I think spring pass works as well?

oh and no probes here... they crashed all of them

they use a pin in the spindle here. zero's are off constantly and I build a .25 hole at x0 y0 z0. all they have to do is dial it in..

 I showed them how to indicate bore in and they refuse. 

IDK maybe i am the dumb one for even caring.

went to 2018 a while back, did tests and copared files etc. but today's posted program put in several G52 x0y0z0 comands. two were also g52 x0y.0001z0 any ideas what gives. my machine wont even deal with g52

it is a head head 5 axis post

any ideas, this makes me nervous.

coolant thru spindle tool will be a must. but you knew that.

if time is not issue, cobalt might do it 30 sfm .001 chip lots of pecks

I would lean toward a carbide tipped gun drill and talk to saleman on feeds-speeds per their tool.

I am mainly curious about what kind of parts are using 50 WCS...or is this just different parts and programs?

multi axis indexing at a shop that refuses to program from CL... argh but thankfully no longer there.

Tsudakoma rotary's have always treated me well.

I only have experience mounting a Haas rotary on horizontal 4th. it opened doors for us but also made a huge window of opportunity for crashes.

ours was poor man setup with limit switch at a certain z position rotated c to the next position, what could possibly go wrong, lol

Skinning the material on the back side can help sometimes too with thinner stuff (skim one side, then flip, rough, re-vise, finish if a re-vise alone won't get it). CR steel has a lot of tension in the material at the surface. Relieving the tension in one area usually causes distortion because the forces within the material are no longer in equilibrium. 

yes the skin on this material holds stress, sometimes real bad.

it can also be a bit hard, you want to get under it and even maybe conventional cut. might eat cutters

keeping source and nc files seperated helps with user permissions and lends itself to AS9100 and MBD requirements.

I must ask what you mean operators need to grab the most up to date code. is old rev. code available to them? if so big no-no.. IMHO

only latest greatest verified or proven files should be made available to general population in a shop.

we do it old school, but am currently in a one man show at this point. doesnt set up well for the future but management needs to drive that.   ??

google is you friend lol, carefull I have no verification   

Hi all.

I have 2 Nakamura lathes. One is a 0T control from 1995, TMC-15, and the other is a 1985 model Slant with 6T control. 

From day one I was always pissed that X axis was negative away from part center. Any positive diameter was a X-. Well, for anyone else that has this issue and wants to change it, this is what I did. Im still working on the 6T control since I dont have a param manual for it, but for the 0T, this worked PERFECT!!!

ES142 is X axis direction
Its located at D514-2 so just change what ever yours is to the opposite. This will reverse the motion on the axis (so it is essentially backwards)

Go into servo settings, and change the X axis direction 111 or -111 to the opposite, this will correct the motion and the axis + or -

Now the issue is homing, it will home the wrong direction now

go into parameter #3, bit 0 is the x axis homing direction, change it to opposite what it is now. 

restart the machine, rehome, and check your tool offsets. 

Unfortunately the 6T is not quite as easy. This should help though.

another post

1. Zero return X axis. 
2. Change parameter 12 bit 0 (1 to 0/or 0 to 1). 
3. Exchange the parameters between 143 and 147 but leave the signs. (143 is always positive, 147 is always negative value). 
4. Change the sign on parameter 82, do not change the value. 
5. Shut the machine off and swap motor wires on X axis servo (Switch XA1 and XA2) 
6. Locate the Pulse coder on the end of the Ball screw, and switch wires on Pin A and B, also D and E in the connector housing, If you find the pulse coder in the Yellow cap, then skip next procedure(procedure 7). 
7. Switch polarity on Tacho Generator on Pin A and B on the yellow cap. 
8. Swap the Jog '+' and '-' by changing wires. (swap wires 576 and 577). 
9. Restart the NC. 
10. If you have FAPT and are using it, you must change the sign of MTF parameter 1050.

nicely done sir

just had a guy i know call me to do some programming for him. has owned his shop for 2 plus years, anyhoo his programmer took his jacked seat of mastercam and split on him. he has lots of work and i respect him for stepping up for business but not so much for taking the free ride.

I declined lol

It's just me doing this, so I have the latitude to not make setup sheets, and I can run back and forth between computer and machine modifying things on the fly.  I'll need to get some processes down here soon.  I can't do this on my own forever.  Bout to lose my mind right now.  I've got a block of aluminum sitting on the mill.  Just sitting there!  Needs setup, but I can't program and setup at the same time.  

