So I'm trying to run part simulation on this control and have a few questions? Where/how do you import a part model for it to show up in the simulation and what format STEP IGS? I guess I'll be taking another manual home tonight for some late night reading:cloud9:

Nikken vs Haas 4th Axis
Okay it looks like a Nikken is about twice as much as a comparable Haas, but also about twice as fast and at least twice the brake torque...and it's yellow! The Haas is actually more accurate (15 sec vs 20). Is that about all it comes down to, physical dimensions aside? I have an old Haas 4th and really haven't had any problems with it so I, personally, can't say "durability" seems to be an issue... Any input or experiences would be appreciated!

Threading preference in high temp alloys
Looking for advice on the best way to approach threading in high temp alloys; Kovar in this case. Holes range from 0-80 to 1/4-20, some blind, but mostly thru holes. I have formed a 2-56 already with great success. But I am running a low HP machine and don't know how it will do with the 1/4-20's. I am also nervous about using a cut tap in this material; run over one chip and its good night. What would you guys recommend?
Thanks,
Dan

Jashone lathe rebuild
Hi everyone there , I have a jashone lathe that I am rebuilding. I bought it used from a company and it's a manual big bore 6 inch inside diameter. Everything works as far as I know, however the problem I have is that both sides of the spindle leak oil and while oil is cheap they are not giving it away. I took it a part and was expecting to find a lip seal however there was none. I found instead a large sleeve with triangular grooves in it. I can understand in general how it's supposed to work however it still is leaking. any ideas on to how to fix this problem would be appreciated.I couldn't find any information about it online and Jashone lathe are rare.

Cutting soft chuck jaws
Just got a new chuck for the old Okuma turning center.
The old chuck was worn out.
So the old jaws I cut for it were cut with a taper to them to compensate for the the worn chuck.
With a new chuck do you add ANY taper to the jaws.. ?
More information.. The parts I run are only 5/16" diameter.
I cannot bore the jaws on the turning center for that diameter.
I clamped the jaws onto a 5/16" rod, and turned the outside of the jaws to establish a reference to the true center.
Then, off to the knee mill to cut the jaws from the reference surface.
With the old worn chuck I shimmed the jaws to taper the grip surface and comped out the taper in the old jaws.
With a fresh new chuck should I add any taper at all to comp for any deflection?
My guess is no.
Always here to learn..
Thanks again.

Iscar P290, anyone using them?
Im working on a part that starts as a 6x6x8" chunk of a36, around 95 lbs and ends up 17 lbs. machining half way down and flipping over. Im using a 2" iscar h600 high feed in a Haas vf2 to profile the outside but is not very efficient. Most of The width of cut is around .25 to .5 wide, the widest is 2".
Considering using a 1.5" or 2" iscar p290 instead, taking more depth slower and stepping in at the widest section. Or they also make a p290 1" diameter with 1.4" loc, multi inserts per flute. Could do a hsm strategy with this tool. Does anyone have experience with these cutters? Am I barking up the wrong tree for a haas?

Anilam 1100m Lag Over Max Fix and other Anilam 1100 errors not covered in manual
Long time lurker, first time poster. Typically I lurk when I can't get answers over on weldingweb.
Id like to share with the community how to fix / how I fixed the lag over max error and some of the possible physical problems that can cause it.
Before I continue, I have to give credit where credit is due.

