Sorry my dad passed away on Wednesday and I was just popping in after taking of things for his services next week. Yes I could make a machine dance a jig cutting that chamfer, but KISS (Keep it simple stupid) is best here.

Let those you love know you love them.

Sorry to have heard this Ron.

May your Dad RIP.

Thanks.  Yes, I think the Mitsubishi hardware is good stuff.  I was totally blown away with their tech manuals and even phone support.  Wish the rest of the machine was that nice.  I think I know what you are saying on the turret.  They use a cam to index the turret so damage there could be a disaster?  

Yes that's correct. The turrets have Sankyo name on them but are made by Sandex (same manufacturer as for the milling machine toolchanger camboxes). They have a servo drive with encoder to give position, and a cam slot for the index, with needle roller bearings running in the cam slot.

 We had (allegedly but not sure) insert go on a boring bar which was deep into a 2.5" billet and it caused the billet to eject from the soft jaws.

Apparently.

Anyway, the billet definitely came out....resulting damage was the needle roller exploded in the slot which dented the cam slot, which because there was no hirth/clamping, we had float on that turret position for ever more. Not much, and as it was radial float (about 5 thou), it didn't affect the diameter/size, so we used that as a permanent rough pocket going forwards.

Other damage was the Z rails needed replacing - if you look at the machine design, and see where your tool is in contact to the work, follow it up and back over to the roof of the machine - there is a HUGE amount of mechanical advantage (leverage) from tool tip upto the Z rails. Hence them getting "dented" in the crash.

So treat it with care and it will do some good work. Treat it as a robust heavy duty mill-turn, and you'll snap it in half!

You are correct that codes are extremely close to Fanuc.  This machine runs NEC axis cards and Mitsubishi drives and motors.  Obviously we are on borrowed time with the whole thing anyway, but if you have priced a twin spindle, Y axis parts maker lately, we at least want to try here.  

When you say MPMaster, do you mean the MPLMaster?  

Yes - Reading the comments I was going to add that machine models didn't just have Yasnac, but also Mitsubishi as well as others with Fanuc back ends.

All front ends were Hitachi own proprietary software written by their own sub-contracted software house.

You're lucky having Mitsubishi as yasnac support is next to useless.

Don't bang the machine as the turret has a roller cam box with no positional clamping....the Z rails are up and over running on the roof of the machine and if you have a smack, these can be taken out too.

Also the Y axis rails are about 12mm wide.....

Treat it gently and they work well - trochoidal tool paths for any milling is advised as 12mm dia is a large cutter which is great for making "grippy surfaces" but not so good if you want to cut a good finish.... :) 

Hicel 23....It's just a single spindle CY with the majority of code the same as a Fanuc?

Looks like Siemens shopmill/turn.....offline = NX or Top Solid....?

In my case we do pump cases, they may be sent out to have 3/16" all over but come back with 1/2" in the bore .100" on a face ect.. alot of strange radii in there too. would you hand measure a whole part like this? im trying to see if maybe other companies are using any scanning technology to take the guess work out of measuring some of these things. also i dont have any experience with Verisuf. 

You've answered your own question....If the part comes back with unknown sizes, it has to be measured.

Or as Matt says - you cut safe (air).

Correction. Looks like auto desk bought the vendor. 

If AD bought them, they're as good as history.....

A few years ago a local shop had Mazaks and #2 came in with the spindle direction flipped so had a new post.

Then they bought #3 so had 1x post for 2x machines, and another post for the other.

I would have changed the spindle direction parameter and had 1x post for all 3....

What I've done in the past is drill to just shy of the crossover..then mill past the crossover and repick up drill after the crossover

This. 

Drill to nearly break through, then spiral ramp with an 8mm cutter so you have plenty of tool movement through the cross hole to the solid, then continue drilling.

Depending on application....I've mentioned before that in a couple of times the only thing that worked for me was an ER25 holder. Schunk hydraulic, Showa micron chuck, shrink, all rang like a church bell. ER25 was quiet as a mouse.

Just checking and these parts were ally, and the tools were:-

6mm Dia 2Flute x 7mm LOC x 88mm relief x 130.0mm O/A  - 90mm out 
10mm Dia 2Flute 40Deg x 10mm LOC x 90mm Relief x 130mm O/A - 90mm out

Harmonics are a funny thing....
 

Haven't read all....but holders.

I had a feature similar dia to length ratio (although a 5mm cutter) and couldn't stop it ringing like a church bell. My mate said use a ER25 holder.

I told him he was having a laugh, as we tried hydraulic shcunk, showa microchuck (mechanical), and just tried a shrink and was now outta ideas.

ER25 was gravy. Harmonics are a funny thing....

In general, I'm a big fan of YG-1.   They always seem to come out as a great choice when you're comparing the cost/life/material removal/availability matrix. 

I love their dream drills, though often I've find that Kennametal is just as good and a bit cheaper & more available from the local tool suppliers that I try to deal with, at least here on the East Coast.  But as always, you can choose to dance the "I have no idea what I'm actually going to pay from MSC until I order it" purchasing dance... 

+1

Dream drills in the UK, are one of if not, the best value for money carbide available. Great size and finish.

I really like the YG-1 Alu-Power endmills for Aluminum. I always say if you have chatter issues with them....you are doing something seriously wrong.

For extrusion work you may need to play around with conventional milling areas that are weak, so they don't grab on you. 

+1 as they work REALLY well in this situation.

Other option is Seco Jabro/Tornado - can't remember the number, but it's a 2 flute slow helix but sharp hook. With extrusions, 3 flutes and high helixes can drag in or lift, where the straighter flutes (high hook) just cut a treat. I'd use a 12mm dia max.....

For Ti have you tried the Garr VX-7 endmills with their new AlCrn based coating?  With no changes other than the coating, we got 600% longer tool life!

I snapped a 12mm VX5 once cutting 304 - it didn't shatter, just snapped at the top of the flutes. It had only done a couple of parts and the snapped/bottom still had razor sharp teeth. The sound it made was like a shotgun going off - one hell of a bang! Only one I ever had a problem with - great cutters!

If I knew what you know about coding Mastercam would look and do completely different on my computer.

#CrazyCAM

My rules, treat toolpath groups the same as WCS - a separate one only for every operation.

OP1 G54 VICE (#1 toolpath group)
T1

T2

Blah Blah

OP2 G55 FIXTURE#12345 (#2 toolpath group)
T1

T2

Blah Blah

Then if a simple fixture (a couple of tools etc such as chick jaws) was to be made with the job, another separate toolpath group with the fixture toolpath within that so it's saved with the main prog. If it was a more involved fixture, then a file of its own.

And for Rotary work, the 1x toolpath group with the 1x WCS and planes planes planes! 

The money is good!

But there's not much of it.....

Constant chip load, no it doesn't. Constant engagement angle, yes. 

I'm not exactly sure why there is not an option to keep a constant chipload or maybe even MRR constant, I assume it is a patent infringement on someone elses toolpath as it seems like a no brainer to have this option in Dynamic. As is, we are over feeding on internal features and under feeding on external.

 

Have they changed the algorithm in the last couple of releases then? Specifically if you just dynamic a square block?

Unless some manual jiggery pokery, first pass round was brutal on the corners....?

Yep as Ron says, enhancement request to lock levels I submitted in the X7 era (I'm sure others too). Loooongggg time ago now....