I feel you but its not a bad place to be in. you can set it up how it works best for you.

dont do like me and start out not documenting at least in mastercam how you did it. got bit a few times several months down the road they wanted me to make a repeat tool, was running so fast took me a bit of time to figure out my own mess. lol

i have a set of dedicated cutters in each machine with mcam tool library in detail.

also as mentioned fixtures are all standardized and modeled. 

pull it in and gram it, makes life so much easier. can dang near set my machine work offsets from mastercam seat. I usually calculate from know point on the machine dont even have to pick it up or touch off tools.

Tool shop here

doing a lot of layup molds, hand router fixtures, layup masters and all details in between so the spectrum all over as far as size and configuration.

I have a plate that lives on one of my machines with 1 inch space 1/2 tapped for bolts. I try to order stock oversize to bolt thru and tab off whenever possible I HATE CLAMPS my setup guy or programmer always try to run over them no matter how carefull (I am the programmer, setup and machinist lol).

one guy and three machines 3-5 axis I have to run unattended whenever I can so any obstacle in the way is just getting closer to a bad day.

even depth of cut is knee jerk to meh but learned moons ago not good with hard materials. it puts a wear mark in the cutter and or does not use the full potential of flute length. so when hard I stagger depths, when soft fast and dirty even depths without adding depths.

Comes down to support. My experience with MTB techs has been subpar most of the time when things went south (read: okuma 5axis head/table)

Some of those guys are like programmers that never worked as machinists....they seem to know few things and can talk the talk, but can't do the walk...

Good ones are far and few between and they command big buck.

fast talkers are plentifull and many times cost less at hire.

lets see, interviewer oh you can do this know this and this and the other and you only want this. gee i just talked to a guy with the same rep. of skillset and wasnt as social and  he wanted more. lets save a buck..

very sad

Yes it will put a fillet on. feeds and speeds determine what size. kind of an amazing tool

I have used these in the past

http://www.jwdone.com/

Yep

the last place I worked for had Mastercam so jacked up it was nearly un-usable. I tried to explain a few things to them but they had there ways and it was the only way, I found my way down the highway.

I fingered it out.

funny thing vericut support said they could not do it. lol

I know there are a few very smart Vericut users on this forum so looking for a little help setting up with our Fagor control drill cycles.

the freak part of this machine is G83 Z.1 I.1 J5 peck drills a hole .500 deep from the Z value. this is the format per the book and how our machine inturpets it. 

my problem is as I understand it vericut has macro's that you assign to the address. ie Z would be assigned to initial start point macro. am not sure what macro's to assign to i and j and or how to make it calculate j X i = final depth from z

I do not need to simulate the peck movement but would be nice.

thanks in advance if someone can point me is a correct direction

Doug

If it is like my DMI (aka DMS) . There is a bolt pattern on C and B that must be physically dialed in and adjusted.  make sure B is vertical then adjust C centered with spindle center. there is a parameter that you need to enter pivot point of B to gauge too.

probly but this place as many are is very good at tripping over $100 to save $1... lol

Gotta do what you gotta do! I definitely wouldn't call a fadal a 100k machine though... Haha

it has 80x30 travel and iron behind it. yes I know what I am running here (have run okuma, makino and old mori) but travel like that with them would be twice for good reason. I run what is on the floor its what I am paid to do. I get it. thanks

had a project to do that required tight profile tolerance. told the boss no problem our Fadal is pretty tight we can do it. oops. come to find out it looses .008 in 16-24 inch travel in x.

this was a surprise to me as the machine has been recently rebuilt, guess they failed to tune it in.

so what does a machinist do?

have not had to do this in decades lol. I have been spoiled on very nice machines. oh and don't know how many times I have been told one cant do something because of machine error. I tried every trick in my books including approach from one direction to comp back lash of which that does not seem to be the error I am chasing.

they are looking into solution to dial in the machine but job could not wait.

it has been lazered and dialed into .003 linear. but table has some drop in areas. ways are worn a bit and am sure of backlash etc. I am impressed for a ten year old machine with very hard life (previous machinists were pretty rough on it).

I guess my real question is what machines might be recommended that might be a bit tighter out of the gate. I have been spoiled with matsuura's, makino's and okuma's but we need 5 axis and loads of travel on a shoe string budget.

current machine has 76x136x47 travel head head full 5 axis.

Whats out there? Just trying to load up info because there is rumor of new machine??
