Tool settings in NX9 (Need Help)

Pioneer
Pioneer

Good day,

 

We have recently moved to NX9 from NX7.5 and we have this tool problem.

In NX7.5 when we are changing the tool holder and the (OS) Offset value but the tool data remains, and if we create a new operation with the same modified tool it will just retrieve the tool data from the library like the speed and pitch or depth of cut value. But now in NX9 we don`t know if we are just missing some default setting to automatically retrieve tool data from library even when we change the (OS) Offset or holder, so that we don`t have to input again the tool data in each operation with the same tool.

 

Thank you,

Jayson Cabana

Hi,

I don´t know if I understand you correctly.

Check if in the Customer Defaults you have enabled:
Manufacturing -> Operation -> General -> Machining Data: enable the check box called "Automatically Set in Operation"

I am not sure exactly what the issue is.

 

If you change the Tool Insertion Offset of the tool, and then Set Machining Data, the parameters are recalculated based on the new tool length sticking out of the holder.

 

If this is about always updating the operations, then as Joachim said, be sure the customer default is set.

Good day,

 

Yes I have checked the set automatically in operation, but if I change just the tool holder it prompt a warning  (You have modified a tool which was retrieved from an external library. Do you want to keep your modification?) so I will select yes option, and when I create another new operation with the same tool that I have changed the holder i will prompt a warning (No entry was found in the Machining Data Library that matches the current Part Material, Tool Material, and Cut Method.). In NX7.5 even if I change the tool hoder, this warning don`t popup, as long as I don`t do anything inside the tool tab parameters. 

 

Thank you,

Re: Tool settings in NX9 (Need Help)

Are you calculating the machining data based on part material, tool material, and cut method?

Or are you using the tool machining data tied to the library tool libref?

 

Changing the offset should mark the tool as having been modified, but it will still know it's original libref.

Markrief,

 

I am using the tool machining data tied to the library tool libref. I  have attached some image please take a look at it.

Re: Tool settings in NX9 (Need Help)

This looks correct to me - once you change the tool, it is no longer a library tool.

Let me explain...

 

A library tool is an assembly, including the holder. If you edit it, it is no longer a library tool. Changing the offset has the same effect as changing the diameter - the system knows that the tool in your work part is not the same dimensions as the one in the library.

 

Tool machining data is for library tools only. When you set machining data, since the tool is no longer a library tool, the system does not look at the tool machining data table, I goes directly to calculating the feeds and speeds, and does not find the necesary inputs.

 

You did not see this in the old release because the tool was not getting flagged as editied when the offset changed - a problem that we fixed.

 

If you want to keep and reuse the tool with the new offset, I suggest you export it to the library, either replacing the previous tool, or creating a new one. If you create a new one, add tool machining data for the new libref.

Mark Rief,

I am sorry I dont get this, does this mean I have to register the tool in the library every time I change the insertion offset value or the holder type for re-use? We usually change holder type to prevent collision onto the part, but we don't change the feed and speed of the tool so when we create another operation we just have to select the modified tool and generate it don't need to re-type the feed and speed and the cut value. Is there any possible solution beside replacing or uploading new tool data in the tool library? because we are using one shared tool library so we don't want to replace one tool data, we also don't want to add new tool data with different holder but the same tool diameter and tool length..

Thank you,

A tool from the library is not editable, this is the purpose of a library tool.

Library tools are meant to be always the same and to not change at all.

 

If you like to change the tool at will and keep the machining data for the diameter and the tool length, then you need to switch from "tool machining data", which is bound to a fixed library reference, to "machining data", which is bound to diameter and length of the tool.

 

In general it is total nonsense to change a tool retrieved from a library, since that is representing a tool that you can get from the tool preparation department by just showing them the tool ID (library reference).

Usually changing library tools is even locked, so you can't do that at all.

Thank you for all the replies.

We will try to move to machining data to see which one is better in our situation. We just can't avoid to compare the NX7.5 to NX9 because we just moved recently. Thank you again to your help..
