It likes the facing operation first. If you start with the facing operation, it will use the stock automatically and you don't have to pick boundaries. You can enter a step over for multiple passes if needed, and if you want a separate finish tool, just enter stock to leave and make a new finish operation just chaining the face.

It will be dead soft then. Use sharp tools with lots of rake.

Very gummy. We use uncoated carbide because you want a sharp tool with positive geometry. HSS works, but Niobium can be abrasive especially if it is alloyed. Use oil or flood coolant mixed on the heavy side. I would start about 150-200 SFPM and keep the chip load down to .001 or less for small parts/tools. It usually doesn't cut too bad, but can be a challenge to get good surface finish particularly when facing. If an endmill doesn't give the finish you need on the face, try a fly cutter or single flute tool.

We have done lots of these with Micro 100 solid carbide thread mills. Usually takes a couple of spring passes when you get that deep.

We use a lot of Kurt D60 and 688 here, but Take a look at Chick One Lok. We have a pair on one machine and they are hard to beat. If I buy any more vices for CNC, they will be One Loks.

This is my old box. New box has 64 GB ram and Quaddro K5200

Use Xform translate 3D, select all, from front to top. Then Xform move to origin, and select your point.

I like spade drills from Allied for applications like this. You can get the inserts in HSS or carbide and in flat bottom.

I'm not sure what toolpath you need, but I see that message when I have the wrong tool/construction plane selected.

In the same boat here as far as being self taught. I usually don't have much to add, but I sure learn a lot by lurking. I keep our system up to date as we have maintenance also, and I have to say, X8 is a huge improvement. The fact that they changed all the icons leaves one scratching his head, but the improvements in chaining and solid modeling are well worth the effort it takes to learn the new features.

Jib crane next to machine.

We use Acculube with a Trico Micro Drop dispenser for refractory metals. We mainly use it for turning/boring. Flood coolant works best for drilling in our application. When we machine refractories, it's very hands on, so we use manual switch with just one nozzle.

I just put a V562 from Fifthaxis on our Haas TR210 trunnion. Very nice vice, and nice models to import make programming easy. I have never used a dovetail five axis vise before, so I didn't know what to expect, but I was impressed. I was able to hold 4" square by 2.5" thick flamecut steel blocks without any prep. I hit them pretty hard with a face mill, then roughed all five sides with Seco high feed tools, and none of them came out and chased me across the shop.

Hmmm, I can't find anything that doesn't belong. I can, however, re-gen if I turn off stock compare.

I have seen this too and could not figure out what was causing it. Now I have a family of parts with the same outside shape and differing bores. After programming the first part, I have just been deleting the part model and importing the new part model and re-using the fixturing models, planes, containments, and toolpaths. All was fine until I got to the fifth part, and now one of the stock models will not regenerate. It stays dirty no matter what. I tried deleting and re-creating, and deleting and re-importing but nothing seems to work. Stock model bug???

Keep WCS set to top. Make sure the work offset in the attributes section of the plane manager is correct. Mine is always set to -1 for all planes, and my post outputs G54 for all rotation positions. Also check each operation. There is a check box in the Planes/WCS tab for assigning work offset. Make sure those are set to -1 as well. If all that checks out, it could be a post thing.

I re-read your question, and I'll try to explain what I do a little better. I dial in the face of the rotary platter to establish A0, and the OD of the platter for X0 Y0 (these coordinates go in your offset G54 or whichever you're using). Then, rotate to A90 and pick up face. Rotate to A-90 and pick up other face. Now you should be able to calculate the center of rotation. It should be close to .100" above the face of the platter when sitting at A0. I then model my fixturing and part so that it sits just like it does in the machine relative to the center of rotation. I also set all my tool lengths to that point. It may not be "right", but it works for me.

I dial in the platter to set A0 X0, and Y0 at the center of rotation. Ours is something like .100 above the platter. When programming, I use Top WCS and all planes have the same origin (center of trunnion rotation). Tools are also set to the origin point.

When I get that small, I use ER collet holders. I have some Lyndex ER 16 and ER20 that are 15" long.

I seem to always end up with waterline.

And they make oversize Helicoil inserts if you screw up like I might have at one time...

A little dry graphite on the taper helps. The problem seems worse after extended run time. I think the holder heats up and sticks in the taper. I always leave the spindle empty at night and on the weekend. We have had this happen on our EC-1600 as well. Sometimes it takes a dead blow hammer to get the tool out of the spindle if you leave one in over the weekend.

Just select the last op and it will verify correctly.
