Another positive to spindle through coolant is it increases your edge life and also helps with chip evacuation which becomes a factpor when you don't have a operator to blow the chips off the part as the chips build up on it. As for the price I don't think Doosan can't be beat but bare in mind the Fanuc controller is no where near as user friendly as the Haas control so the learning curve will be greater. Not sure what your lead time is for your first delivery but you should take that into account. First time you jam your tool changer you will know what I mean. On the Haas you press tool changer recovery button. It asks you a couple yes no questions and you are good to go. Doosan not quite as easy. when you have to run the machine through the tool change sequence.whether you do it from the manual panel at the back or through service mode and trigger it using m codes.

Spindle Through Coolant is the only way to go. I hate not having it limits me to the type of carbide drills I can use and in 60RC you don't want to be running HSS. Good luck though and welcome to the forum.

I did a similiar test but I used a smart phone and texting. Still not sure why I ended up with a cop at my front door handing me a restraint order.

How do you go about reworking a part made from a old revision then? I am just not a fan of deleting anything that was used to make a good part in the past for above mentioned reason. Say the new rev fails and they have to go back a rev now you are repeating the process again to get back where you started. If you are deadset keeping the old associated geometry then use the "Only display associated geometry" copy it to a new level and delete all other levels and bring in your new model. This is because when you imported the operations you didn't select "export operations geometry" when you exported your operations

Can you not just export the operations from rev A with export operation geometry selected and then reimport it into a new Rev B file with new model and keep both rev's of your part only programming the same operations once (or in your case all operations with the difference only being the 2 less holes that need to be altered). So if they ever go back to a previous rev you still have your original file.

I totally get your point and do agree with you. I have dealt with a lot worse owners than one that makes me walk to a adjacent building to use the washroom. There is no savings to this what this does is give my operators a excuse to go for a nice long walk. The down time this is producing is unreal. I run the shop here and am expected to be fiscally responsible for everything that comes through my department and work within a budget for tooling and shop supplies. I am also responsible for maintaining the machinery and equipment used in the foundary making parts for the machines and tooling for them. All that work doesn't show up on my monthly, partially because Managers at the other Plant don't want the revenue moving from their department to mine for the work I am doing for them. So my numbers never look at where they actually are due to the hours spent on internal work for the other plant and the other Plant looks like God's because they now how more efficient tooling and machines running in better condition then what they have in the past. That is the one thing here that bothers me the most because we are on pay + production bonuses. based on a percentage of profit after operating costs are factored in. Obviously if I am spending say 30% of the hours the machines are running doing internal work that I can't bill back for then the work I am doing for our paying customers never adds up because I only have 70% of the time to do 100% workload. So how do you make up the 30%. Well with overtime, but that creates another problem because my labour cost for OT is now 1.5 X wages. Now I can't bill back my customers the extra .5 because i wouldn't get the contracts someone without the second plant that they support won't have that as a financial hinderance. So the dilemna is getting owners to understand that I need to be able to bill my time for all work I do for the other plant but everytime that comes up in the boardroom the topic changes quickly by the managers of the other plant that know if this does work the way it should it will destroy their margin and bonuses.

But sometimes you have to pick your battles.

unfortanately no.

Have you thought about using G10 blocks and let the offsets be set in the program as opposed to on the control by the operator? You marry your tools to a holder creating a database of tool lengths is easy then use a doweled sub plate and your XYZ values will always be the same.

My shop was off site they moved us into a old warehouse on the property of our main plant. But the warehouse doesn't have running water and they don't want to pay for the plumbing or city permits to run the water. So their brainchild was capture rain water since we are on the west coast where it rains constantly. I suggested getting a 50 gallon drum fill it with water and put it on a rack so operators can premix in the shop into 5 gallon buckets and fill the coolant tanks that way. They think the cost of the angle iron to fab the rack would be a waste (Keep in mind our main plant is a foundary with over 100k tonnes of raw material at any time). So what we have been guys have been doing is throw a couple 5 gallon pails on a skid hop on the forklift and drive across our lot (which is a few acres) and fill them and bring them back. Ther thinking is drain the water into the drum from the gutter and then no operator ever has to refill it. Using the odor defense won't fly with them because they aren't the ones who will have to smell it. They don't see the costs associated with having each operator do this once every couple days to keep tanks full when one 50 gallon drum would last a couple weeks that you would have to fill once. Not sure what a Tevas is.

Upper management got the great idea to save on the water bill if we were to capture the rain water from the gutters store it in a bin to be used to mix coolant. I am just unsure if this is a good idea. Seems the ph balance of the untreated water could play a diverse effect with the chemicals of the coolant. Thoughts?

Have you checked the manufacturers website? Most have software that will generate the NC code based on the cutter you bought from them.