This guy is the best. Went above and beyond to help me get this old machine up and running. The entire crew at H&W are top notch. Jonathan provided the documents I have attached to this thread.
On to the fun.
Warning: I am not a licensed anything. I am not a lawyer. What you are about to do is dangerous. By reading this, you and no one but YOU is liable for your safety. Your mileage may vary. May contain traces of tree nuts. No baby seals were harmed in the making of this thread.
BEFORE WE BEGIN
1.) Make sure your machine is plugged into a dedicated 30amp (min) 120v service.
2.) Check to make sure your table X and Y is not stuck, binding, or otherwise overly hard to move.
PRELIMINARY TESTING
1.) If your machine has a MANUAL / AUTOMATIC switch on it, flip the switch. My switch, located on the back of the cabinet, had been bumped in the moving process when I purchased my machine. No matter what I did, I would get the LAG OVER MAX error. I flipped the switch and we were in business. (This was my first problem)
2.) IF your machine still runs the AT style power supply, make sure the switch is on and the motherboard is getting power.
3.) Physically push the limit switches and make sure they throw an error.
4.) Check all Amphenol style connections for corrosion, moisture, tightness, pushed back pins, missing pins, or broken pins.
5.) Make sure the small watch battery on the motherboard is fresh and new.
6.) If your machine controls an automatic oiler, either remove it, disable it, or find out if it is 100% working properly and reporting to the CNC system the correct parameters.
ELECTRICAL TESTING
This is where things start getting deeper into the system. If you follow the directions EXACTLY, you'll be fine. Remember, you're dealing with high voltage here in some parts of the cabinet.
1.) Make sure your internal power supply is putting out the required voltages. Also make sure that the power supply is a minimum 400 watt. If you can not find the AT style power supply, buy an ATX power supply and get an AT to ATX adapter. Take a 10 amp blade fuse and connect the switched power leads together.
2.) Make sure the big blue capacitor is showing 170 or more output volts while under power.
3.) If you have performed everything above, see the two attached documents. FOLLOW THE DIRECTIONS EXACTLY. Take your time, be cautions, and you'll be fine.
SERVO CREEP
1.) If for some reason you get the LAG OVER MAX ERROR fixed, but the servos creep, make sure your No Motion Gain Table - Setup screen is exactly as follows (for X & Y systems. I do not have Z control or Z servo):
1. Kp X 10 Y 10 Z 0 U 10
2. Ki X 10 Y 10 Z 0 U 10
3. Kd X 0 Y 0 Z 0 U 0
4. II X 1 Y 1 Z 0 U 1
2.) If the X or Y servos continue to creep without being commanded to do so, run the Tuning Procedure attached to this thread.
DIVIDE ERROR
If you try to run the diagnostic disk, and you get a "Divide Error" it's because the main software is a later version than the Diagnostic Software. The two must match in order to be used. At one time there was a download page out in the world to get the Diagnostic Disk. If anyone can share this, Im sure many of us would be grateful.
PROG. CONTROLLER is disabled Error
If you get this error while in AUTO mode, and can't get your program to work, try making the machine start off with a modal move first - to any where really. Then it should run just fine. Not sure why this works, but it does.
LOSING X OR Y COORDINATES
While machining a few parts this weekend, I had a few crashes due to X deciding that it was 18,000 inches off where it needed to be, and that an instant rapid was the best way to get to where it needed to be. Cutters and materials don't like that. Turns out these machines really do not like power surges, or even blips in power service. We had a major windstorm come through this weekend while I was trying to machine. After the storm, I ran several parts without problems. If any one else has any ideas why the machine would randomly lose its mind and run wild, Im all ears.
If any one has any comments, corrections, or other notes they'd like to throw in, please let me know. Thanks again to the community for letting me be here.
Edit: I can't attach the files so I used a file hosting service. If it doesn't work, let me know.

Drilling Ø0.2mm holes on aluminium
Hello
Thank you for reading my question
I do not have any experience in drilling 0.2mm holes on aluminium
I am not sure exactly what sort of aluminium it is, and I am not sure even about the type of the drill but I think it should be carbide
But what really surprised me they machine these Ø0.2mm holes mounting the drill on a collet
Collets sometimes can run up to 50microns out or less, it depends on the quality of the brand of the collet, and if you mount the drill in such collet I am sure the drill will break
I would like to hear some experience of machinist who drilled this kind of holes before, and what sort of holder did you use and what sort of run-out, if you checked the run-out if of course
Thank you in advance for your support

Problem with Mazatrol Milling Program
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 recently have been learning about the live tooling on the machine and 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 that the machine is not allowing me to use the end mill to work as a roughing tool. I have the tool set up as a common tool in the tool data but every time I try to run the program the tool just comes down and goes right back up and indexes to the next tool. If I set it as a finishing tool it will complete the task but it takes the complete cut in 1 pass. I was also wondering if anyone knows where the parameter is that controls the depth of cut for the radial and axial dimensions. I appreciate any help you guys would be able to give.

