Trying to use the tool list in 2019 for lathe, it doesn't seem to support 3d tools. Rest of the tools show up fine, it just skips over the tools created with the new 3d tool option for lathe.

We ended up with the post guys modifying it so it puts an XY from the Top Plane in the initial positioning. Then a G234 XYZ from the TCPC plane. The G234 XY while numerically different then the top plane XY are still the same machine position so it accomplishes what we wanted.

Thanks to all who responded.

5m 11.941s adding up the times. 4m 46s if you go by the start/stop time stamps (since some processing is ran in parallel due to multi threading).

Physical movement? Yes both the X and Y are physically moving when the Z moves. It seems to position XY off of the G55 offset, then when G234 is called it repositions XY based off TCPC.

Don't see an edit button. But using the G254/G255 or leaving it default the XY go to the same location, then re-position when G234 is called. In the case of the first tool path used to Rough, it positions the tool over the trunnion approximately 6-7" away from where it starts cutting. The next program finishing the full blade doesn't have as big of a re position but still moves (~1" but it starts at the OD closer to A0 whereas the rough starts at the LE closer to A90). Haven't moved on to the other programs yet as I'm working on some surface finish issues so been running these 2 programs primarily. But I'm sure they'll have the same initial positioning issues.

I guess I can only respond a few times per day, with a new account. As the reply window was missing for 24hrs.

I could have been more clear and used better phrasing. I was referring to being on the machine, not in Mastercam.  If you call up a X/Y position, when rotated, without DWO active, the X/Y position will not be using the calculated/adjusted work offset on the machine at Axxx.xxx Cxxx.xxx . It will be from your work offset at A0/C0. If you rotate, call up DWO and then your ref point, it will be what you see in Mastercam (retaliative to your T/C plane).  

In Mastercam using a Haas DWO/TCPC post, if you program from the top of your part with a single offset and multiple planes, the program will be the same if you have a 2" or 20" tall fixture. The simulation will be different because of your change in fixture height, just as the machine motion will be different. But, the actual code will be the same as DWO/TCPC is handling the relationship change. The problem occurs when the initial position does not use DWO, there is no way to account for the relationship between the COR and the work offset on the initial move before TCPC. 

The second program should not be used as it is calling a rotation when DWO is being used.  How much movement are you seeing on the first, are you seeing physical movement? 

 

 

Physical movement? Yes both the X and Y are physically moving when the Z moves. It seems to position XY off of the G55 offset, then when G234 is called it repositions XY based off TCPC.

Brian,

 

Did you buy a post or create one? If you created one are the XYZ coordinates rotating with the part?

 

I use this format

We purchased a post.

Outside of the initial positioning the rest of the tool path seems to run correctly.

I appreciate the responses so far. I'll admit I haven't tried too much on the programming side for a solution, but the few things I did try with regards to where I approach from have resulted in Over Travel alarms.

As for Brian's advice I've tried both the following:

Both still do XYZ movements when the G234 is called

We're a small shop that does Impeller work. We got a new VF2 TR160 machine that came with TCPC/DWO. None here are familiar with it and we're in the process of getting our post finalized. There's been some back and forth as we're learning we have to discard some of our old practices (G93 etc).

Essentially we're on one last hang up. We like to position XYAC before doing anything with Z. Here's a snippet of some GCode

I hand modified the G234 H13 to be below the /M08 (We also want coolant on before Z moves as there is a delay and if not it will start cutting before coolant actually flows). By default in the current post it's on the same line as the G00 G90 G55.

The problem is the X-1.7192 Y2.1279 are not accurate. They are based off the G234 but since it hasn't been called yet the machine moves the tool somewhere over the trunnion (for this program). Then when the G234 is called it does a 3 axis positioning to the proper place. Bringing Z down close to the trunnion/part while XY are mvoing. Which is what we want to avoid, only Z should move after everything else is initially positioned. If I leave the post default with the G234 on the same line as the other 4, Z comes down near the tool setter, trunnion, and part as it wraps around. In this case it's all avoided, but I'm not sure how it'll be with a smaller part that requires Z to move down more etc. It's something we'd just like to not have to worry about.

If I try to move the G234 H13 (leaving Z where it's at) above the G00 G90 G55, or even on the same line just with Z by itself still I get a Y Axis over travel alarm.

I have the post people working on this too but it's been slow and the few responses I've got are leading me to believe they can't do what we want.
