Need Help W/ Mazak Live Tooling Programming

April 6, 2016, 7:19 am

Hey Guys, I am new to the site and to the world of CNC machining. I recently bought a Mazak SQT250MS machine which I have been learning quite a bit about. I am trying to educate myself on programming of the live tooling and I am struggling a bit. I am hoping someone might be able to shed some light as to why I am having an issue cutting slots and flats.

The problem I am having is when I am trying to cut slots or flat on pieces the machine is trying to go to the full depth on the first cut instead of going in increments to get to the full depth. In other words if I am trying to mill a 1.575OD part down to .245 per side it will try to do this in one pass instead of multiple passes to get down to the full depth. I see in the parameter book that D20 is suppose to control the depth of cut based on the tool diameter but I can not find any D parameters in the parameter menu.

I am wondering if I am not programming the machine correctly or do you think the parameter is the issue? One thing that concerns me is that there is no place for me to put the starting point for the cut so I dont know how the machine would know where I am starting along with the final depth. I have included a few photos of the program as I have it written in order to "make it work", but I would think there should be a better way.

machining a square with an axial tool on a mori with g112

I have a mori sl-403. I want to use an axial tool (perpendicular to z) to mill a hex that is 4" from the end of the part. I know you will use g112 to do the program but am having trouble with figuring out the numbers. I also know that the flat will not be a true flat bottom because i am using the end of the end mill to create the flat. the starting diameter of the part is 4" and get a 3.25 square put on it. the link below is a part with a hex but this is similar to what i am trying to do. but they used a key cutter and cut it with a milling tool parallel to z axis.

Need help with Pipe threads. Inserts for pitches

April 6, 2016, 1:08 pm

Hello,

we are primarily using the metric standards on threads so the inch or pipe threads are getting me feel dumb. For example, i have an insert for metric pitch of 0,5 to 3mm, and so with that insert i can cut all the threads with standard pitch - it may be m3 and it may be m90!!

But there's a huge job with pipe threads with G1/8, G1/2, G3/4, G1'' and G1.1/4 . So as far as i understood i need to buy 4 different types of inserts like 28tpi, 19tpi, 14tpi and 11tpi? Or i can only buy the insert with the biggest pitch (2,309mm or 11tpi) and cut such treads like G1/8 ?

Will be very appreciate for help

I have a problem with the command M21 M22 clamp unclamp collet chuck. Machine has pneumatic actuator,the problem is that a machine requires a feedback signal to continue.Does not have any sensor, over solenoid valve 5/2 and commands m21 m22 should include on and off.Problem is that it stops at the M21 i have to turn the key I.D O.D chuck to continue passed to m22..m99...stopped again in m21 and could again turn the key to the other side to continue...
I read that there is a function m31 Interlock by-pass but always stop there, not go...
What should appear program, If you can give me an example...Whether there is a possibility somehow to screw over the program?Machine no have pusher, pulling it manually.

My example program (test)

Looking for opinions on Romi lathes

I was wondering if anyone here had any experience with newer Romi lathes and could comment on whether they are a good buy. Specifically we are looking at a GL240 machine which has a Fanuc 0i-TD and supposedly all Fanuc motors and electronics. I'm not crazy about the Fanuc control but our current machine (that this would be replacing) has one so at least there is familiarity.

These machines don't seem to be very common so I'm having trouble finding much in the way of feedback online about them. The primary reason we are considering this brand is that a CNC tech that we have a good relationship with works for a company that sells these machines. He seems quite confident in their capabilities and I trust him but I do want some info from someone who doesn't have a financial interest in us buying the machine before committing to anything. Also attractive is that the machines seem to me to be pretty well priced, and we have been told that leadtimes for a normally equipped machine are very short.

Our shop is not a high production facility or anything, so we don't need a crazy speed demon of a machine. However most of our work is in 300 series stainless so we need at least a reasonable level of power and rigidity, which is why my recommendation to the owner hasn't just been to buy a Haas and get it over with.

Any feedback from someone with experience with these machines in any capacity would be appreciated.

We are also kicking around the idea of one of Romi's C series lathes with the Siemens control for doing one-offs and repair work, so opinions on those machines are also welcome.

Thank you for your time.

DPRNT Help Needed... Milltronics Cent6 to Yuasa indexer via RS232?

