router attached to your cnc router will go from about 7 000rpm to 18 000rpm.
Either way there are a few starting points that might work for you.
