    That is how rough the grooves. The finish requirements force us to finish turn the grooves.

    Machine utilization

    Our bins are 3' * 5' * 3'. The issue isn't the size of the bins. It is that the turnings like to pile up in a straight cylinder. Our project to motorize the bins to have them move back and forth slowly is designed to spread the chips evenly across the 5' length of the bin.

    Machine utilization

    We actually have a pretty good handle on chip control. Roughing is not an issue, we get good chip breakage during roughing. The only thing we struggle with is finishing on the serpentine grooves. We rough them with a custom profile mill to avoid stringy chips, but it is not good enough finish. It is a bit of slow finish feed rate combined with a 35 deg tool going into a 40 deg v to finish. In the bottom we end up cutting a wide flat ribbon of material as the tool rounds the root into the opposite wall. We have made our own custom holder that aim 1000 psi coolant with the nozzle .5" from the tool tip. We use PCD inserts with laser cut chip breakers. They work great for finishing the rest of the part. At .002" IPR feed the chips look like little bits of fuzz. It is also a little bit of piling issue in the chip bin. We have 1.6 cubic YD. bins and the chips pile up in tower while the rest of the bin is empty. With the moving bin it will spread the chips out across the bin.

    We looked at chip shredders but they are pretty expensive, we couldn't find one for less than $50k. We figured out the moving bin should get us 12-16 hours of unattended running on our more stringy chip producing parts. That's enough to cover overnights. On other parts we no routinely get 16+ hours of unattended running.

    Machine utilization

    With 16 station turrets in the LT we don't do any tooling changes. We have enough parts that can be run with the same tools. Sometimes we use an endmill to open up a hole, etc. We have Schunk ROTA quick change chucks in all our lathes. A changeover that needs chucks jaws, robot jaws, and different material trays takes about 20-30 minutes. The reason the LT is lower on cycletime is we can't run it all night without filling the chip bin to fast and sucking chips back into the machine. We are working on building a motorized bin that will move back and forth to spread chips out. Of our 450+ parts numbers, all but <20 are aluminum. We outsource all the non-aluminum parts. It's not worth changing over tooling for. We run PCD finishing tools so they last for months. Everything else we run insert style carbide tools so no tool touch off is required. We do use some carbide endmill, but we have stops in the holders.
  7. Just pulled data from our tracking software. This is in cycle for our three lathes (Okuma Multus B300, B250, LT3000) since Jan 1, based on 24/7 production. Not too bad considering we do multiple setups in each machine everyday. We try to hold no more than 2-4 weeks inventory. We have about 300 part numbers that go through these three machines in monthly quantities ranging from 10 pcs to 500 pcs. Also, we only run one shift a day and minimal weekend times. We run a few different short 10-20 piece runs during the day and switch to longer running parts for overnight unattended. We also have a new Okuma U3000 that we are building the robot cell now. The auto door option for the machine is not scheduled to be delivered until mid next month. Once that is installed that machine will go into full production as well. That should give us a break on weekend demand from the machines, at least until we develop more products to sell.
  8. You will need to do XY calibration as well. The macros check to see that there is calibration data. Even in a Z axis probe cycle they use the calibration for positioning adjustment for probe tip runout.
  9. Not in his case because the #139 value was cleared upon leaving the sub/macro program and he had the #500=#139 in the main program.
  10. .625 IC 55 deg is not a very popular insert size. Not many people need one that big. You might be able to get a custom made.
  11. You might not necessarily be able to see it. The PMC can process data way faster than it can update the HMI display.
  12. It has been a long time since i have worked on a Fanuc, but two things are coming to mind. First IIRC there is a parameter that makes the control retain #100+ variables after reset/M30. Second, it could be losing the values after the jump out of the 9843 program to the main. Try putting the #500=#139 at the end of the 9843 macro. Or look inside there to make sure it is not being cleared in there.
  13. The pallet changer for our Okuma Genos M460-5ax showed up this morning. Some assembly required....

    HSM pack

    Years ago, a version or two before Mastercam came out with Dynamic we had it where I was working at the time. The HSM toolpaths were awesome. We also saw that the regular 3D toolpaths calculated faster and gave us better finish than Mastercams 3d Toolpaths. A few Mastercam versions later the difference was minimal.

    Okuma Schedule, Program Source alarm 2612?

    That alarm is saying it can't find the file. It would be a different alarm if it were a memory issue.