Hello and thank you for looking...

I have a Milltronics VM-24 with a Centurion 6 control, which was upgraded from a Cent5. I mention this because it probably didn't ship with a spare M code relay from the factory, should I be forced to use the M code function to utilize the indexer.

Here is my issue:
I am trying to find out if I can integrate a Yuasa SUDX-280 rotary indexer using the DPRNT function via an RS232 connection? While Milltronics technical and parts support has historically been VERY helpful with most of my inquiries, I have not had much luck with them in getting this question answered.

I realize that I can easily utilize the spare M code function and "trigger" the indexer with it's own internal program. However, I don't believe that this is the most reliable or best way of accomplishing this project. I will consider this option only as a last resort, so please let's only discuss the DPRNT option at this stage...

Does any one here have experience with this combination? Thank you in advance for any assistance!

Best Regards,
Steve

Dual vs Single Spindle Lathes

We are in the market for a new mill turn lathe. We have a couple of machinists familiar with Mazatrol, so we have been looking at an Integrex J200. About 95% of our parts need both front and back work so we have been pushing mngmt towards a 200S. The thinking is that we will have to turn the part around, re-fixture, indicate and machine the other side anyway. By the way we make aerospace airflow control valves, lots of tight dimensions and odd shapes that will be difficult to hold either way. We will not be bar feeding.

My question is, what are the advantages and disadvantages of dual vs single lathes, besides the obvious $$?

New DMG ecoMill = Mori DuraVertical

My shop is looking into another VMC. And what I was told by the DMG Mori salesman is that the new redesigned DMG Mori ecoMills are the new Mori DuraVerticals. Apparently the companies have been working on this combined machine since the merger.

I know there are a few fans of the DuraVerts on this forum. And I know there are a few posts about the (less then stellar) ecoMills. So I thought that I give this info out to you guys.

We currently have a 1035 ecoMill. And its not that impressive. But I will say that the new machines are a bigger, heavier machine... even the new 600V outweighs our 1035. There's not too much info on the website, so I don't know what else has been upgraded.

But we'll see if DMG screws this one up.

Running shaped extruded plastic on a swiss?

I have a pretty high volume application coming up where I'm going to have to turn and mill secondary features into a plastic (non-round) extrusion. I'm doing prototypes on a standard CNC lathe in a collet chuck, but the deflection is killing me. Swiss would be perfect to solve this if one can make swiss run plastic stock that looks like a cross. (big flat plus sign with one longer leg)

The part is only 1/4" diameter and about an inch long.

Has anyone done this sort of thing? Heard of this sort of thing? I'd love to shop this one out as we don't have any swiss machines right now, but want to make sure I'm not asking for something crazy before I do.

Obviously there would be some dollars in setup costs for custom EDMed guide and clamp collets, a shaped bar feeder liner and the like.

If I am crazy and this sort of thing is just not done, then I guess I'll be stuck buying a machine and doing it in house.

This is an electrical part and I'll need them in batches of 100,000 pieces so crawling through them on a chucker or milling them isn't an option.

Thanks for any insight!

Question on machien parts quotes

April 7, 2016, 12:56 pm

I looked up a chuck, and the website described it fairly well.

All the dimensions were there.
This line described what ( I assumed) was included:

"Standard Equipment: Chuck assembled with adapter, chuck mounting bolts, soft top jaws, T-nuts and jaw mounting bolts with wrench, draw nut wrench."

When it arrived, the original factory sealed box contained exactly everything just listed as "standard equipment"
There was a Chuck, it was assembled to an adapter, there were chuck mounting bolts, soft top jaws, T-nuts and and mounting bolts, wrenches, and draw nut wrench..

It looks like this came together, and all is well.

When I called the distributor, I had already looked at the website.
The "Standard Equipment" looked like just what I needed.

I got a quote for the chuck, didn't ask about anything else, didn't think I needed anything else..

The world is great...

Imagine my surprise when I got the invoice, and there was an additional $451.00 for the adapter.
The chuck was charged what I was quoted over the phone..... PLUS the adapter.
It was in the original factory sealed box, mounted to the chuck. Just like the website described it.

It was listed as "Standard Equipment" on the website that I went to and ordered from..


I called the sales guy, and he got so patronizing I hung up.


