    Vacuum table setup question...

    Well if you wanted to get real slick you tie and emergency shut off to the solenoid and when it looses vacuum you don't loose anything. I would think an isolation process would be better with a 3 way valve. I would use the machine to move the 3 way valve to one area and machine it keep all possible vacuum on the lot fo 12 parts. Once done the machine then moves the switch to the 2nd position to machine the next 12 and then rinse repeat for the last 12. Now you keep max vacuum isolated to 12 parts. Make a Ring and turn off the spindle and drive the tool into the ring with a hole and then just move the machine from position one to position two and then from two to three. Want tot think outside the box then do something like this and then should be good to go. Now if you use the emergency stop process then you shouldn't loose any parts and could still keep it running when thing are running good.
  3. Happy Monday, everyone. First, the setup: We use in-house designed custom acrylic vacuum fixtures to machine all of our plastic parts, a method that has worked near-perfectly for over 20 years. Every now and then, though, we have a troublesome job come through. The job we're running right now is a great example. It's a flat panel out of which we cut 12 pcs, and we run 3 panels per cycle. so, 3 x 12-ups. The rear (bottom) side of our vac fixtures have access grooves milled into them to allow vac to flow from the machine itself to the vac fixture. Then, on the top side of the fixture we have the actual part layout and corresponding vac hold-down grooves milled. So, basically, while the 12-up panels themselves are isolated from each other physically on the table, they all share the same bottom side vacuum access grooves...mainly because we only have one vac supply per machine so we just use one supply to feed all vac layouts. When one of the parts in any of the 12-up layouts shifts or loses vac hold, the most common result is the loss of 12 parts...and if the operator is tending to something else and doesn't notice it, we lose the entire 36 pc run. We've grown used to this and try to monitor that job more closely. This doesn't happen very often but it does happen, but I've finally grown sick of it so I had an idea... Now, for the question: I'd like to install some kind of solenoid in each of the 12-up layouts, with each solenoid running to a 3 port manifold that connects to the vac source. The purpose would be for any of the solenoids to detect a sudden loss of vacuum and shut immediately, thus mitigating the loss of parts to a minimum of 12, thus saving 24 of them. (Once one shifts, they all shift due to the nature of the layout, which really can't be changed.) So...does anyone have any experience with some kind of solenoid like this, and does anyone have a link or brand they would recommend? Yeah, I googled, and I've checked the usual MSC & McMaster, etc...but I'm not sure what I'm looking at when I find something that kinda aorts looks like what I want so I thought I'd check with some real people for their thoughts. Thank you for your time and patience.

    Mill-Turn Stock Model

    Using a Trunnion assembly currently in a I-200 and it is not supported in MT, but I am making it work. I feel your pain this was brought up back when I was doing this kind of stuff in X4. I was also part of that focus group funny since I rounded up the folks that went, but here we are still limping along to do MT type of work that is not standard bar stock type of work.

    Mill-Turn Stock Model

    The BIG issue is not every part in mill turn is round or even turned at all. I've cut for instance airfoils pre machined where there is no round stock to hold on to. Root and tip are odd shaped and impossible to put in a chuck.

    as a work around Brandon just make your Turned stock profile include enough geometry to cover the fixture, see image below. from a quick test this works well. Mayday submitted it to cnc it sounds like so maybe there will one day be a better way but i think this should do a nice job and isn't very difficult to draw the stock profile

    I will bring this issue up again with CNC. What's needed is the ability to load fixture models in each spindle, like Es***

    oh i see, i thought you were just looking at clamping on something that was already turned

    I'm clamping on a fixture with a smaller OD, not the full stock diameter.

    Mill-Turn Stock Model

    hi Brandon, the easiest thing to do in my opinion is create a profile that represents the Exact shape of your stock, then use Revolved stock for your stock setup, as long as your profile you select doesn't have stock on the end that was already cut it should clamp right where you need. Also if you turned the first side of that part in mastercam you can do a lathe stock preview to save the stock geometry or the turn profile if you dont feel like re-creating it. if none of this makes any sense what im trying to say is do it kindof like i did a stock flip in this video here https://fastechincorporated-my.sharepoint.com/:v:/g/personal/joshc_fastechinc_net/EeQzcaIJqGBKqXKRNrZhuu4B8RauXDgJZ4_JBHg7jWoL2A?e=6yjfQN
  11. Very noble of you. thank you
  12. You have been helpful, I have picked up a bit while working through this. My original logic addition to the post cured this behavior for this particular case, but, I have found that it does not eliminate the behavior entirely. It is showing up again in between some 5x Deburr ops as well, in spite of my "fix". Back to the mines...
  13. Well that is something completely different and needs to go back to the reseller so they can get it addressed. The mapping between the operations is not outputting correctly and they need to look into that section. This is what I like to have a file and information to see specifics and sorry I can't be of more assistance with this one.
  14. gcode

