I used to work for a press tool manufacturer, and i has set up a template file, where, levels, planes, machines, were all set up, but what we also had. was a "c-hook" which when run, would move all holes, pockets and geometry, to set different levels, making setup and programming very quick, i wonder if this c-hook is still available ?

prime is a Chook, once loaded the tool library loads with this

ok so that's roughly equivalent to U.S. 1045 steel. 

We have an Okuma LB4000 with a 50hp(i think) spindle, so we should be fine in that department.

Thanks!

Have fun with the tool, it makes a hissing noise while cutting

I wonder if you could do 6mm per side on a 75hp machine with a rigid setup. Was taking 13mm per side back in in early 90's on a VTL and would be curious to compare this against some of those conditions being offered up by prime turning. 

No reason why not, but obviously you would not get 1mm/rev of feed rate.Sandviks selling point(to me), was they could not get the insert to wear, i reckon, i could have run the insert at the speeds/feeds for around 60 minutes

3mm per side I assume? What material was this?

O8om40 steel, EN8, and this was 3mm per side, i have a 100KW spindle, and the tool ran about 30% of power,

Jeff, i trialled this tool for Sandvik, we ended up at 3mm depth of cut, 0.3mm plunge into the radii, 1mm per rev, and 285 mtrs/min, the tool ran for around 38 mins, with no discernable wear

You need to use the plunge feedrate, it should be set around .3mm/rev, on the radii into the part, then upto your set feedrate for the roughing

Shrinivas, try this, I created a standard grooving tool, turned the tool to -40 degrees, set up back offset.

Try creating the face groove tooling as a custom tool, bit more work, but this is how I have set them up

I had no problem with this, but....you do need maintenance

Greg, all of my lathe tools are HSK, and are custom. I assume the geometry is fine ? and tools are drawn, when tool changed. with the insert in the correct position ,i.e. facing to you/ facing away from you 

You then need to define the tool correctly along with clearances, this is the most crucial point, what i do with mines is set the defaults, then post to check, orientation of tool, spindle direction is correct, once i have got these done, it works fine, I am off work at the moment, so cannot check your files. So hope what i am saying is understandable.

I had lots of problems with 2017, especially it crashing, constantly,

2018 is a different ball game, for me much more stable, i have not had one problem with it at all, So my opinion, is to upgrade

You don't have to import it... the chook installs the Prime tool libraries. Just look in there for your tool.

Thanks Jeff, All of my tools are from files that i draw up, (as i do not have millturn), so to get the B axis tooling, i have to be creative.

Ok, downloaded and installed. Looks good.

The next question is how much can we push these tools? The ReadMe didn't really specify, do I find that info from Sandvik?

I have run the "B" type tool, on EN9 steel at 275mtrs/min rpm`s, 3mm depth of cut, and 1mm/rev, the tool cut for 34 mins, abd i could not see any wear on the edge.

Interestingly, i have tried the C hook, but got the error that i needed to use a coroplus prime tool, How can you import into lathe ?

I ran that Seco.  It doesn't do as well in 4140 and like materials.  I also prefer the flat surface the iscar leaves.  I'll run it and leave 0.02in/floor and then there is no semifinish.  It will also face like a mofo and leave a fantastic finish.

That Seco did really good in A36 tho.

That info is good to know, cheers

try this seco the video is on there website, I have one here to trial, but not started yet

David, thank you very much, it is amazing how you get stuck into a rut

I programme two large millturns, and I do not use lathe stock or the millturn add on, I use top wcs, set my stock as a revolved solid, and use the one stock through all turning/milling drilling operations. I have used this method for years and have had no problems with stock updates. I have attached a file to explain better, hope this helps !

Now you've done it Dave. Through that link you've indirectly mentioned a *special* club that shouldn't be mentioned.

Storm clouds will be gathering - haters are lining up to hate...

Ooops, is this a bit like mentioning HAMLET ?

newbee i look forward to it !  

i do like "newbees best ever day" well done, it is good to get a dream realised

Nothing jumped out at me in 2018 MT

I am wondering, if like like Iscar, when the HEM milling first came out inMCAM, it would only activate the option if you used the Iscar HEM tooling library

here is the reply from Aaron eberhard

COMPRESSOR SAM (4/6/2017)yes you`re memory is correct !

on another note, is the Sandvik prime turning going to be added at the official release ?

We're hoping to get it out before the RTM.  We've wanted it out with the betas, but there's been a bunch of logistical issues that have kept it pushed back.  Hopefully with PC1 or 2 you'll be able to take it for a spin.

Samuel, there is an example on the main mastercam site (link below), hope this points you in the right direction

https://community.mastercam.com/TechExchange/Parts/53

Gents as promised, file attached, there was very little noticeable wear on the insert after one part, I reckon, we would get three parts before changing.

NEWBEE, what is wrong with being a tight a***d jock ?, need to buy you a beer sometime to change your misconceptions, but you will need to renew youre passport before you can cross the border (ha ha) Yes I bit like a big guppie !!!

When i get back into work tomorrow, i will post the file, and you can see how it was completed. very simple concept, no need to get the code generator.

I 

the Sandvik reps asked me to trial this, I have two WFL`s 100kw spindle power, i run the part on EN8 steel, 285 metres/min surface speed, 3mm DOC, and 1mm /rev, it drew 15 kw in power, i was very impressed with how it cut, but............the inserts are 19 pounds each, with two edges, they are not offering discount, this method is actually slower, than the  process just now, and when you work out the cost per edge, more expensive, (i run 160612 cnmg at 270 mtrs/min with a 8mm DOC and .5mm/rev).
