It never gets boring seeing these big machines getting delivered. It takes 8 trucks to bring one 1850

If you wouldn't need to bypass the interlocks then service and applications wouldn't be carrying their own. Check who makes the interlock switch. It could be http://www.euchner-usa.com/safety.asp. You could leave the male inside the female, you could purchase a key, make your own, or use a magnet. Of course I don't recommend you doing any of those (to satisfy the mastercam safety patrol), but it is your machine (I assume) because it definitely is not a good idea to modify somebody elses equipment. Of course the machine designers and OSHA know what is best for you.

Michael, you might also want to get in contact with Alex aka Iskander and/or Teh Bear Without Brains Kinda Idiot (yes, he has multiple personalities but he is very knowledgeable). He also lives in Israel but I have not seen him on here in some time. He is a very long standing and respected member of this forum.

Holy crap!!!! Waaaay overpriced. I don't have my prices in front of me, but $600+ for a 1" Ball endmill is approximately 2x what I would be willing to pay (and we're not cheap when it comes to spending money on tooling). I hope you'll get good discount from that price if you plan on buying. IMO, those cutters are excellent, but I can't vouch for that size in that material from my past experience. Widia (Hanita) and Kennametal (Harvi) are the same item and good choices. Also plenty of other brands out there in our end of the world such as SGS, Garr, Promax, Sandvik, Iscar, Mitsubishi, OSG, Emuge, etc. and many smaller local manufacturers that perform as good if not better then most of the big name brands out there. Contact some of your local sales reps and see what they may suggest. See if you could get a free tool for testing.

Mike, Currently cutting Jethete M152 which is not as bad as 304(18-8) but pretty close. Using Kennametal Ø5.00 Shell Mill (KSSISR492SE44345M6) with SEPT1404AEENLD2 Grade KC725M insert running 260sfm @ .004fpt with excellent results. We are being pretty conservative. We're not shooting for 16rms, but I believe we are very close to getting it. Not sure if it helps, but it may be worth a try.

I will vouch for Supermill. Haven't tried them @ 400sfm in Ti yet, but we are running them @ 330sfm.

Are you sure it's a mastercam issue? If using TCP make sure you cancel it or it will take the shortest route to get to the other side which is right through the part.

Looks good Tom

Don't know about Makino, but on our Mazaks all you need is M820 to set TLO manualy.

If 317 is out of range, then maybe the missing decimal after the 2 might be a problem as well.

+1^^ Those K-Tool flat bottom drills are the cats a$$. Interruptions mean nothing to them.

We have a few different brands here (Urma, Big Kaiser). One of the latest projects I was working on uses Kennametal with excellent results. Sorry, but I never used the Parlec brand so I have no opinion. http://www.kennameta...x=mode matchall

We have some old Matsuura machines in here that use BT45 holders. Any leads as to who makes BT45 shrink fit holders (metric and imperial) that are not special order? Seems that Command is no longer offereing them.

It works great James. You could drill without using canned cycles but obviously you can't tap, but since I prefer to threadmill with RAH this has not been an issue yet. When using G68 I ALWAYS use that route, but on our older machines sometimes it makes sense to use work offsets instead. Reko, after entering the H value (James' decription a few posts above) enter whatever the value is from the C/L of the spindle to the tip of the tool into your Dia/Rad wear comp and call that number with -D- within your program. Use G45 or G46 to activate it (In the other post I showed you a sample where I use a variable instead of actual #, but the results are the same) This sample is from a standard 3+2 machine and I use wear comp for tool stickout.

I'll vouch for the Big Keiser stuff. We have quite a bit of their mill turn tooling in here (all CAT50).They work great!!

IJK represent whichever axis you are rotating about. This is copied from my manual; Programming format G68 Xx0 Zz0 Yy0 Ii Jj Kk Rr ; ........... Program coordinate system rotation ON G69 ; ........... Program coordinate system rotation OFF Xx0 Zz0 Yy0 : Coordinates of the center of rotation Specify in absolute dimensions the translation of the workpiece origin. i, j, k : Designation of rotational axis (1: valid, 0: invalid) I : X-axis J : Y-axis K : Z-axis r : Angle and direction of rotation on the rotational axis A positive value of angle refers to the left turn when seen from the positive side of the rotational axis.

On our 5 axis head-table machines (Integrex e-1060 thru e-1850) my preferred method of programming a RAH is to use G68. G18 or 19 will work only if you are not tilting your head, but once you do any rotating then you need a way to track the tool.

BTW, I am having a few different brands dropped off next week for try outs. Requirement will be 1 drill per part (Titex are about $140 each) and with hi production order everyone is willing to give a tool for free to make sure they get the order. I'm off to Bike Week in Daytona Beach tomorrow, so I'm out of here early today. Later

We have a lot of jobs in here that are PWA ESA (Engineering Source Approval) where the customer requires us to lock the process once it is proven. Usualy critical parts as well as rotating parts require this process (as we speak, I believe that Pratt is investigating a part that has a crack in it for the JSF). The parts get cut up and checked with a fine tooth comb. Not just the tooling that has to get locked, but the machines as well. So no changes at all without the customer's approval. Can't run the part on a different machine (can't even move the machine to a different location---gonna be fun with our move to the new facility!!), can't use a different coolant, or tools, can't play with speeds and feeds, can't run the cutter longer then it was proven for, no regrinds, etc... I did not do any of the turning programs for this part, but I think they have gotten through the cut-up by now. I know there is a lot of trochoidal paths to get into the deeper grooves, but this part is no different for what we normaly do. It'sthe paperwork takes even longer tan non ESA parts. Better make sure every I is dotted and T is crossed. A lot of autographs that I have to give with those jobs as well.

Hi Mark On the previous versions of this part (and there was @ least 1/2 dozen already with each one being different) we had no issues. We either drilled the holes or helically interpolated them, but the clearances were a lot more friendly. This one kind of limits us a bit as to what we could do. Thanks for your input.

I have only about .05" max clearance per side @ 3.3" stickout so the stickout needs to be what I originally posted. As I mentioned above the surface is concave on an ID of a hub so without spotting I would be hitting with the corners 1st. I am using 140° spot drill. We have done a few different variations of this part before, but they keep on changing the design and it just keeps on getting more complicated. I will take a look @ what Guhring has to offer. Sorry but that's the most I could show

The material being cut is In-100 (pretty nasty nickel based alloy). Currently using a Titex drill (A6489DPP-9.2) @ 53 sfm @ .003 ipr with life of only about 20 holes but we need to machine 28 per part (we have played with speeds and feeds and so far these are our best results we were able to achieve- They are almost exactly what they recommend as well, but according to Titex we should be able to cut 70 holes). We have tried the drill with coolant as well as oil with pretty similar results. This process will be locked so once the tools as well as the speeds and feeds are selected there is no way of changing them without cutting up the part again. The holes are only about .300" deep and the process includes 140° spot drill since the holes are on a concave surface. The drill must stick out a minimum of 3.5" inches because of side clearance issues. We will most likely try to sticking with oil, so no coolant through is needed. Looking at the 3 flute Garr drills series 1100H, but would also like to hear other manufacturer suggestions for solid carbide drills with above said minimum stickout and Ø.359-.362 range.

+1^ Very well put.

One of the reasons I accepted the position @ my current company about 6+ years ago was because I had the opportuninty to learn different software. I had a choice between 3 different companys' and in the end it was the challenge to learn something new that won the game.

I also started on V3... Somewhere I still have V5 brand new in box.
