Thanks Jeremy. Thaty's some good info there

Jeremy,

What are the beneffits of G54.4 over G54.2?

Our Variaxis machines are Matrix controls without G54.4 option on them and I can't find any info regarding G54.4 in our manuals. Is G54.4 Matrix 2 controller option or is it available for Matrix as well?

BTW, the search option on this forum is horrible!!!!

robk - how do you like the mike lynch book? i've been thinking about adding it to the collection

It's always good to have more info, but if you already have the one by Smid I would say don't bother.

I just finished another project using Sandvik's 390 series cutter machining Ti. I used 32mm and 54mm both mounted in Big Plus C5 Capto holders.

Mill turning a fairly large part I am easily getting 1+hr of cut time per edge. Cuts like butter.

Once we'll optimize the program through Third Wave we will increase that time somewhere between 20-30% and still be comfortable to run it lights out.

Sorry Todd, but I don't use Mastercam as my programming software. Somebody else will have to jump in or maybe you should contact Jeremy or Joe on the forum here. Either one will most likely be able to help you.

^^^+1 to what Mike said

We use G61.1, but without the G5P2...

According to the manual you can not use G61.1, G61.2, G5P0, or G5P2 when G54.2 mode is active... The manual is wrong (at least about G61.1). With software updates we are running G61.1 with G54.2 active. Contact your Mazak app. guy to find out if it applies to G5P2 as well.

Did your probe not come with it's own software and programs? Are you using Renishaw or another brand?

We use G54.2P_ on our Variaxis' 730 with Matrix control.

Here is the books that I have...

Peter Smid's book is the one I use the most.

I'm sorry Ninja, but I can't help you with the toolpath (I use NX) but I remember doing all that pretty often when I did use mastercamway back in the day.

I'm sure somebody will jump in and give you the solution.

Sorry

_{I use these cutters a lot. They work great for the right application. I don't think this is the right app. for it though because IMO you'll either gouge the part or not clean it enough in some areas. I did not draw anything out to support my comment though and I don't know what tolerance you need to hold.}

_{I would do it with their undercutting tool instead} http://www.harveytoo...eywords_E_52820

^^

Yup... Late 90's... We're talking a long time ago here when it comes to CAD/CAM software.

I have used the moldbase option in the past. It was an awesome tool. Not many people are familiar with it. I believe that V8 might have been the last version to support it.

FYI, the person that created moldbase worked for the same company I did @ that time. He did end up going to work for CNC Software. His name might have been Ray, but it's been too many years for me to be sure.

Pretty cool Daniel.

I have inquired about that a some time ago here as well as on integrex machinist forum,but nobody was able to help me. I have also asked Mazak for help and have not gotten anywhere.

Right now we use coordinate system rotation (G68) but that is the extent of how far we go with our right angle heads. I would love to be able to use TCP to be able to do true 5 axis with our right angle heads.

I always run my threadmills from the bottom to the top. It does not mean much for thru holes but I sure don't want to be doing that on blind holes, as there may be chips on the bottom of the hole.

IMO, it's a good habit to be threadmilling from the bottom to the top.

What threadmill are you using?

Internal or external, I have never used M04 with a threadmill yet for right hand threads.

Unless you are making left hand threads you should be using M03 while climb milling.

@ Rob, you can unbunch your drawers. I essentially said the difference between the Mitsui and the Mazak is the difference between Matsuura and Haas.

Please excuse my ignorance, but I would like you to explain your comment (no, not the drawers' comment, LOL)

Tom asked for suggestions. I offered him the information on the machines that we have that would suit his needs. You came in here belittling the product that we use (and use very well I might add) with nothing constructive to offer relating this thread. I am not commited to a "brand" , nor do I care what Tom's company decides to buy. I am interested in a tool that will do the job, and there is not that many choices out there when you start getting that big.

You're programming in NX aren't you??

Yes, but I don't think that is relevant. From my understanding IHS has a very good post for those machines.

They were somewhat involved in the process, but not really pressuring us since we were meeting the deadlines. There really was no sharing of any sorts along the way. The e-1850 was actualy bought for the swash plate project.

http://www.mmsonline...und-the-process

third paragraph:

 

 

Early results have affirmed the validity of this experiment in DFM. The largest of Sikorsky’s three new five-axis Mitsui Seiki machining centers is now producing two of the biggest, most complex titanium components it has ever designed. One is a main rotor hub that measures 66 inches in diameter and weighs 2,450 pounds before machining. With the fixture, it weighs more than 10,000 pounds. The other is a rotating swashplate that measures 78 inches in diameter and weighs 1,450 pounds before machining. A high-torque spindle is one feature that is essential to machining titanium workpieces of this size. A 1,900-mm table, designed specifically for this application, also makes a significant difference in fixture design and rigidity.

 

 

http://www.mitsuisei...m Machining.pdf

We are machining the same swash plate for Sikorsky on our e-1850.

Mitsui Seiki... Mazak. Hmmmm, Matsuura.... Haas. Decisions, decisions.

 

Not!

Please show me a mill-turn Matsuura, Mitsui Seiki, Okuma, etc... with 120" X travel, 72" Y, and 70" Z then make comparisons.

We do have all those brands in here and are happy with all of them.

I am very happy and satisfied with the Mazaks that we have here, but I am also familiar with Mitsui Seiki from my days @ Pratt & Whitney. If we were comparing apples to apples I would choose Mitsui Seiki over Mazak any day, but none of the e series have failed us yet.

^{We have a few Okuma LU45 twin turret and LC50 single turret lathes in here. Real workhorses and never break down.}

^{Congrats on the new toy}

Use the calculator @ the bottom of the page to get your power requirements.

You could control your RPM by changing the size of the hole in the retention knob.

They are very helpful and there is a 10 day trial policy as well.
