FYI-Iscar is running a promo till the end of the year taking 20% off all ISO turn. Only downer is that they are dropship only and you need to mention a promo code, AG1, to get the additional 20% off.

Dave, I do agree that cranking down on collets is bad for them especially if the shank of the tool does not fill the entire collet or if they have flats of any kind! But this is a cheap alternative to Mill chucks, shrinkers, and Hydo's for those high horse power cuts! Aside from the fact that your tool and holder extension is now at a minimum, creating a stabler cut, the versatility is greater. connormac, check this out for your shrink needs. Another cheap alternative to buying an entire CAT** Shrink holder. ER32 shrinker. The biggest benefit I have found is that when the holder is at it's shrinking end, won't hold the tool sufficiantly, you don't buy a new holder just the ER32 shrinker piece at a little more cost than a precision collet. after you get these a little more than hand tight, chuck it up in the spindle indicate the tool in by tapping on the shrink part, then remove and tighten down. It's dreamy!

-- For real heavy cutting we use Iscar low boy holders.( I'm not sure what ther are called) The whole collet is inside of the holder. Use a 1 7/16 box end wrench and get it as tight as we can.--- They are called SHORTIN Holders. You can crank down like hell on these and you won't pull your tool out!! + there is very minimal runout when using a good collet. When you use a side lock you sacrifice tool life due to runout and the tooling extension. Of course mill chucks, hydro and shrinkers work great for the high HP cuts as well but there are the associated costs that come with them.

I guess I'm confused on what your trying to do. Flipped geometry will now be -.050 of Z0.0 ? If so add the -.050 to the transfered Position data. Your stock will move with it after a regen.

Yes Crazy is right you need to re-define the cut direction. With stock tools you can lie to the dialog and say that its working on the opposite spindle (right) and and uncheck the reverse box. Then press the draw button and it should come out on top of the Y-Axis rather than below and post the right code.

