Surfacing 6061 Aluminum with a Fly Cutter - Tormach CNC

Good!!!!!!!!

Just a response to Bartjooh's comment about the y axis not mattering. It does! Depending on the direction of your workpiece travel, one axis out of alignment will give you stairsteps, the other axis out of alignment cuts nice troughs. The extreme example is to crank the head over about 45 degrees and cut nice troughs. Its also fun to cut nice "V" grooves in the stairstep mode. "V" grooves require two head adjustments, of course.

I'm not big on the single point fly cutters. They don't seem to cut as well as a multi-point.

The surface is not nececarily perfectly flat after that last cut. Because it seems your 'fly cutter' is not precisely square angle to the X-axis guide (Y-axix doesn't matter to it)

Just something to take in notice...

When you gonna switch to ISO standard?

Could you show how to get the best finish using the fly cutter. I know you showed a mirror finish at the end of the video but I am looking for video of what your fly cutter tools looks like (ie if you did any grinding on it) and how you got a perfect finish (ie Feed rate, speed rate, etc.)

Were you off in space for the previous five minutes of the video?

[DarkPhalanx]

To be perfectly honest, that is not a "mirror" finish. It's as good as you will get using a carbide tool. If you are looking for a "mirror" or "optical" finish, you will only be able to achieve it using a single crystal diamond tool (not a PCD tool). You can verify this by checking with companies that diamond-turn mirrors for lasers, defense-related industries, etc.

Why would one use a flycutter in this application instead of a face mill? Or is this just to show what you can use when a face mill is not available

Very informative! Thanks for posting!

[polarbear60]

This is so hot!

[silver760]

The last cut is the way it SHOULD be done,I dont know what the aim of the previous cuts were?To show you how NOT to do it??

[tormachllc]

A fly cutter is not limited to creating nice surface finishes. It is legitimate to use a fly cutter for bulk stock remove, particularly when a conventional face mill is not available. Never the less, the videos we post are educational in nature. Sometimes we try to show best practice, other times we try to show a range of operating parameters and the results, both good and bad. This helps new users understand the dynamics of machining and the consequences of speeds, feeds, et cetera.

I have a bunch of scars from a fly cutters on a manual mill!

[kawasakikillerr]

seriously, they kill!
