For a quick program at the machine, I like to keep it simple. Yes, it is conventional cut for right hand threads, but it is the least amount of code, and least amount of math.

We generally use solid carbide such as Data Flute medium helix. I haven't really found any coating working better than another because tool life is so poor. The company I work for actually makes the NiTi alloys, and most of the machining we do is for R&D. I have never had to make production parts with it, so I haven't ran enough quantity of anything to dial in cutters and coatings.

Nasty stuff. We have found that sharp tools with high shear work best. Insert cutters are iffy, as there is usually too much edge prep and not enough geometry. I played around with drilling, and had some success with Guhring 3 and 4 margin drills, but tool life was pretty short. Surprisingly, gundrilling went well. I managed to drill 2mm holes 8" deep in some test billets.

First time at IMTS for me. After a couple of days, all the machines start to look the same! To me, the Samsung looked pretty generic, but I did like the Hyundai and Doosan. We are mostly DMG and Haas here though, because of the sales and service in our area.

We've been having good luck with Guhring series 501, but they start at 1MM.

No Cobalt, they have too thick of web and the split point will not work. Use standard 118 degree point bright finish drills.

We part a lot of Zirconium and Titanium, so I plan to try the coolant through tools when these jobs come up again.

We have that USB box that we sourced from Shop Floor Automations. It still uses RS-232 for transfer, but being so close to the machine, it allows the transfer to run at the fastest baud rate. Programs that used to take 1.5 hours to send over the looooong wire, now can transfer in 20 minutes or so.

Everything from rubber rope and duct tape, to Nerf footballs here.

Containment boundaries? Might have to copy the operation and change the containment for each section, but it should get you there.

We occasionally use our system for classified work. Our solution is to keep our workstation off the network so there is no chance of a hack or spying. It is a bit of a pain when updates are needed or when help from our reseller is needed, but we get by.

I use a lot of the Seco High feed mills R217.21. 3/4" 3 flute 900 sfpm in steel 75% step over .025" step down .025" chip per tooth. I haven't tried in aluminum yet, but I believe they make an aluminum insert. Our Haas mills can't keep up with the cutter, but you can sure remove the metal in a hurry. I'd love to run them in a high end machine.

You are correct. I went back through some files, but I couldn't find the one I was looking for. I do remember getting waterline to cut bottom to top in one cavity, but I don't remember how. Maybe unchecking "optimize cut order" and reversing chain? It is there in X9 though

It's there in X8 in the Surface High Speed tool paths. I'm not sure about the 2D tool paths, I don't use those much.

You can select "bottom to top" and toggle between climb or conventional cut in the cut parameters.

I think its gray when you hide the toolpath with the toggle button.

Mostly Lyndex here.

In G81 or G83 you can use X, Y, and Z. Not sure if the post will output that, but you certainly can program different Z's within the cycle.

I think you would have to modify the post and use misc integers in the misc values tab to trigger that.

In the thread cut parameters, you can choose equal depth or equal area. There are options for # of cuts, and depth of first cut. If you need more info, click the question mark at the bottom right of the dialog box for the help menu, then click the tab on the right that says field definitions. Now click on each highlighted phrase and it will give an explanation.

Something like this.

Lathe Op.mcx-8

Three here. Mastercam on one, ops manager, level manager, multi-thread manager on the second, and Verify on the third.

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.

You can get close with SGS series 24

Our Haas lathes work fine with the E for federate. The IPR or IPM for drilling cycles can be switched in the toolpath manager on the page where the feed and speed are entered.
