I've been thinking about getting a tool height setter and/or a probe for my fadal. It is a 2003 4020 with a 32 MP control. Pretty much everything I do is prototyping work, so I can justify it. I came across this deal today:

Renishaw OMP40 probe
OMM
Mi 12 Interface
Blum laser tool height setter

All of these for what I consider to be a great deal. The price is absolutely worth it to me.

However, I am wondering what the capabilities of these on the fadal are consist of. Here is what I NEED from them:

Ability to set tool heights
Probing for quicker setup times(Writing my own probing cycles)

Here is what I want to acheive from them, but is not a deal breaker:

In program tool breakage detection(Using fusion 360 cam)
CAM generated probing cycles(Again, with fusion)
Mid program probing(cam generated)


I found a great article on how to set them up in a fadal, so that is no issue. If I go through with this, I will need help writing macros for them. But for right now, what will these probes be capable of in my machine? Thanks!

I don't want to get in trouble by naming any names, but I'm talking what would be considered "major machine tool brands" on a scale of 1-10.

It's annoying because we try to do as much service ourselves as we can but do rely on the dealers for service a bit, too, and I would hate to have to ditch a good brand machine just because the service sucks. I deal with 5 "major machine tool distributors" and I would grade them this ways:

Company "A" - 8 Always easy to get in contact with, get out when they can...usually in a day or two and almost always fix the problem that day.

Company "B" - 1 You call or email them and they never get back to you so you end up calling the salesman because he's the only helpful one who then talks to the service guy on your behalf just for another couple days to go by and have to contact the service guy again on your own and he says oh yeah they're busy so you tell them what part you need but they say they don't want to sell you the part until they can come out and confirm it's the right part but then they never come out, etc.

Company "C" - 8 Always able to get ahold of them, they are usually able to get out quick but always try to do as much over the phone as possible...they'll walk you through long troubleshooting procedures, etc.

Company "D" - 1 Good when they come in but impossible to get ahold of. Calls go to vm that never get returned, e-mails...who knows.

Company "E" - 5...whatever.

So I guess overall it's hit or miss for me. Is that what it is like your YOUR experience? Thank you!

So, not sure if this belongs here or in 'general', but I figured not many people would do this on a manual lathe, so...

I have a bunch of drums 10" long, out of 8" diameter A513 DOM. They are supposed to get .134 radius grooves, .100" deep, like a screw (rope drums). I am interpolating this with a .1875" full round top notch insert.

This all works, except this whole abortion in the snow...


What does a guy do, other than stopping after every single pass (of which there are only like 40) and cleaning the thing out while praying for death's sweet release? I mean they are super cold, love to go up the chip conveyor, and aren't sharp at all... but even with all that I am spending my entire life digging them out with a pair of dikes every 20 seconds!

I am running at 240rpm, and .003" DOC for the 'slotting' part, and then hitting it with more like 20-30 thou when opening it up. Am I running too fast or slow, or is it an insert problem, or did I quote the things too low? I am getting tired of spending 35 minutes on a 15 minute program...
I have like 60 of the things to do hopefully this week, and more to come. I don't have a whole bunch of money to buy anything crazy, but I can definitely play with inserts or something I already have a holder for...

Thoughts?

I do a fair bit of surfing the net and other machining related social media type deals. I rarely come across a Hurco in use in the wild.

My theory is that it is kind of a middle of the road machine that gets leap frogged. Buy something cheap like a HAAS then pay it off and buy a Mori.

Or do they just run so perfectly no one needs to ask questions?

We have a few in our shop (gov'ment) but I would call that an exception.

im making a part that has several live turn features followed by an .250 od
im using a sandvik .157w groover to get the od behind my features.
the part is 3.5 inches long 1.75 of them being the live turned shapes
im using a live center on the face and .750 stock size
the problem is that i cant seem to get a diameter to hold on that .250 because of what im guessing is flex in the bar being that thin
anybody have any ideas?

Hey fellas, I'm having some coolant flow and pressure issues. This is not a new problem but I've finally got enough other stuff fixed that I think it's time to work on this. On this particular machine we have a coolant pump that runs both the through spindle coolant and the flood coolant. I did some checking the other day because the flow seemed pretty pathetic to me, and here's what I found. At the coolant nozzles we have 1 GPM at no PSI (nozzles wide open) and no GPM at 10 PSI(nozzles closed). At the pump we have 6 GPM at 10 PSI (garden hose sprayer wide open) and no flow at 15 PSI (sprayer nozzle closed). So from what I gather, we have 5 PSI loss between the pump and coolant nozzles and 5 GPM loss as well. I'm thinking about upgrading to a 20 GPM pump and hopefully that will help. No pressure or head rating given on the one I'm looking at. How does that sound?:drool5:

