Ref Point Glitch? 4th axis vertical

[BK]

Okay Gurus,

 

I am using the mpmaster post and doing some 4th axis work on a vertical. I have been using the "Ref Point" option for a safe tool change point. The strange thing is that on all of the ops I have only checked the "X" axis box, nothing else.

Here's the hitch, I have about 3 ops (drilling) that also posted a Z axis move on the ops using this tool change move. The Z axis value it is posting seems to be the drilling target depth.

Anyway it makes for an interesting tool change move when it moves X-6.0 and then oh say Z-4.0 on the same line.

Has anyone else noticed this issue and if so is there a workaround or fix?

The edit common parameters thing doesn't work on this thing either.

 

To get rid of the problem I had to give it a Z clear value, then un-check it and then it seems to post out right.

 

The real strange thing is how the mucked up Z values got into the un-checked and unused registers in the first place!

 

Thanks in advance,

Bob

I haven't noticed that, but I have noticed that drill cycles don't pick up the WCS you manually forced in WCS.

 

'Rekd teh damn the drill cycles, damn them to hell!

+1 on that from Rekd. No matter then psot have seen where you always need to do that. I also use clerance when doing 4th axis in addition to any ref point if using one if I have the travel on the machine to allow clerance. i have also noticed when using mpmaster and doing 4th axis moves it will add an extra z move in there. I figured out in the post where and why it was doing thta and took it out. I cant remember exactly what I did but it only took a couple tries and I had it doing good.

Thanks for the info. I still can't figure out why it would "pick up" some weird Z value (even though they are "grayed out" in the Ref Box). I never used anything but X when defining the Ref Point.

 

I have noticed that if all ops are programmed for c/l of rotation and only use 1 work offset that the post forces out an XYA rapid move when indexing, then a Z position move after that. When I gave each index position a wo it posts out XYZA rapid moves WHHHEEE!!! It's not a bad thing since Z zero is at the c/l of rotation.

Wel Bk when doing 4th axis stuff in Mastercam I have found you need to rememeber which view you are using to keep x pointed in the right direction as if you were looking at that surface as if it were in a top view look. If you look at the back and really pay attention to x it is facing the wrong direction so you then need to rotate it so x is going in the right direction this could possbile be what you are seeing also. I always use the center of rotation for origin and if not you will compound any clereance and retract moves.

Thanks Crazy Millman,

This deal is just on a vertical with a 4th on it so it's not too confusing. I know what you mean about getting your sense of direction outta whack when working on a horizontal type deal.

Origin is at the c/l of rotation.

I also wish MC would give you the angle of rotation instead of "The Matrix" deal when you click the info button of your named view.

Is there still a drag strip there in Carlsbad?

Just wonderin

I totally agree with this.

Also when backplatting,I wish it would give the "A" rotation in verbose mode.

Yes would be nice to see all the angle repsented in Varbose. I like the way it looks and works just be nice to see the angles.
