Horizontal boring mill with “W” Axis

[Guest]

Is anybody programming a HBM with “W” axis out there? How do you handle the “W” axis part of it? I need to edit a post to support it on a Fanuc machine. Any samples or examples would be appreciated. Thanks in advance.

We have a couple of vertical gantries with a "W" axis. We used to have a W30. hardcoded into the post and the set-up man would modify it at the machine as needed. I tied it into the max travel output with an additional +20. Either will work for you.

We have a few HBM's here that also have the "W" thing going on. Ours are hard coded like John said at W-4 in the post. We also have a misc real set up so that we can change it if need be. We normally just leave it at -4 and let the operators take care of it though.

We have a lot of HBM's with "W" axis and we use a misc real value to define it. Just like Greg.

We have a Vertical machinging Center with a W! 2 really. "W" used to be hard coded till i got tired of that. I now use Misc. Real #1. works well

Mark I have seen it both ways and I personally like the Mi way better than hard coding, then again I like to know where and how everything is going and doing when I am posting code.

Ron:

 

So do you set the mi at each operation? Then out on the machine, do you set the W to the mi value and then set the tlo?

Marc,

 

We set the mi value at every operation and use a g-code in the machine that will position de "W" axis and then compensate for the value that the "W" is out. We then take the cutter comp (G43).

 

Hope that helps,

Where is the "W" when you touch off you tools?

[crazy^millman]

Marc the machines I have seen take the W in to account inside the control when using the W and cutter comp. So if you move the W 6 inches then the machine will adjust the Z inside of the machine to make the offsets work correct from what I can remember.

Marc,

 

Tool offsets and program fixtures are always taken at W0.

Hi guys, gonna bring this back from the dead. I'm trying to get my TOS Horizontal boring mill to work with MC. I need to get the machine to move "W" to 0.0 after the tool change. I can't figure out how to do this with misc int/ values.

Any help would be appreciated.

 

Thanks,

I just hard code a "W0" into the tolchange block

and another into the G28 home block and let the operator set it as needed

Concord,

 

Are you talking about a Toshiba machine with Tosnuc control?

 

If so we use this line to retract both the W and the z axis: G73 Z[V1203] W[V1204]

 

V1203 and V1204 are the values specified in the controller for the reference point #1. V1204 is equal to 0.

 

Hope this helps,

Martin,

It's a TOS WHQ13 with 40 tool changer and Heidenhein TNC530 control.

I'm pretty green when it comes to post mods and such.

I had 1 guy for awhile that got a "W" move put in that works but I want to understand how he did it in case I need to make changes down the road.

 

Thanks
