Mazak 630-5x

looking for a post that will output dynamic comp.

for a 5 axies machine when work piece not in the center of table, comp. when A-10. C0.

OH BOY!!!!

 

 

Warm it up guys

 

Have you tried you reseller?

you should read the forum rules quick

[dwsz71]

jmp's ready! Flame on dude!

 

Damn... 2k4 and finally a post! Whoa!

[crazy^millman]

Sure you got one the idea is to use it and config it for your machine then you should be ready to go. MPGEN5AX V9 and earlier and Generic 5 axis post for X.

Q. Does anyone have a post for a [insert machine or control name here]?

 

A. Ask this question as your first message here and you won't necessarily like the responses you receive. Look to your reseller to supply you with the proper post for your machine, or quote for the work that needs to be done.

 

If you have something and are looking for improvements, it's a reasonable request. Maybe tell us why the post you have needs improvement.

 

Perhaps try to participate a bit on the Forum before you go asking for something. Not unlike Habitat for Humanity, we value Sweat Equity here. Quid pro quo, Clarice.

 

You may also want to let everyone know your company name so that your Hotmail or Yahoo email account doesn't give everyone the impression that you aren't a licensed Mastercam user.

We have a Variaxis 630 5x Post with dynamic compensation. It cost us mucho grande $$$$$$$$$. If you want a free one ask post modification questions and I am sure someone can help tweak the generic fanuc 5x post to do the same thing. If you want one now, ring Inhouse solutions and write a cheque.

Once again my company have the variaxis1 post but the output is not up to par with the machine capability . If there is a Oz you first need to find the yellow brick road and so on............

thanks bruce

and yes your right with that quote.

First off that is NOT what you said in your previous posts, you specifically asked for a post. With that being said if you need modification that is probably doable.

 

Welcome to the forum

 

What is the problem with what your posting is outputting. What are you getting and what do you need?

[crazy^millman]

Yeah believe it or not we have all been there atleast once. I went to place that did not have a good post and I had ot figure out how to modify posts for a 5 axis all on my own did not know about the forum. I as well as others will gladly try to help you get things fixed but free posts espically for a 5 axis are not going to happen sorry if you think they should. I took the time to get myself out of the middle and so did others and if you want some help climbing that ladder out of the hole you been put in by someone's stupidity by not getting the post you need we will help you like I said.

 

Welcome to the Forum I am origanlly from Jacksonville where abouts in Florida are you?

[DC Gorn]

I am a fan of the mazak controllers but they have one weakness. In true 5 axis work they can only work using single predefined origin point. So any post you get is going to ask for the distance from that point to your MC origin on every WCS you have. As a general rule these custom posts are pricey and locked down by the Mastercam serial numbers.

 

Since you will need to know the distance away just shift your part in Mastercam that distance and your current post should work. I currently am running multi-part 5-axis production of medical parts lights out and all parts are programmed this way. Funny part is I have the high end post but with proven programs I want my operators to fix what’s wrong at the machine not just try to adjust the problem away.

So if we modify the post can it output what we need it to do. The type of work is a Injection

Molding plant. Dynamic comp. uses a G54.2 offset

trying to avoid setting work piece in the center of rotation every time is there any tech support that we can send for post modification.

sorry but did not mean any disrespect to anyone thanks for help.............................

[Bruce Caulley]

DC GORN, That is how most posts are initially written as it is less risky. If you have a pc fusion controller you can leave the G54 page 0,0,0,0,0 and instead set your datum using the G54.2 offset page. If you have your parameters set correctly the machine knows where the rotation point is and adjusts itself. We have 2 types of 5 axis mazaks here and both of the posts prompted for guageline lengths when we first bought them. We quickly worked out that that was doing things the hard way and changed it to suit the g54.2 method.

 

When I get into work I will post some code showing how the rotations work.

[DC Gorn]

Thanks Dave,,, I know Camaros Arent "cool" anymore but someones going to have to pry that car out of my cold dead hands.

 

I have not done Mazak I some time. I am currently using DMU evolutions and they use a G7 to set planes. I was told by someone who I thought knew what he was talking about that Mazak could do the same thing it 5 axis positioning but it could not do it is true 5 axis work. Maybe he was referring to 5 axis incremental moves. I will need to figure this out tho cause my company has Mazaks in the UK and we may transfer jobs from time to time.

[smokey_44]

Who says there not cool , They will always be Cool , did you see that there goin to re-release the older style Camaros again in the upcoming years ?

It works with simultaneous 5 axis paths too. Here is some code of a swarfing op.

Thanks. I assume you ar talking about Bruce from Mouldcam. I saw in a search that he has a Veri-Axis 630. We have a 730. I have the post pretty much dialed in as far as Dynamic comp on and off. I have even included the offset variables in them to eliminate the scary z moves in on and off. I just don't know how to force the post to make the c-axis move after an A-axis move. It wants to stay at the last C-axis move and calculate the XY output at that location. That is fine if you are programming from c/l of rotation. But we are not and in this case dynamic is not on.

I agre about the scary Z movements when dynamic kickcs in and cancels out. Always make sure you call up the G54.2P_ before calling up the TLO...

We have the (2) 730 5X with the new Matrix controlls on them. Those machines are awesome!!!

 

Renishaw just came up with the update to their inspection plus software to calculate the dynamic work offset without having to do the math @ the machine. (N-4013-0118.00)...

Sorry, but I can't help you with the post. I don't use mastercam.

DYNAMIC WORK OFFSETS

--------------------

 

Addition codes #5121 #5122 & #5123 are used within the software. These codes allow the software to

run in normal mode and dynamic mode.

 

This software can only be used in dynamic mode to measure component features and positions, it can

not be used to update work shifts when G54.2 is active.

 

To update the dynamic offsets parameter S5 (X & Y) & S12 will need to be used in calculations as

shown below.

 

Using this example should give you a figure in X & Y which is the difference between the centre

of table rotation in XY and the centre of the part in XY, these must be within a small amount

otherwise the control gives an alarm (I think it is 3mm). The Z is not controlled to the same

tolerance and can be quite big.