In our workshop we have several CNC lathes/millers all using Fanuc controllers from 18 to 32i with the Manual Guide/EZ Guide option which we use extensively. We also have some Fanuc based machines without the guide option. When I need to transfer production of a complex part to an older based controller I will convert a Guide program to NC code using the NC convert command. On some guide based machines this will output the NC code with all the axis and feed values on every line whilst converting on another machine will output code with only values that are to updated movements on each line. What I would like to do is setup all the Guide based machines to output the same shorter format NC code.
Are there any application engineers or savvy’ guide based users out there who could point me in the right direction of which parameters/settings to alter. Thanks

Hi folks,

We've been trying to drill through AISI D2 steel. Couple hundreds of these. Need to drill through followed by boring.

We're using Indexable drill, WCMX style, dia 34mm.
Problem is very heavy chatter & too excessive Z axis motor load; to the extent where the motor just stalls giving soft thermal alarm. Drilling depth 100 mm, through hole.

Tried Vc 90 mm/min up to 200 mm/min. Feeds from 0.04 mm/rev all the way up to 0.1.

We've done OD turning in OP1 without any issues. Even 8-10 PCs which we managed to drill, boring works absolutely fine. Turning / boring Cuts are pretty easy.

Need guidance where we're going wrong....what are we missing here ??

I am a manual machinist in need of instruction in the G, M, and Fanuc control codes. Master CAM and CAD CAM would be helpful, also.
Are there any online courses available?
Can't find a job in the machinist field now without them. :wall:

Does anyone know if it is possible to set the tool heights in the tool table up in such a way that the Z0 of a setup can be set with only one tool and the rest of the tools in the table will follow. This is possible with LinuXCNC but I can't figure it out with the Anilam control.

Yes, I know this machine is a dinosaur but does anyone have a good suggestion as to where I could find parts for this machine? I currently am looking for a new turret spline but would be nice to know of someone who warehoused a few of these "older" parts.

I do apologize is this is not the correct section of the forum to make this post!!

Thanks!

I get error 115 "ILLEGAL VARIABLE NUMBER" while trying to run the following program:

%

#535 = 2 ( ENTER FIRST DIGIT )

I've used this program before successfully to define variables for serial numbers. No it can't seem to set the variable??

Gentlemen:
A lot of you like to write programs in G-Code and figure shapes, speeds, feeds, etc., all by themselves.
Way back, when I developed my system of teaching as simple as possible, the math for angles, radius-angle tangent points was a real problem, many, many people needed help.
Cad-Cam programs can do it all, but I always figured it was a lot more satisfying to actually do it all by yourself.
Here is a really nice note I just got back from a shop owner in MA that got my 3 CNC Math DVDs and obviously liked them.
If you need help, look over the Math section of the CNC DVD I have on youtube, put in my name Heinz Putz to see it.
Heinz at doccnc.com
Heinz,
We had a snow storm today here in Massachusetts. So I stayed home from the Shop and decided to watch MATH 1.
I am glad I did! You have helped me with a problem I have struggled with for years. The dreaded partial radius.
Attached is a copy of my work. I hope you find it enjoyable. I certainly did!
To test myself, I made a simple drawing template of a partial radius into an angle. Made some copies and then just placed some random angles and dimensions on the print as an engineer would!
I am very happy with the results. Let me know what you think.
Thank you very, very much. I can't tell you the countless hours of frustration this matter has caused me through the years.
I look forward to learning much more on the other videos.
You are a great teacher!
Stop by the shop anytime. You will be most welcome.
Regards,
John Reynolds

The manual I got with the machine says to unclamp the tailstock and manually move it to the proper place.

This machine has a hydraulic cylinder to push the tailstock after unclamping.

The fellow I purchased it from never used the tailstock, only used it as a chucker.

I have managed to move it along with the cylinder bracket but it is HEAVY.
Any one know this machine?

I have 2 pretty basic questions.

I want to go to school for programming to build my resume and help make more jobs available to me.

1. Should i attend a school that teaches cnc programming by manually writing codes line by line or should i look for a school that teaches programming through mastercam or some other popular software? Or should i do both?

2. Can anyone recommend an accredited online cnc programming course? One that an employer would look at and recognize as good?