0T-C Lathe Control Not Properly Threading
I have a Korean made lathe with an 0T-C control. I am having a problem with threading. I initially had some chatter in the threads. The facing/turning operation was perfect as well as the boring cycle. The next day I run the same program and my threads come out all torn, like the control is not repeating the starting point. Here is my code:

Here is what I have done, nothing has fixed the problem:
New encoder
New Axis Control Board
New Main Board
For some reason the Z Axis appears to be not starting in the same spot or the spindle synchronization is off. You do not see any deviation in the read out at the control.
All of this occurred after turning the machine off and restarting it the next day. No one else runs the machine but me, no crashes, etc
I am using Carmex Full profile threading inserts, same result with a partial insert. Any suggestions?

Figuring out CNC with small cutters...
HI all,
Having finished building my moving gantry mini-mill and also having a job in mind for it, I have been messing with settings etc but keep getting busted cutters so obviously I am off target still. To date, all my milling has been on a Bridgeport and never with cutters this small.
The job I have is this..
http://www.mycncuk.com/attachment.ph...5&d=1457967500
Material is 5mm 6061
I have a Fog-Buster style coolant/lubricator system.
Tools I have are YG Alu-Power...
Single-flute carbide 5mm, Limits - 12,000rpm, 1800mm/min feed, 190m/min, 0.150/tooth load
Single-flute carbide 2mm, Limits - 23,000rpm, 1500mm/min feed, 145m/min, 0.065/tooth load
The small holes are not milled, I have a drilling jig for them as they match another part.
It's the 2mm tool that is suffering, I can get the job done but only with very light cuts of 0.6mmDOC and 0.1mm @ 23,000rpm and 450mm/min (0.1 finish allowance from first cuts) however the surface finish is poor.
The first cuts are done with the 5mm tool and that leaves 2.5rads in all the internal corners of course but when the finish pass comes these are bits that snap the tool - its more like slotting here than finishing I think.
I am trying to use HSMAdvisor for speeds & Feeds, the feed slider at 30% for finish passes as it shows. On 0.6mm DOC it finishes the job (slowly) at 2.5mm DOC which is still within the tool specs & 178mm/min feed it snaps the tool when it bites a rad from the roughing pass.
The surface shows diagonal chatter marks. The finish from roughing is perfect.
Clearly I have lots to learn but is there a "safe" way of working out S&F or does it have to be expensive?
I have also been advised that the data I have on the tool chip load is wrong and is too high for a 2mm tool, but it came from manufacturer so who would be right?
I realise the 2.5mm DOC is likely way too high as the cut path includes features that result in a slotting cut and that's not possible with this depth of cut, lesson learnt.
Is there a safe way to learn cut data as i am getting low on 2mm cutters;)

RS232C, connect multiple machines using only 1 cable and a junction block?
The title isnt very clear but basically I need to hook up multiple machines to our computer using rs232 cables to send/receive programs. I have made and run rs232 cables several times before so I know how it works normally, but the new shop we moved into has a firewall we cannot penetrate and dont want to run a bundle of 5 cables ( and more to come ) up the firewall if i can avoid it. I am trying to figure out if I can run just 1 cable up the wall then run it to a junction block which will be connected to all the machines. Basically when we send a program it will send to all the machines but only the correct one will be receiving and vise versa. I think it will work but dont want to go through all the hassle just to discover it will be unreliable or corrupt the data somehow. Anybody done this before? Ideas?