    .mcam to .sldprt

    In Solidworks check Tools/Options/Import and make sure "Import multiple bodies as parts" is checked I don't know if this will work with step files, but you should be using parasolid (X_T or X_B) anyway Both SW and MC run on the NX Parasolid kernel so performance and model integrity is much better than you get using step files You may have to adjust your parasolid versions so they are the same in Mastercam and SolidWorks This will change with the version of Mastercam and Solidworks you are using
  15. You are correct, CYCLE800 is working as it should, and the calls are reflecting my inputs properly. For the sake of this conversation, ignore Ops 3 and 4. Just look at the first 2 ops and the resulting code from posting them. - Operations 1 and 2 are on the same plane. - Cycle800 rotates to the correct plane at the start of machining (prior to op1). - Cycle800 cancels in the correct place (after the second op). The problem comes in between these two operations. Look closely at the code that is output. I trimmed down the image from my first post to show area of focus... Here is the sequence of events... - Cycle800 is called and everything is rotated in preparation for machining - Operation #1 runs correctly, including the programmed retract to the Z11.480 clearance value at the end of operation - Operation #2 comment is posted - Tool offset is called (for no apparent reason, there has been no change, but this is no big deal) - The next three lines of code are the problem... - X.011815 (<-This is correct) Y-11.48 (<- This is incorrect. 11.48 is the current Z value) - Z-.568493 (<- This is incorrect. The Z is already in position, no call is necessary. Also, this is the correct value for the Y axis, not Z) - Y-.568493 Z10.375 (<- Here is where the post finally gathers its wits and spits out the correct values, which would of course be too late if you were to run this code.) - From here on, everything runs as it should/as is expected...

    .mcam to .sldprt

    Is there a way (or format) in which I can save a model with multiple parts (an assembly) so that it is readable by Solidworks as an assembly. When I save as a .step file or .iges file SW treats it as a part, not an assembly. I am trying to bridge a gap for operators on the floor to be able to look at assemblies I have created in Mastercam. But also to dimension and take apart the assembly to see how it fits together. The operators currently use eDrawings to view assemblies and parts created in SW. Any ideas would be helpful...
  17. I looked at it and on 2 operations you have mi1 as Zero, but then on OP3 you have it was 1. According to the post in this section you will get different behavior. # Misc. Integers: # # mi1 - CYCLE800 Retract Method # 0 = No Retract # 1 = Retract Z # 2 = Retract Z, then XY # 4 = Retract MAX along tool vector # 5 = Retract incremental distance along tool vector. See mr1. This is a new flavor or post out of CNC Software and it will take some time to look through it and see what could be creating the issue were were describing. I see the CYCLE800() for cancel working and the CYCLE800(,,,,,,,,,,,,,) for calling DWO working as I think it should. Pay very close attention to the difference between each DWO call they are different which is important and looks correct. One is a 45 degrees and one is a 90 degrees. You have different rotations going on and CYCLE800 for each position must be called. Just search through the code using CYCLE800 as the search and you will see this flip flop back and forth through out the code. You have programmed a 45 degrees and then 90 degree move and the post is giving you what your want because of the way you programmed it. Where the planes are the same you are not getting redundant CYCLE800 calls, but where the plane changes you are. CYCLE800(0,"XF6300",200000,57,0,0,0,45,0,0,0,0,0,1,0,0) CYCLE800(0,"XF6300",200000,57,0,0,0,90,0,0,0,0,0,1,0,0) CYCLE800(0,"XF6300",200000,57,0,0,0,45,0,0,0,0,0,1,0,0) CYCLE800(0,"XF6300",200000,57,0,0,0,90,0,0,0,0,0,1,0,0) CYCLE800(0,"XF6300",200000,57,0,0,0,45,0,0,0,0,0,1,0,0) CYCLE800(0,"XF6300",200000,57,0,0,0,90,0,0,0,0,0,1,0,0) Please explain why you think you shouldn't be getting this output since everything I understand and know about CYCLE800 looks correct and should be doing what you are seeing.

    Looking for suggestions

    Either one will work for me. I am really excited about this, it's a functionality I haven't explored before.

    Looking for suggestions

    I ended up doing a bunch of moving prep, and visited with my son in the hospital on Sunday. I'll put some time aside this coming weekend (either Saturday the 30th, or Sunday the 31st), to do a live session. Is there one of those days which works better for you Zeke? I'm thinking around 1:00-2:00 PM, on either of those days...

    Mill-Turn Stock Model

    that's been my pet peeve since it was in conception. I've done a lot of mill turn with much of it mounted in main and sub spindle fixtures. I requesting this option since the focus group days at CNC. Not everything in a mill turn part comes from bar stock. So like Ron said, lie to it but not a good representation for simulation for sure.

    Retiring

    I just posted a link on the Job Opportunities forum. Please take a look. After 8 years at Albany Engineered Composites, It's time for me to retire. This job has been one of the most rewarding I've ever had.
  23. Thank you Colin. This is helpful information, but my problem is not with the retract moves within an operation, but rather in between two separate operations on the same tool plane. The post seems to be forgetting where it is at when transitioning between these two operations. I guess, chewing on this further, it is not actually forgetting where it is, but rather it is deactivating, and then reactivating, the TWP. When this occurs, even though no moves have been output, the XYZ coordinates have technically changed, which the post then interprets as requiring a position call. "Has your position changed?" "Well, I haven't moved, but I am technically in another location." ------------------ I trimmed down my mcam file and output a Z2G if anyone wants to take a peak... shrunk.ZIP

  25. I have done that I know I just want to clearify that I only have HLE products at home and I have to test at work okay, I didn't know that these VS templates / projects are the "new" way, I know that C and C# are different worlds too I think I will contact you for automatic toolpaths in an later state of learning, thanks
  26. Hello all I am trying to use Circle Segment Cutter (Barrel End Mill, Taper Form) with Multi-axis tool paths. I am having issues with Multi-axis Machining Geometries Offset (As shown in picture). Its not doing calculation. I previously used ball end mills, worked just fine. If someone can help me out pl. Thank you all.
