Lots of guys simply go with 1000 SFM to calculate their RPM. If you do this, you're really not going any faster than everyone else. To be honest, this is usually is what's recommended for most cutters. 1000-1500 SFM is a totally normal speed to run your spindle at.

Do you need coolant when cutting aluminum?
In the CNC machining process, cooling is essential. If you do aluminum machining without any coolant and lubricant, various problems may interfere with processing and affect product quality. In order to ensure successful processing, a suitable aluminum cutting fluid is required.5 Jul 2021
Is aluminum easy to cut?
250” and above.) Many do-it-yourself projects, such as metal fabrication, siding, or roofing, use aluminum sheet because it is a relatively soft metal and thinner gauges can easily be cut.21 Dec 2019

What is the SFM for 6061 aluminum?
800-1500 SFM
Can Aluminium 6061 be machined?
Unlike other aluminum alloys, 6061 has a high corrosion resistance. Aluminum 6061 has a machining cost factor of 0.8 when compared to steel 12L14. It can be forged, hot worked, and readily welded, as well as heat treated, annealed, and aged. It anodizes well and provides a bright, colorful finish.
Can you CNC 6061 aluminum?
This is because of its good toughness, medium and high strength, excellent corrosion resistance on harsh condition, cool anodization, and bending workability. Aluminum 6061 is commonly used for 5 axis CNC machining. This alloy also better in corrosion resistance.22 Feb 2019
What is a good chip load?
The manufacturer of the bit recommends a chip load of 3 percent of the tool diameter as a conservative starting point for testing. So, the initial chip load will be . 00069”, which is 3 percent of . 023”.12 Aug 2020
