solidworks model of PocketNC

[Bryanbdp p]

I've been working on a solidworks model of the PocketNC to help with positioning parts and creating fixtures.
The file is not designed to be an exact copy of the machine, merely a close representation with the proper dimensions and travels.
The problem I'm running into, has to do with travel limits. If I put a limit on X travel, Z won't work (is fixed).
Maybe someone here can tell me what I'm doing wrong, or how to work around the issue.
These travel limits always seem to give me trouble, unless I'm using just one on the assembly.

I have A & B working OK, but not Y. I have X working OK, but not Z...
Thanks,
Bryan

It's a great idea. Are you using dynamic simulation? I know Mastercam has an entire tool patch simulator based on the kinematics for a machine. We set up a couple machines at work and it's really nice. While I use Solidworks everyday I've yet to use their dynamic simulation module. I know Fusion has some basic kinematics for assemblies. I might import your models in to Fusion and apply them as I pretty much know how to set them up. I do agree knowing the actual limits with respect to fixtures and work holding would be an advantage. I actually nicked my B outer table bezel with a tool once as it rotated and I didn't even realize it could crash.

I tried to access the Dropbox file but didn't have success, but I'm at work. I'll try it from home.

BTW are you using Fusion 360 for CAM? It would be pretty good to get your model set working with it.

Hey welcome to the forums!

That's a pretty cool idea! In a solidworks assembly, you can choose, advanced mates -> distance mate, and set the minimum and maximum extents to get the model to behave as expected.

Hi. I was just trying to assemble a reasonable model, with axis's that move. My issue is with the distance mates, if I use more than one something else locks up.
I've had this problem with other models as well. Very frustrating. I haven't tried to do any simulations, I'm stuck while building the model because parts of it stop moving when I think they should.

Haven't learned MasterCam yet, but I guess it's time. We're partners with MasterCam to promote a Veteran's program, and also a large Makerspace project here in CT.
So, it's time to dive in I guess, if Mastercam has the built in capability to simulate machines, probably a lot easier than building a model.

Also, Mastercam has finished the post processor for the PocketNC. They are just trying to decide how to handle pricing issues, since the cost of the PocketNC is probably comparable to a typical post.

Were you guys able to download the link? I'll repost it here just in case.

Hey Bryan,

We have been working on getting a Post processor setup for Mastercam and hope to have it out soon. I will post a link on this thread when it comes out for anyone that would like to use it.

Sounds like you've already done most of the work of getting the machine modeled, but you can also find CAD files of the machine here.

[Randy Kopf]

Actually the models from Pocket NC would help to see the math. I used them to view the machine more like a traditional NC.

I had imported them in and did some checks previously all to set up a Desk Proto post processor.

But I think I throw the Fusion 360 Assembly Contact sets with Drive Joints and perhaps Sliders into the mix. It could be pretty handy to see a part on a fixture and how much clearance we have when rotated in various orientations.

Back to the original point real quick,

I remember HSMworks having a feature for full machine simulation inside solidworks (more info: http://www.autodesk.com/products/cam/features/hsmworks/advanced-simulation-tools/milling-machine-simulation ), so having the model in solidworks would be a great way to check for collision, since it is possible to hit the table with the spindle when A=0 and Y is negative. (I'm actually not sure what the minimum Y is without hitting the table, I'll have to experimentally find it later on or check the CAD!)

I'll try getting a machine simulation working inside solidworks and let you guys know if I have success!

Best,

Dear Bryan,

can you help me, why can't open the solidworks files ins solidworks 2013?
I try open from 7zip unzipped, local hard drive.

You made the files newer version?

Error message: "solidworks an error was encountered while trying to open your file".

Thanks!

Xander:

I nicked my table when going to A0 Y0.

And I got the mark to prove it haha.

Hi. I used solidworks 2016. thats probably the problem.
I've started learning Mastercam X9, I'm looking forward to doing a full machine simulation, which should be possible.

Thanks, works fine!
I don't have pocket nc mashine. Why create you the sw modell? The seller don't give a schematic modell about a mashine for cam simulators?
