High Feed machining (using Iskar Eff 6mm mill )

[Teh Bear without Brains kinda idiot]

Hi ,Folx!

Sometimes due to the part geometry High feed suites better than High speed tp.

 So I`ve tried Iskar EFF MILL  on H13 with big success .

Depth of cut 0.3 mm s6500 rpm F4000 mm/min  length of tool z-35mm in shrink Mastercam X7sp2 .

I used surface high speed area clearance toolpath .

Do you have experience with High feed milling (little depth of cut big feed ) and what toolpathes do you use to run it .

I will appreciate every advice .

Best regards

I would use dynamic core and peel mill... if I were using x7.

 

However, I usually am doing little stepover, full flute stepdown.

~~~~~~~~~~~~~

This was 3 axis toolpath

Dynamic core and peel mill 2 axis tp

Me usually too .

But when your bottom looks like lunar nightmare (extrusion molds specific)I had found out that feed mill is faster

At least two times

I've been cutting a lot of extrusion dies using Seco high feed indexible mills with Surface High Speed Area Clearance, Surface High Speed Rest Rough, Waterline, And Surface High Speed Waterline Rest. I tried the full tool engagement dynamic tool paths on some molds, but the high feed paths work better for me. Might have something to do with using 40 taper Haas mills. The Seco mills run great in H13 at 900 SFPM .025" depth of cut, and .025" per tooth feed.

Iscar Feedmills are great tools

I use them with high feed toolpaths with great results

50% radial step over .05" step down, .025 to .05 feed per tooth.

RPM and federated is dependent on the machine.

I've yet to find a machine that can deliver all these tools can take.

I do it all the time.  Our main family of parts have several closely spaced shallow ribs, and I use Widin 6mm, 4mm, and 3mm high feed cutters with .5mm radii.  We cut these features after heat treat, so RC46.

Walter feed mills also work great they may hate surface footage but they do love (handle) surface footage.......

70 percent step over, light depth of cut. If its something that I want full control over, I will do 2d contours for 90 arc entry/exits . Most of the time core/ opticore if I am working with models.

Thank you guys for the info
