25+ years ago in my 3 axis days I would of sided with the operator, or at least sided with the people saying it does not make any difference. Now, with functions like TWP and TCPC being the norm rather than the outlier I would strongly insist people to adjust wear offsets and leave the commons alone. On our Toyoda bridge mill with a right angle head the macros write values to the common offsets depending on the orientation of the head. Not sure why Toyoda/Wele decided on that method, but it is effective. It did throw the operator for a loop, he came from a large 3 axis vertical and had the using common offsets method so long it was etched into muscle memory.

We did. We had no intention of collecting. We knew the bill would get to the CEO's Office though, and the bill created the desired effect. From then on when we asked them "...don't ask me stupid simple questions like that..." questions, they are FAR less flippant with their answers. The embarrassment that situation created was pretty epic. I knew with absolute certainty the problem was that, but the setup guy vehemently denied putting any values in there but he was the ONLY person running that machine. When I ask a question, it's not to waste time, even though it may feel like it. It is not to deflect anything. It is to get to the bottom of the issue as quickly as possible so the machine can get running again. More often that not, solutions are someone forgot something relatively simple. It's not a problem. I forget the simple stuff too from time to time. It's part of the gig.

Is using Active WCS checked when using Machine Sim?

If they have to be mitered, the angle is a funny 77 something degrees on the corners. Years ago, we had a tool ground just for this. But that said, flowline, waterline, contour with angle, 2D swept all will work

Hello, I am learning Mastercam and I can't figure out why/how to locate the workpiece, fixture and stock in the simulator or machine simulation. From all the tutorials I have watched, and from experience using a default machine I had the impression that everything sort of automatically locates. This leads me to believe that the issue lies with how I built my machine which is a 2012 Haas VF3ss with a similar age TRT100 trunnion. Could this be attributed to a misuse of the dynamic elements: workpiece spindle revolving group versus single workpiece set? That is a difference I noticed between different machine building tutorials. The trunnion is also 90 degrees out of the standard ~180 degree limits I specified. It kind of looks like the fixture may be located correctly with the trunnion in the wrong position but in previous attempts when the trunnion was in the correct position the fixture was not located correctly. As you can see in the pictures I have not set up holders yet.

My shocked face

If you ask for a file or a picture it is okay. I do it and I am racist against Asian's? Gotcha the old don't do as I say and do and then call someone something because they use reasonable methods to get an understanding of a problem just like you are doing here? People call me the crazy person in the room funny when others do the same exact things and it is totally acceptable.

Ended up having to use G112 to convert the X and Y moves to X and C moves. That took the "stuttering" out of the C axis. Still not sure why it cannot figure out X and Y moves from the face of the part.

Are there any pictures to see? surface finish contour should be ok...

Hi all I have a LU-15 okuma with OSP 7000i but am struggling to write an internal threading program for M36. & also M42 any help on this be greatly appreciated as I know there is a lot of Smart cookies on this site cheers Matt

Change the overall length of your tool in your program and re-post. Best way to check is to use a known gauge on the machine to check for these type of issues. Make a block with different angles and then do a shim check at each angle to ensure the changes you have made are exactly what you were thinking before cutting the part.

Thanks for the call out, looks like Dylan beat me to it Been onsite a bunch lately and haven't had time to check the forum for a few days!

Pragmatically, if you've programmed your part to what you believe the center of rotation was and then find out that it's not the real center of rotation, if you don't have TCPC/Work Correction, I would move the plane (or model) in your CAM system to the Real center of rotation and repost. You can hack around trying to do individual work offset corrections, but if you're using simultaneous 5 axis motion, they'll all be wrong. Moving the model in CAM will ensure that no matter what you do, it'll be correct without fiddling. That's why TCPC is worth what they charge for it!

You'll need to adjust either your work offset or your tool length offset.... best I can recall anyway since i never program COR anymore.

Likely best to get your Applications Engineer in to help configure the machine correctly.

Thank you for your comments, if I don't have this option enabled, what can I do to adjust it? I'm out by +0.025"

Worked for me. Thank you!

Yeah why I get work is this very reason. At least 20 different times I have had to go in and help dial in machines after this was done.

Break it up on these machine is standard practice. X Y and C should be possible with the correct post and toolpath. 3 Axis toolpath probably not would need to use a 5 Axis toolpath set to a 4 Axis output and that should give you what you need, but will need to have a 5 Axis License to do it.

I hope you billed them driving time to and from your 30 second service call

At my old place we had to call a service guy because the machine wouldn't come out of emergency stop There was a pile of boxes that had fallen over and pushed it in by the tool changer magazine behind the machine

Thanks for your sharing. This is what I am looking for.

I wish I could remove the common offset from the offset list. I had to drive 3 hours on a Saturday because "..we don't know what is wrong with the machine... no there isn't ANYTHING in the common offset...". Emphasis theirs. 30 seconds after I arrive, problem fixed and I'm headed back home. Uncool.

If FANUC options are installed in the field, the FANUC Engineer will not configure them. He or She will only turn them on. It is up to your builder/dealer to configure them. Why is that you ask? Ask the guy at Haas that decided to call ANY single rotary axis "B" axis... he's got a part time gig at a few machine tool builders... I'm sure of it.

Machine - Okuma LB3000 MYW Y-axis +2.76” / -1.77” We have a part that can be machined complete using XC moves, but XY moves would be more rigid and precise. Mastercam does not output X+Y+C moves as far as I know. Aside from breaking up the toolpath into multiple sections, is there a way to limit how far Y tries to go plus and minus? Any suggestions are appreciated. Thank you
