force tool change

[CJF]

Using mill level 3 of version 9, I want to force a toolchange between toolpaths using the same tool. If I use the force tool change in the change nci page, it puts a tool change at every retract. Is there a way to have the toolchange only at the start of the toolpath?

 

Thanks,

Jack

If I remember correctly (probly don't) there's a force toolchange under the planes button. It works at the beginning of the operation.

[CJF]

Looking in the planes page, I don't see a force tool change.

[Guest]

Isn't there a "Force Tool Change" on the tool path parameters tab?

 

 

Or is that the one you're checking?

 

In my "advanced" years V9 has become a rather fuzzy memory

 

[Colin Gilchrist]

In V9, Force tool change should only put the retract and tool change header at the start of the operation. What Post are you using? You might try downloading a copy of the MPMaster V9 post and posting with that. That would be a good test to tell you if it is the post or not.

 

For example, you should be able to write a contour operation with three separate chains, and the toolpath should cut all three, retracting between cuts, but only put the toolchange at the start of the operation.

 

HTH,

create new tool, but the same dia and number.

when posting answer yes for tool change.

change the # every time the software sees a different # it will force a tool change

I have been wondering about this feature. Can someone give me some examples of why you would want to force a tool change. Forgive my ignorance on this subject.

My toolpath is engraving, in .010 steps. The toolchange comes with each move to a deeper z.

In explanation, I'm engraving similar parts with

increasing #s B-1, B-2 etc. and just want to make one toolpath with all the different numbers in it-the operator will just go to the toolchange at the appropriate number. I know there are other ways of accomplishing this-same tool different # etc. , but once I tried this I'm curious how to do it. Especially since the guy using Unigraphics can do it.

 

Thanks,

To move/remove clamps, to remove chips/chunks of material, to make sure the tool isn't broken...

[Justin Beebe at Folsom Tool]

Those are good examples. This now leads me to ask if the machine will stop at a forced tool change if the optional stop is not turned on. For example does it post an M01 or an M00 at the tool change. If it does post an M00 then it seems very simailar to a regular M00 or am I still missing something. I am in no way critcizing this technique I just want to understand it more. I guess my question is couldn't all this be accomplished with an M00.

 

Justin

[Ocean Lacky™]

Typically, it will post an M01.

[CJF]

The mpmaster post does the same thing- puts a tool change at each z depth change. Is there a way to force the toolchange only at the beginning of a toolpath with multiple depth cuts?

 

thanks,

Took a while to remember...........

 

 

I think this is what you are looking for.

 

 

 

click on change NCI button

 

Click on force tool change

 

 

Do this on each operation you want a tool change at.

HTH,

 

That is the button I've been using. It puts toolchanges at each retract in a multiple depth cut toolpath.

 

Thanks,

 

Jack

You must have something else turned on, this should only give you a M01 @ the beginning of the operation, not for multiple depths inside of an operation.

 

 

[Midwest]

HTH means Hope This Helps

 

 

[CJF]

Sorry about the hth.

 

If I have something else on, I'll keep looking.

 

Thanks,

CnCjb I use the force tool change options for a couple of different reasons.

 

 

Reason 1. When posting for a haas lathe if I use the same tool to ruff and finish. I use it on this example so it post the finish tool path separate so the operator can run the finish only instead of the entire ruff and finish.

 

Reason 2. when I have to spring parts in a vise or move clamps I send the table to the part change position ( Via manual code), if you don’t use force tool change the machine assumes the part is still where it left off. With force tool change the tool reinitializes. (Tool offset spindle speed part location ect.)

[CJF]

Midwest,

sorry to keep bothering, but could you confirm that a simple contour path repeated with muliple z steps will not give a tool change at each z change when force tool change is on with your post processor?

 

Thanks,

Thanks for the info.

Thanks Midwest, I don't know what I'm doing wrong but at least I'm assured it can be done.

[Midwest]

what post are you using?????

 

Maybe put your file on the FTP.
