tricordial slot milling?

[neurosis]

Im machining a very deep slot in some parts. Actually its more of a clevis. I would like to try to rough this slot out using tricordial (spelling?) milling but I dont see an option for it anywhere and I cant seem to find it anywhere in the help file I am assuming because of my bad spelling. Can anyone point me in the right direction to find this function?

 

Thanks.

You can select trochoid machining in a regular pocket path in the high speed button.

Thank you. My spelling sucks.

The pocketing didnt really do what I wanted but the 2D high speed tool path peel mill looks more like what I am looking for.

No.

Did you check the XY stock to leave?

I just started using this toolpath myself, and like it very much.

Also verify and backplot it carefully, as it can cut where it shouldn't when geo gets complicated.

According to QC peel mill is for open slots ONLY! You have to watch the entry and exits or you will scrap your parts. I learned this the hard way.

One question though, The peel mill seems to leave allot of stock for cleanup even though I set it to leave nothing. Is there an amount that it leaves no matter what? I would like to only have around .002 for a finish pass.

 

sorry this was reposted but I removed it from that other post due to thinking it was an illusion that it was leaving that much stock.

 

Marc, it is leaving about .04 a side even though I have it set to leave nothing. I am just using one drive line down the center of an open slot and giving it the slot width (watch the end of the slot!). I notice that you have to shorten the drive line half the slot width for the end of the part. I figured it would just be radius of the tool...... wrong!

Crap! I just figured out my stock left problem. The endmill is a reground endmill. Sorry.

Well, .84 slot 2" deep with a 5/8 5 flute it works great. .2 ear thickness with ears sticking out almost 3" and i can rough it within .0025 and one finish pass and its good to go. Saved about 6 minutes a part.

That is the one thing I do not like about regrounds. Who pays attention anyway?
