We only have Matrix controls in here, so this may not pertain to you, but check your manual or call Mazak applications for some easy answers. With Matrix you have an option of using tool data or tool offset, and I belive you probably have the same option for your control. In our situation we use both within our EIA programs. Tool data for length and tool offset page for Ø (as silly as it may sound, we have reasons for this).

I'm a fan of Emuge, but for programming I use an Excel spreadsheet that I have. Works great since it gives an option of having more then 1 pass. I don't know if mastercam is capable of doing multiple passes. Let me know if you want a copy of it and I'll shoot it your way.

email sent... I will convert it if it's NX file. I know Cadkey also has .prt extensions.

Here you go Thad,

Hey Thad, this is from above quote: T5. is the offset # (not tool #)... So even though you have Tool #5 In the spindle you could tell it to put the offset into a different #. If you parameters are set correctly you should just change the T value to the offset#, or as Ron suggested you could use some logic to force the values in. Shoot me an e-mail if you want a copy of the variables that correspond to your tool offsets. BTW, it was a pleasure to meet you Ron @ Eastec

I'm sorry, but I don't want to lead you in the wrong direction when it comes to speeds and feeds since it's been a very long time. I know it was pretty slow on the feed and I took multiple radial passes. Sorry that I couldn't be of more help, but maybe somebody else will chime in.

When I was in moldmaking we used burs like Specialty Carbide and SGS . You could also get them from MSC.

After months of searching my company hired a person from California to move to Connecticut so they could help me with 5 axis programming using NX6. Trust me, the jobs are out there and they do pay very well.

+1 Doug I use NX6 for all my programming, with an exception of sometimes using Mastercam to alter/edit some older turning programs. Costs aside, NX(6)is the best software I have used up to date on both the CAD and CAM sides. Flame away

I wish that I could help you, but I am swamped with work. Not knowing what your part looks like can you get your hits along X or Y axis then do some math calculations with your variables?

The above quote was from Renishaw, but according to applications @ Mazak it will not work. I have tried probing with G54.2 a couple of years ago and had no luck. I contacted Mazak and I was told it was not possible. None of my probe routines for the Variaxis are used with dynamic offset active.

See the Features, cycles and limitations part of your manual for the comprehensive description. This is directly from the Renishaw Inspection Plus Software manual; quote: DYNAMIC WORK OFFSETS -------------------- Addition codes #5121 #5122 & #5123 are used within the software. These codes allow the software to run in normal mode and dynamic mode. This software can only be used in dynamic mode to measure component features and positions, it can not be used to update work shifts when G54.2 is active. To update the dynamic offsets parameter S5 (X & Y) & S12 will need to be used in calculations as shown below. Using this example should give you a figure in X & Y which is the difference between the centre of table rotation in XY and the centre of the part in XY, these must be within a small amount otherwise the control gives an alarm (I think it is 3mm). The Z is not controlled to the same tolerance and can be quite big.

quote: I am not sure I can probe while G54.2P1 is active to begin with so I don't know if its my code or the machine. You can't use your probe cycles with dynamic offset. We have a Variaxis 730 with Matrix control.

For turning use mostly Kennametal. Pricing is a little better then Sandvik. We shy away from Iscar because most of their stuff is molded only(and their support is the worst-@ least in this area). I have never tried Sumitomo.

I would be against your process if you were planning on using a vertical machine. Your biggest problem will be chip evacuation, and this is from experience in the past. On the VMC's when we used feed mills we had to run additional air lines just to blow the chips out of the pockets (feed mills create some very heavy chips). You would be better off on a horizontal machine, and even then I would be very apprehensive using a feed mill in a pocket as narrow as you plan on cutting.

Using collets for milling is an accident waiting to happen. Use a precission milling chuck or a shrink fit holder. Weldon holders work good, but IMO not @ 12,000 RPM. If you're using hydraulic holders do not stick cutters with flats into them. Use the right tool for the application and you'll sleep better @ night. quote: Use a 1 7/16 box end wrench and get it as tight as we can.

Inconel 792 has a Pratt & Whitney designation of 1467 with a machinability rating of 12. Go here and enter 1467 to get some sort of a starting point. Slow and steady. Cobalt will do much better in casting if you're rough milling. Ceramics will work great also if you're turning (and milling in the right application).

On the 730-5x II your max RPM for your C axis is 50 RPM (That's in the rapid mode).

The new ones do, but ours being about 3 years old did not have that option then.
