Care to Share Settings?

What are your filter settings for 3D Machining?

 

My settings are for a 2010 Haas VM-6 VNC.

 

If we all compare our settings we can all make the most of our machines.

It all depends on what I'm doing. I have one project I set my total tolerance to .00005 while others I can leave at .001. Size, tolerance and the part feature its self all factor in.

Like Benk I program so many different machines just comes down to the part and material as to what I will use.

Jason,

 

Do you have the high speed machining option? If so, I wouldn't mind some advice in that area. I hope to use my 200 hour trial period soon but want to make sure I have a few things figured out first to best utilize the trial. Toolpath filtering is one of the things that I would like to get a handle on.

Guys,

Here is what I found. Look at Jason's Settings.

Set the cut tolerance all the way to the right. Don't change anything else in the tolerance settings

Set the federate to 300 ipm, and run it high off the part. Watch the machine reaction. Its easier to see at a high federate. See if the machine jerks, and /or slows down a lot.

I found this works on several surface tool paths. I have not tried it on the newer high feed paths !

 

If you see issues, set the tolerance higher and lower, and see the results. This is a place to start.

Thanks for your input, Machineguy.

Thad,

The High Speed option is cheap. Get it turned on.

And since you are in trial mode, Leave the setting off till you need it. With the machine on and the trial option on it will keep counting down, so keep it off till you need it.

Run a surface path with it off, and do it again with it on. When you get a path dialed in, then show the boss both sides. There is a big difference from off to on!

What is the setting code to look for to see if it is actually on?

[Machineguy]

There will be a "0T" for trial off

When you change the setting it will say "1T" for on. You can change the setting anytime, but when its on, it is using the machine on timer as a countdown, not spindle time !!!!!

 

Haas did it this way so you can try before you buy, with 200 hours to use.

Its parameter 315, halfway down the screen.

 

That's parameter button,

type 315 on the keypad, hit the down arrow.

[Thad]

It's $2600 for my machine, per the Haas website.

Cheap

Is the G187 E.??? required or optional?

[Machineguy]

You can use it . It's designed to slow down in the corners. My post has it in the misc values. The machine is normally set to P2, which is medium. That's in the settings on the machine.

To override it I turn on the setting of G187 = 1. Then I set the P value from 1 to 3.

For fast roughing I set it to 1. A setting of 3 really slows down the machine in the corners. Its good for the finish pass in highly countered pockets.

My post is the" Haas VMC 4AX".

I turned on the trial this morning. I have a small 2" X 2" area with some form on it (mainly just a flat angle) and cut 30% off the run time. Nice!

 

Thad

[Machineguy]

Glad that worked for you. Now, get the boss to see the difference in speed savings and finish.

I would suggest not outputting arcs in the XZ or YZ plane with a Haas.

 

 

See the results below.

[Machineguy]

Glenn,

 

What year and model of Haas?

 

Machineguy

[Glenn Bouman]

I have seen this on a brand new model and on a 1998 model.

On a horizontal Haas the problem occurs in the XY plane, maybe the counter balance is not calibrated correctly.

[Thad]

Thanks for the tip, Glenn.

What settings would i want if all i need is the shortest nc code when i post, i had this setting in X6 and now that option is gone so what is the equivelant.