DNC with Fadal question
I'm a newbie to Fadal CNC mill 2216 with 88hs control.
Group 9 codes, such as canned drilling cycles have an odd R value. (I'm used to using the Fanuc format)
I have no problem understanding it to be "R0+0.2" as being variable "R0" with a value of "+0.2".
The issue that I'm having is that when I use "Tera Term v4.82" or NC Fadal v1.2 to transfer a program to a PC, the "R0+0.2" gets changed to "R+0.2" from the machine.
Going to the machine, it stays intact.
For example:
When I transfer a file from the machine, all of the g-code program is perfect except all G83 and G84 lines. This is where the change occurs as below:
IN MACHINE:
G98 G83 X0 Y0 R0+0.2 Q0.3 Z-1.0 F3.
RECIEVED BY THE PC:
G98 G83 X0 Y0 R+0.2 Q0.3 Z-1.0 F3.
FROM PC:
G98 G83 X0 Y0 R0+0.2 Q0.3 Z-1.0 F3.
MACHINE RECEIVES:
G98 G83 X0 Y0 R0+0.2 Q0.3 Z-1.0 F3.
As you can see, the code stays intact, without any change from pc to machine.
The issue only happens downloading the g-code from the machine to the pc.
Is this really an issue? Will the control make an assumption that an unassigned "R" is equal to "R0"? We can see the "V" variables, but how would you check the "R" variables?
Since I know the issue, a minor nuisance, but I can easily find and fix all instances. My concern is for the less experienced operator who can't read g-code at all.
Does anyone have a fix for this issue?

Lathe tooling nightmare
So here's one for you that might actually set you to drinking; I am pretty close. I will attempt to keep names out of this, but if one should slip, I will plead the 5th. I have brand A cnc lathe that has been on our floor since June; still under warranty. It has been making good parts for us but the sub spindle has been showing progressive and increasing run out in the past couple of months. Still under investigation as to why brand B collet chuck cannot run better than .001 in both cylindrical and conical run out. Even worse is that it does not repeat even the error when un clamped and re-clamped. This is a 42mm quick change system. While they 'investigate', I have replaced brand B with brand C collet chuck in 16C. It indicates less than .0001 on the clamping surface. So let me preface the kicker with common knowledge that will make you go 'hmmm?'. Brand C does not make collets. However, brand D and brand B(same as the mfg of the first chuck) both make collets which I have been using for some time in another machine. They both work great there. Brand D does not make the special decimal size collets I need for my sub spindle second ops, brand B does. Now the good part; brand D collets run great in the new brand C collet chuck, while brand B collets aren't worth a damn! Have tried everything that I can think of to make them work to no avail. Even the mfg of said brand C collet chuck are perplexed.
If you're not following this, its ok, I'm starting to lose my mind over it too. These are supposed to be 'industry standard' collets and no one has an answer as to why they don't work. Perhaps someone out there in chinistville has a solution to this, besides making emergency collets for every job that comes in the door or dumping the machine, but I think I am SOL.
And yes, brand B collet chuck was bought from the rep with the machine, so it too is technically under warranty. However, I don't expect any miracles on that front. Won't know anything until they have finished inspecting it.
Hope that brightened up your day, bottoms up!

Heidenhain 415B communication
Hi all,
I haven't messed around with classical rs232 interfaces in a long time, but now that we got an used milling centre with a Heidenhain 415B control it's time to get into the game again.
Does anyone have any tips to get this working? What applications with what parameters can be used? I'm having some trouble as when I try to enter into user defined settings with a keycode listed in manual I'm getting a memory full error. So I can't confirm what parameters (stop bits and so on) are in use.
I checked physical interface and made sure that the db25 port on the control is in fact connected. Also I confirmed that in fact the machine sends something out when it's supposed to, I just can't seem to find out what it sends and perhaps the stop bit or something is a mismatched, as the PC's end doesn't stop listening using heidenhain's own software (tnc remo server).
I've soldered a few cables to try and bought a Moxa serial port server to be installed on the mill, as well.
Any tips to try?