I think what Thad is trying to explain is if you create Operation libraries for a 1/2-13 tap you would have spot, tap drill , chamfer than tap. So use import to import all 4 of those "operation files" and drop and drag your geo into those not copy and paste a operation than grab a second, third forth tool. I do what Thad does workls like a charm especially if you can get your engineering department to standardize tap depths, cbore depths and stock for facing operations and so on.

I use Z0.0 For top of part but then when I flip the part to finish the thickness and the bottom Z0. goes to the bottom.

I just use a normal feed move with rapid retract step over and rerun at my finish X value. I try to keep my operators from touching offsets as much as possible. Program it in once prove it and it is there for ever.

Thank you I already knew the answer to this i needed these responses to help prove a point.

Does anyone here use U Drills to bore holes? Can it be done?

Yes and it is inside the range.

It is a 10" chuck set to 300 psi of pressure and Chuck clamp light is on yet somehow my part keeps pulling out.

I am sure the material is a bit bent. I think it is a combination of material a bit bent brand new spindle liner that needs to be worn in a bit and bar feeder alignment is out a bit because it has been cycling a lot better. My biggest issue is with the chuck clamp and unclamp switches. My reseller is telling me I should take them off the motor drill a hole through the sheet metal and put a magnet on them to trick the machine into thinking they are doing what they are supposed to. To me this sounds like a bad idea that could possibly kill someone if a operator forgets to close the chuck before he hits cycle start. Over riding these safety switches to me sounds like a major liability. We have a forge at work as well and the scope of our work is fasteners for industries such as hydro and trains to name a few. One job we do is a 3/4" FHCS at we form the head on the forge than we skim off the flash that is left over from the forge. This is less than a 1/16" on the diameter of the underside of the countersunk side of the head. We then skim cut the face. To load the part we use a machinist square set at a specific distance from the jaws My chuck clamp indicator on the control panel is lit and my chuck pressure is at 300psi.Somme how this part moved 3/8 of a inch. I know this isn't a program issue because it happened on the 400th piece. I also now it isn't operator error because i was standing over the operator as he loaded it and watching him very closely because most of my labour is underskilled and this is the first job he has ran on that machine. I also have the neck where you can see where the first cut took place and when I reset and tried to figure out what is going on I could see something had changed. So I also double checked my offsets and all is good. How much of a safety concern is this? or is there something here that I am missing?

Mr. M and Doug I have not forgotten about this I got it to run so I don't want to tinker with this thing until this order gets out. Right now I am manually loading a bar and pushing it to the z0. of my program and letting it run. It is grabbing another bar and continuing on. But my liners need to be opoened up because the bar feeder keeps getting stuck. Some material works other lengths don't. Is this a alignment issue or is it just because my liner is new my springs for the V channel arte new and strong and I just need to wear in a bit? Tell ya one thing though when I first got into cnc back in 95 the first one I ran was a okuma mill. I haven't had a okuma in front of me since. These things are beasts and so much fun to watch run. You guys sell a wicked product.

The LNS tech added this line but the Okuma techs erased it. I think this is what you mean. IF [VDIN[24] EQ 1] NLOAD All I am trying to do is so simple. If you could help me I would be so gratefull.The techs I am dealing with are doing their best but they all miss one step and it creates a storm.

I just got a new Okuma and Bar feeder powered up a month ago and still am not making chips. The support from my MTB has been a bit slow but I am not here to bitch about that. I want to know if one of you gurus can help me with the problem I have and tell me if this is a problem with the machine or a simple missing snippet of code or something in my setup My proximity switches that send the chuck closed signal seem to be messed up and way to sensitive. If I have set so when my bar stock clamps the signal works turn the spindle on start turning. Great. But if I don't have a bar in the bar feederr won't do a bar verification check to start because it is awaiting a chuck closed signal fromn the okuma that isn't registering because the switch is out of range. Set switch no part when part is clamped won't turn on. So I thought okay take a small piece of remninent shove it into the chuck get the bar feed ready hit start and go with a NBAR which works but everytime I get to this statement I get alarmed out To get remininent out I put this and it works grabs a fresh bar and loads it. NBAR G0 X20. Z20. M5 M84 M93 (Send push signal to barfeeder, wait for confirmation) M83 G4 P2.0 M01 Now that my part is loaded this is where I alarm out. NAT01 G50 IF [VWKCC[1] EQ VWKCS[120]] GOTO NEND (CHECKS TO SEE IN MAX PARTS HAS BEEN REACHED) I don't know what that statement should be and my techs don't either so I am completely hooped. If I change that to IF [VWKCC[1] NE VWKCS[1]] GOTO NEND (CHECKS TO SEE IN MAX PARTS HAS BEEN REACHED) It will run but to do that I have to physically push a bar down my spindle bore before I can press cycle start which I don't think I should have to do.