This part of the post needs to be customized, as the sequence of code and the code itself varies so much from control to control there would be no way MC could put something together without alienating everyone that doesn't use it. Example of a Myiano dual spindle dual turrent post transfer for the sub and the flip. Hopefully this helps some. code: # -------------------------------------------------------------------------- #Format Assignments and Initializations # -------------------------------------------------------------------------- fmt Z 2 stck_init_z$ #Initial Z position of the stock (900-902,904,905) fmt B 2 stck_final_z$ #Final Z position of the stock (900-902,904,905) fmt Z 2 stck_chuk_st_z$ #Initial Z axis Chuck Position (900-903) fmt X 2 stck_chuk_st_x$ #Initial X axis Chuck Position (900-903) fmt Z 2 stck_chuk_end_z$ #Final Z axis Chuck Position (900-903) fmt X 2 stck_chuk_end_x$ #Final X axis Chuck Position (900-903) fmt B 3 stck_chuk_st_dz$ #Destination chuck Z axis reference position before transfer (900) fmt U 3 stck_chuk_st_dx$ #Destination chuck X axis reference position before transfer (900) fmt B 3 stck_chuk_end_dz$ #Destination chuck Z axis reference position after transfer (900) fmt U 3 stck_chuk_end_dx$ #Destination chuck X axis reference position after transfer (900) fmt B 2 stck_clear$ #Stock clearance value for stock pull operation (902) fmt X 2 stck_tool_x$ #Tool X axis position for bar stop / puller (902) fmt Z 2 stck_grip$ #Grip length value for stock pull operation(902) fmt B 2 miscops_mr1$ #Final B Position for part off fmt F 18 stck_adv_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902) fmt F 18 stck_appr_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902) fmt F 18 stck_adv_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902) fmt F 10 stck_appr_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902) #Flags stck_op$ : 2 #Stock advance operation method (902) #(0=Push stock,1=Push stock with Use Tool Stop option,2=Pull stock) stck_spindle$ : 0 #Active spindle with stock to transfer (900-902) #0=Left Spindle,1=Right Spindle clmp_op$ : 0 #The selected Operation mode: 0=Clamp,1=Un-clamp,2=Re-position (903) clmp_spindle$ : 0 #Active spindle for clamp/unclamp 0=Left Spindle,1=Right Spindle (903) tlstck_on$ : 0 #Retract or engage the tailstock (0=Retract,1=Engage) (904) toolend_flg : 1 #Flag to execute ptoolend sequence or not # -------------------------------------------------------------------------- #Postblock Section -comments only! # -------------------------------------------------------------------------- pstck_trans$ #NCI code = 900 available variables: #stck_spindle, stck_init_z, stck_final_z, #stck_chuk_st_z, stck_chuk_st_x, #stck_chuk_end_z, stck_chuk_end_x, #stck_chuk_st_dz, stck_chuk_st_dx, #stck_chuk_end_dz, stck_chuk_end_dx if toolchng <> two, ptoolend$ toolend_flg = zero #Do not execute ptoolend again after xfer else, if lturret$ = 0, [ pcaxis_off_l_sub ] if lturret$ = 1, [ pcaxis_off_l ] n$, pchg_n, "(PULL OUT & PART-OFF-BOTH)", e$ n$, "M135 (PARTS CATCHER ADVANCE)", e$ n$, "M177 (SUB-COLLET BLAST ON)", e$ n$, "M117 (SUB-COLLET OPEN)", e$ n$, "M157 (WORKPIECE EJECTOR OUT)", e$ n$, "M213 (CONVEYOR ON)", e$ n$, "M136 (PARTS CATCHER RETRACT)", e$ n$, "M138 (THROUGH SUB-SPINDLE COOLANT ON)", e$ n$, " ", e$ n$, pchg_m, "(SPINDLE SYNC WAIT CODE)", e$ n$, " ", e$ if mi5$ = 1, n$, "M180 (SYNC SPINDLE PHASE)", e$ #if mi5$ = 2, n$, "M35 (SYNC SPINDLE SPEED)", e$ n$, "M181 (PARTS CATCHER POSITION CHECK)", e$ n$, "G00 G55 B0.1", e$ n$, "M180 (SUB-SPINDLE SPEED CHECK)", e$ n$, "M139 (THROUGH SUB SPINDLE COOLANT OFF)", e$ n$, "M179 (SUB-COLLET BLAST OFF)", e$ n$, "G01", "G98", *stck_chuk_end_dz$, "F100.", "(SUB-OVER)", e$ n$, "M118 (COLLET CLOSE-SUB)", e$ n$, "M17 (COLLET OPEN-MAIN)", e$ n$, " ", e$ n$, "G01", "G98", miscops_mr1$, "F100.", "(SUB-PULL)", e$ n$, "M18 (COLLET CLOSE-MAIN)", e$ n$, pchg_m, "(WAIT CODE FOR PART OFF) ", e$ n$, "M01", e$ n$, " ", e$ n$, "M36 (SYNCHRONIZATION OFF)", e$ n$, "M05 ", e$ n$, "G00 G54 G28 B0.", e$ n$, "G00 G28 W0.", e$ n$, " ", e$ n$, pchg_m, "(END OF CODE WAIT CODE) ", e$ n$, "/2M30 ", e$ n$, "/M99 ", e$ pstck_flip$ #NCI code = 901 available variables: #stck_spindle, stck_init_z, stck_final_z, #stck_chuk_st_z, stck_chuk_st_x, #stck_chuk_end_z, stck_chuk_end_x if toolchng <> two, ptoolend$ toolend_flg = zero #Do not execute ptoolend again after xfer [ !spaces$ spaces$ = zero pbld, n$, "M00",e$ if prv_spaces$ > 0, " ",e$ "(Flip Stock)", e$ spaces$ = prv_spaces$ ] You can see I used a combination of misc. integers and Mastercam assigned parameters (stck_chuk_end_dz$) all of which coincide with the boxes inside the operations dialog. You can look this up in the MastercamX_Post_Parameter_Ref.pdf (found in the documentation folder in MCX2/) and the V9 Post reference guide that I'm sure is on the FTP somewhere. It's how I learned.

cheeveshome is right! Your crib manager is not doing his job! Go above your supplier/distributors head and call the manufacture of your choice. From my experience they are more than willing to test these tool at their cost.

