Unwanted rapid retracts with 3d flowline
Pgreenlaw replied to Pgreenlaw's topic in Machining, Tools, Cutting & Probing
This is all great info that I truly appreciate and will add to my programming notes for the future. Thank you again for the second response. I was slightly concerned with the small loops but everything looks great in the simulation and I think these paths will give us a great looking part and eliminate a lot of hand deburring that I am trying to avoid:) -
Unwanted rapid retracts with 3d flowline
Pgreenlaw replied to Pgreenlaw's topic in Machining, Tools, Cutting & Probing
Thank you very much for this suggestion. I had played with the gap settings using the "% of stepover" and not getting the results I wanted, switch from % of step over to "gap size" and follow surfaces method and I now have exactly what I wanted. Thank you again!! -
Are there any tricks to getting rid of the retracts when using the 3d flowline toolpath? Currently driving off of surfaces made from the solid model chamfers. I am assuming the retracts are because the surfaces are individual surfaces instead of one flowing surface? I am not experienced with modifying surfaces, but it seems that if I was able to join all of these surfaces I could create a smoother path? Looking for any tips or tricks to expand my 3dmilling experience.

worst case scenario you can post it out like that and just rearrange your XY absolute positioning to accommodate what you want to do with your incremental sub program?

We just got a new Doosan NHP5000 installed at our shop. We are interested in adding vacuum fixture air supply ports that each pallet can access when we run vacuum fixtures. In a previous shop I have seen this accomplished by drilling the center pallet changer post thru on top of the machine, installing air swivel connection at this point, and then running a T splitter with an air fitting facing each pallet. I liked this style as it allowed air to be hooked up and the machine could run and pallet change uninterrupted. Looking for any other ideas or tips/tricks if anyone has some?

Change start points

We have worked with this customer on changing/tweaking features before... last time I did that I had about a 1.5 week delay while they updated the solid on their end and created a new rev so there were no issues at incoming inspection. Machine sat too long waiting on customer approval/updates, jobs behind that had to get pushed back, etc. I am taking this opportunity to avoid the delays on their end with a new rev and trying to gain some programming experience at the same time:) Thank you for taking the time to reply, all feedback is greatly appreciated on these forums.

I was able to find it by right-clicking. Thank you very much, sir. I have never even seen or heard of that toolpath but it worked perfectly for what I am wanting to do. Thanks again for learnin' me sumthin' new:)

I have a part that has been challenging me with my programming skills from start to finish. I am almost complete with the program and looking for any advice on finishing/continuing the inside .062 rads down the corner of this "ramp". I finish the majority of the ramp surface with a .375 ball end mill using a scallop tool path. I will have to finish with a long-reach reduced shank (1.5") .125 ball end mill. I have played with a few toolpaths but am not getting results I am happy with. Any help or suggestions are greatly appreciated! PS. the ramps have no finish call out, will not be exposed to the end customer, and provide a pathway for air flow only. Our customer is more concerned with reduced cycle time and cost per part when it comes to these features.

.1875 HOLE 8 INCHES DEEP IN ALUMINUM
Pgreenlaw replied to Pgreenlaw's topic in Machining, Tools, Cutting & Probing
Thanks for the replies! I decided not to drill a bunch of small deep holes and ended up going with a vacuum “pocket” on the backside of the fixture. Covered with a .125 plate and sealed with an oring and 64 screws. Adds to the setup time but I like what I came up with instead -
.1875 HOLE 8 INCHES DEEP IN ALUMINUM
Pgreenlaw posted a topic in Machining, Tools, Cutting & Probing
I am fairly new to mill programming and looking for tips or techniques on making a custom deep hole drilling cycle in 6061 aluminum for a vacuum fixture. We have .187 high speed steel drills with 3" of flute and 10" overall length twist drills in the shop and I was hoping to get these holes done without ordering a special drill. Research (cnc cookbook . com) is telling me a normal twist drill CAN NOT drill this deep....does anyone agree/disagree with this?? I don't care how long the cycle takes, I am trying to go slow and avoid scrapping out a very large and expensive piece of aluminum. This is for a large vacuum fixture and I only need to drill these holes once and there is 4 holes total I need to drill. Any help is appreciated:) -
Alternative use for TSC...
Pgreenlaw replied to Dontech's topic in Machining, Tools, Cutting & Probing
Edit: sorry I read your question wrong. Disregard what I put below. CHECK OUT SPIN JET FROM ISCAR. USES TSC, NOT AIR. WE HAVE HAD A KIT IN THEW SHOP FOR YEARS AND NEVER HOOKED IT UP OR PLAYED WITH IT. HAS A BLUETOOTH DISPLAY THAT TELLS YOU RPM. SUPPOSEDLY CAPABLE UP TO 30,000 -
Vacuum table setup question...
Pgreenlaw replied to Dontech's topic in Machining, Tools, Cutting & Probing
https://store.piersonworkholding.com/vacuum-level-monitor.html PIERSON MAKES THIS WHICH CAN TIE INTO YOUR E-STOP/FEED HOLD CIRCUIT AND STOP MACHINE WHEN VACUUM DROPS BELOW A CERTAIN THRESHOLD, MAYBE THIS WOULD BE AN OPTION FOR YOU? -
Sorry to dig up an old thread but this is almost the exact situation at my current shop I am dealing with. we have 3 of the exact same model and control ES450's in our shop. 2 of them have the "type C' offset table that has 4 columns (H, H wear, D, and D wear) The last machine has the "type B" offset table with only 1 column of just basic offsets numbered 1-99 I have the same issue where if I give a program to a setup guy and he sets it up on the type B ES450 without altering all of his programmed D values, the machine will crash when it called up the tool length as its D offset and tries to make a -10" offset Does anyone know if the upgrade from type B to type C offset tables is something that can be done in house with a parameter change? Or do we need to get with FANUC?? All 3 machines are 1997-1998 Matsuura ES-450H models with Fanuc 18i-M controls which is why I was hoping it was a simple parameter change. thanks for any help or direction