Im installing a Blum tool offsetter into a Brother TC-S2B. Based on advice from others, I'm going to try and use the control's integrated tool offsetting routine rather than a Gcode program. I have the routine somewhat functioning, but I need to change some parameters so the machine knows where the tool setter is. The parameters I need to change are in Data Bank > User Parameters > Z Measurement, however, no values seem to appear for the descriptions and it won't let me alter them. Any time I try, I get an error [7624 SET POS ERROR] ("Setting data was attempted for a location where data cannot be set."). I am able to make changes to other User Parameters in other menus (Switch 1, Switch 2, etc.) just fine. This is the only menu giving me grief.

Other details:
- I have enabled the soft switch for "Zero Measurement Option" in the Software Switches menu
- I have tried turning on the parameter change setting in the I/O menu that you normally need to do for changing System Parameters.

Here is a video of what im trying as well as a picture of the parameter screen and the error i'm getting.

Sauter VDI turret. Made a new riser block a month or so back. After quick squaring to X travel and checking of stick holder for parallelism , ran several jobs and now have time to check alignment of turret.

First thing i found was that disc face indicated that it and/or riser, crossslide,carriage was tilted down. Indicated disc and got about .012" difference from top to bottom. i think this is probably from wear in the ways and Turcite. Shimmed front of body to riser and indicator says turret is now tilted up .001" or .002". I can live with that for now.

Next, indicating the bores of the pictured holders indicates that the whole thing is about .013" low. Will work on that later.

Indicated face of each holder as pictured above and got no more than .001" run out.

While indicating the bores, i found variations in the X center of each holder. The smallest holder is brand new and I used it to enter X zero into the tool tables. Rotated to the other tools without moving crossslide X position. The center line of holder on the lower right is some .005" closer to the center of the disc. The holder on the upper left has a center line that is .004" away from the disc center.

Is this center line variation normal? Or is there a problem with the holders? Holes in disc fucked up? Disc not centered on body? (Has a pretty snug fit on stub sticking up from body.) Or?????????

I'm preparing to machine titanium for a product of mine and while studying best practices for machining titanium, I stumbled upon an issue with machining titanium using coolants containing chlorine. In some cases it was found to cause stress corrosion cracking in some tests.

Titanium: A Technical Guide, 2nd Edition - Matthew J. Donachie - Google Books

With that said, I'm running blasocut 2000 Universal and it Swisslube Tech Sales says it should be fine becuase of the low chlorine parafin base similar to their BC940 that is better suited for Titanium.

The question I have is anyone else that runs Blasocut 2000 Universal ever have issues with titanium related to this topic? I'm not making mission critical or even areospace parts.

I will be doing very limited titanium parts so I'm hoping to get by with the coolant I'm using for the time being and if I go to do a change out down the road, I'll assess if I should make a change to a more suitable coolant at that time.

Any help is appreciated.

Hey there guys,

I'm a first time poster here, I always look at the forums for tips and tricks and figured it was time for me to register.

I'm trying to get through a 14.75 x 14.75 1 in. Thick plate of 316L stainless. I'm tooling on it in a VF-6 HAAS vertical Mill, with the New Gen controller, with BobCAD as my CADCAM software. I'm 25, and didn't know what machining was a year ago, and I'm now fabricating for a prototype R+D Shop as one of the only 2 CNC operators/programmers. What little training I have was Manual Machine based, so losing the tactile feel and squeal of cutters on the material has been difficult for me. not to bore you with my whole life story but just to give context as to what my background is. I'm over my head every day of the week.

This plate has 16 perimeter holes thru, at .391 diameter. then a .27, .16, and a .44 for good measure. I'm trying to pilot drill these diameters with a .140 HSS Twist Drill from when Jesus was a private, but I'm snapping these little f***ers like a Husky in a pile of pigeon bones. My supervisor has approved that I can order tooling if I need it, but he wants me to make sure my speeds and feeds aren't whats blowing my bits.

I've done as much research as I could into Machinery's Handbook, youtube videos, and any forum I can find related to speeds and feeds for stainless steel but I'm still burning bits. I've only run the .140 Bit so far but these are the speeds I came up with;

.44 Drill
RPM= 260.5
Feed IPM= 1.0

.391 Drill
RPM= 293.1
Feed IPM= 1.2

.27 Drill
RPM= 424.4
Feed IPM= 1.7

.21 Drill
RPM= 545.7
Feed IPM= 2.2

.16 Drill
RPM= 716
Feed IPM= 2.9

.14 Drill
RPM= 818.6
Feed IPM= 3.3

To reiterate, I've only attempted to Pilot drill with the .14 so far, and haven't made it through that operation yet. I realize this stuff work hardens quickly, but on my last two breaks it was near the middle of the plate or at the end. I'm Peck drilling at .020 a peck.

I appreciate any input provided, and am definitely interested in tool recommendations or personal experiences. Thank you very much!