Doh to many windows open wrong topic

ebottens Call your tool supplier and get a local factory rep in to test some tools for ya! 1. If it dosen't work well you don't buy it and then just test another tool from another MFG'er till you find the right fit. 2. If it blows up you don't buy it. 3. If it works your golden.

Sorry guys. Although it's on the FTP I fixed the link. For those of you that are FTP disabled. Calculator

ETM ER32 and 40

Also check the tool manufacturers web sites. Some of them offer .DXF's of their tooling.

Wrong Topic sorry anyone care to move it... Sorry

I thought some of you might appreciate this. Calculator provided by Iscar 8 sheets of calculator and convertors. The first time I looked at this I missed the other sheets. (Bottom left)

Got this figured out? Sorry I couldn't help.

Select all operations in your TP manager and right click. Find renumber tools. Something like that.

First if you are threading you need G76 output. I say put you X in the G76 line in the middle of your tolerance then work up with offsets. But keep in mind that as you move comp +X your first past amount may grow with it. It would appear this is a internal thread as the 1st X value is smaller than the one in G71(G76)? Larger major mean more material to be removed if in fact the minor stays the same. So in turn your H value will be greater. H is the amount of stock to be removed so.... Posted for a Haas controller right?

Thanks guys. I got it to work, although Miyano said it could not be done, but I had to use G107 as I could not get this to work in G112 on this Fanuc controller. And it repeats! Allowing for sizing of the thread. This was the main grey area for me, whether or not I could actually re-start the cycle and not mess up the threads.

Anyone ever successfully perform Thread milling on a lathe with only X, Z, and C axes. Using G112 you cannot move the three axis at the same time correct? So this won't work. So I was thinking of turning the live tool and the spindle on, calculate my feed from both, then move in on the x axis and then the Z. Anyone try this? I doubt it will work but for the time and tool life I would save it is worth checking out. The thread is 1/2-28 UNEF in inconel 718. Or if you have suggestions on how I might get around the, G112, 3 axes delima please ad your feed back and I'll test it out.

Use the toolpath editor for this. You can define new feed for every move you would like. Right click desired toolpath at the bottom will be the editor.

The only way you will be able to do this post side is by buffering the X coordinate that you want and having it's output for the G70. There is a problems still with this and that is if you are running rough and finish on OD and ID then you'll have your work cut out trying to figure out the way to buffer those. The only bullet proof way to ensure you don't crash this is by not using it!! We are going to have to buy MATTS. yeah!

quote: There reply Don, I’m sorry but we have no plans to go back and modify any of the older posts in this fashion. The changes coming with custom events make the old misc ops completely obsolete. It would not make sense for us to devote development time toward adding misc op support to the old posts when we really need to be focusing on developing new posts. And, I agree with you, Lathe can use some serious love from the developers. But again, Multi-tasking is the first priority. Once that is ready they will have time to go back and address other issues. This is not a post side fix!!!!!!!!!!!!!!!!!!!

I have a friend who is the new Iscar Rep. in Oregon. He's based in Portland. He asked me to put the word out and let people know he is available for applications and tooling problems if you have them. I thought they only did grooving and turning, but he brought me some catalogs and they have just about everything to my surprise. The thing I liked was that they have a nice test tool policy with the free applications help, I think they all do that though? If this is in the wrong Topic please move it. Anyway he helped me so I thought I'd take a minute. If yur in the area leave a post and he'll see it. I told him about this site.

Look at Iscar they have a great hsk line built just for these turn mill machines, maybe they'll have what you want. They can give you what they call a guaranteed test (with all their tools), lets you test the tool with a applications engineer then buy it if it works the way you want, or if you think its garbage then tell him to walk.
