Mazak Variaxis / Inverse Time

[CJep]

Does anyone have experience with the Mazak Variaxis and inverse time multiaxis toolpaths?

 

The toolpath visually looks as if it is dwelling between moves.

[robk]

No problems here. Make sure your A and C axis are not clamped if doing 5 axis work.

Here is a sample code from our Variaxis 730;

Rob,

 

Yes, G43/G46 are there in the prep codes (we're using the InHouse post)

 

I'm currently looking for info using G43.4 / G43.5 and how it works with the Mazak Variaxis.

 

Have you used G61.1 with 5 axis toolpaths?

 

Inverse time has been used on this machine before but with larger parts.

I don't recall ever using G61.1 with 5x paths, but I may be wrong.

I have been corrected in the past that G61.1 and G54.2 could be used together even though the manual says they can't.

I have never used G43.4/G43.5 on our Variaxis (even though we have the option), but it is the only way I fly on our integrexs'. I am interested how many people do use TCP on their Variaxis though.

No small parts here.

[Ron Branch @ Verisurf]

Check the post and see if it set-up to use 5 places before the decimal for inverse time and also if the machine will support 5 places before the decimal. If the machine will and the post is not then get it changed and try that. On smaller parts where the machine has high feed rates the inverse time factor needs to go to higher numbers in the past I have seen post only go to 999 when they should have gone to 99999. That may not be the case here, but never hurts to have things to look at. G43.4 or .5 is the only way to go with 5 axis on Mazaks since it allows you to have one gauge length for programming and allows Mazatrol to compensate for all axis moves in the control for different length tools. Be real careful thought that when going home you turn it off or when doing drastic indexes. In those cases I like to use a curve 5 axis toolpath when I keep control of the machine using code verses allowing it to deicde how to to index positions.

 

HTH

[CJep]

Ron,

Yes, it's max is 4 places, I just posted the code and it stops at F1000 for inverse feed.

[Ron Branch @ Verisurf]

I think it should go to 9999 not 1000 so might get with In-House and see if there is a machine definition setting that needs to be changed or a post setting if the machine will allow up to 9999 values for inverse time.

 

HTH

[CJep]

^^^Post is on the way, sent it as you were writing.

 

Thanks Rob & Ron

 

Do you one of you guys have a copy of the Mazak programming manual in pdf you would be willing to share?

[Joe788]

CJep, 1000 is very slow if you're close to the center of rotation. As you can see on Rob's sample from his 730, he gets up to around 2500, and he's 10 inches from the center of rotation.

 

What model Variaxis is this, and do you have a Matrix or Fusion control?

[CJep]

It's a Matrix control, the post has already been sent up to InHouse for the inverse feed edit

[mayday]

you should get 9999 or 10000 for inverse

 

snipit from our E420 Intgrex using G43.4. this is a very small port toolpath in a 4 mm hole. We always use G43.4

I use G05 P2/G05 P0 im running surfacing/multiaxis with or without inverse. helps with the stuttering. on this it has to be brought in after the G01 and Canceled before a G00. you cant have more then 3 lines of rapid command.

 

only thing with this is you cant use G54.2.

[CJep]

we be rocking now

 

Had to change the minimum inverse feed rate to 10000 in the general machine parameters of the machine def mgr.

Have you tried running it yet? Did it fly right through it?

 

Also, I'm fascinated that the In House post doesn't spit out an A and C location on that first line. Was there an A and C move on the line immediately before it that you clipped?