I feel I should dispute this, I think this is deceptive.

Any (helpful) thoughts ?

Romi Lathe DX-32 questions

I picked up a Bridgeport Romi Powerpath 15 CNC lathe. It has the Bridgeport DX-32 PC based CNC control. The machine has not run in a few year. The control PC is in shambles. I have two hard drives laying in the bottom of the control cabinet. The PC power supply was removed. I have an extra motherboard.

I'm not exactly sure where to start. The motherboard is a 486 board with a Cyrix processor. The power supply is a standard AT supply. All the control components are just plain PC hardware circa 1995 (PS2 keyboard and VGA monitor). I know the PC runs in DOS.

I believe the HDD is an ITE interface. Looks like there are a few solid state drives out there that can adapt to IDE. I don't know how to go about recovering the data on my old drives.

There appears to be one board that plugs into motherboard that makes the magic happen. It must be the PLC that actually runs the machine. It also has a processor chip. There is another board I can't identify. I think it just does the PC side I/O and is not mounted directly to the motherboard for some reason.

So, where do I start? Should I try to find a HDD recovery company to image my old drives or can I do that myself? If so, what do I need? Once I get the data out of the disk, can I run a solid state drive with DOS? If I can't get anything out of the old drives, what are my options? The machine has a parts catcher, bar feeder, and touch probe that will all require additional parameters beyond the basic stuff to get the machine running.

It seems like a nice machine. Box ways, Yaskawa motors and drive, two speed gear box on the spindle, 2" bar capacity, 12 station turret, SMW chuck, bar feeder, etc. I'd like to see it run.

Looking for a cheap(free) CAD jockey to do me a double check.

Got a job, had it for quite some time.. Print plus a model, customer sent me both.. Part of the dimensions are
based on a point cloud. Get 80% through these parts and notice something doesn't look right between the models
and the print....

Finally got the raw data, pump it in, do it quick and dirty, and hey.. That really is how they are supposed to look.
Doesn't look like the print, but its not the first time that has happened.. So I'm 15 seconds away from verifying
everything, make the offset... and UH-OH.. That don't look right.

On and off for the past 3 days I've done everything under the sun to prove the models are right, if they are wrong its
just going to be a pain in the ass, and/or cost me more money. If they are right, I can just keep going...

Anybody up for this challenge? There might be a box of green chile in it for you... I can send you the models and the
raw data.. And the point cloud, you can check it against the data. Basically, create the
surface, offset it properly, and compare.. There is some angular stuff in there also, and some other weird things, but
its really not that overly complicated... And it would actually be fun and interesting if I wasn't banging my head
against the wall.

This is one of those deals where I want to be wrong, but I think I'm right. How often does that happen??

Hello,

I'm looking for opinions on checking concentricity on a hole and counterbore.
I'm doing a job that a .196 hole and a .383 counterbore have to be concentric
within .001. If I indicate one of the holes dead on, then without moving the table,
what is the most my indicator can read on the other hole and be in tolerance. Is it
.001 or .0005 ? Thanks all...

Programmers, how do you control pulling/editing/saving with multiple operators?

April 8, 2016, 11:47 am

I came from an environment where each machinist was responsible for their own work, print-to-part, including programs. Now I am providing programming for repeat parts for multiple operators. Currently, I am generating about 98% percent of all the programs, however, I do allow them to be edited at the controller for small changes. I trust my operators enough as competent machinists, and I appreciate their feedback, as most of the time they have good ideas for improvements. Sometimes though, I get requests for changing the entire method of the part by one guy, and then the next time the part is run, another guy wants to do it a completely different way. How do you draw that line between making program improvements and just chasing around everyone's opinion of how a part should be made? Do you let your folks make changes to programs? Do you have the controllers locked? How do you manage all the data floating around the shop between USB's DNC's, Servers, and controllers, such that only good proven programs get saved/pulled and everything else is erased?

Hey guys. Long time no see. I need some help please!

I'm trying to make a part on a 2 axis CNC lathe.
Its similar to what is being made in this video.
Not exactly the same but close enough.
I'm having a difficult time getting MasterCAM to generate this G-code.
I created a solids model of the part but am having a difficult time with the code generation.

Do I need specialty software for this? of should I be able to get MasterCAM to do this?
