Lathe V9 Threading

[jmm0422]

In version 9 how do you change a threading tool to be at Z0 at the face of the insert instead of the tip of the insert.

 

We touch our threading tool off at the face of the tool not the tip.

jimm, We also teach our threading tools on the face of the treading insert. As long as you have the tool setup correctly in the library it will account for the tip not being at the face Z0

That is what I am trying to figure out. How do I set my tool up correctly in MasterCam?

jmm,

if you select the tool and then go to draw tool if the face of your tool is at the "z" orgin line you should be all set, hth

[jmm0422]

It is not at the face it is at the tip of the threading insert. How do I get it to the tip?

Here is a link to the picture in the FTP site of what I am talking about. Threader

 

Maybe this will help clairify what I am trying to do.

 

I need to move Z0 of my tool from the intersect of the threader to the facce of the threader.

he way I do it

 

I created a custom tool with the face of the insert at Z0

 

Suggustion on drawing the tool:

 

- Select the holder with a thread insert that has (roughly) the same dims as the tool you will be using. Click on 'Draw Tool' and select 'File Save' from the screen menu.

 

- Traslate the holder and insert so the insert face is at Z0 and the tip of the insert is at X0 (mod. the tip radius if needed) and use the result as the .MC9 file that your custom tool is based on.

 

Lathe custom tool geometry rules:

There must be separate planar closed boundaries for the insert and holder drawn in the Top view.

 

The boundaries must consist of lines and arcs only.

 

The insert and holder geometry must be different colors.

 

There must be no other geometry in the file.

 

Endpoints of entities defining the outer boundary of the insert and holder must be within .00000005, or you may get error messages

 

It work for me

We also get the "Z" offset from the face of the insert

 

Hope this help

This is my custom insert

(I belive this is what you're looking for)

Jason,

 

CR has told you the way to go for what you are asking. Give it a shot.

Man I feel like an idiot. I still can not get it.

 

CR what you have is what I am trying to achieve.

 

I went into my custom tool and hit the draw tool, file save. Then opened up that MC9 file and transformed between points and moved the face of the insert to Z0. and then file, save.

 

Went to do a threading tool path selected my custom tool and when I went into the parameters and hit draw tool it still shows it with the tip of the insert at Z0.

 

What did I do wrong?

Jason

 

I upload a file with a thread cycle in th ftp site

Lathe/threading.mc9

 

It has a thread custom tool.

 

Saved it in your tools directory

[jmm0422]

OK. I see what I was doing wrong. I had modified the shank of one of my standard tools and saved it. I was then trying to transform the standard tool from the tip at Z0 to the face of the tool to Z0.

 

I saved my standard tool in my library then pulled that geometry into a custom tool. I was then able to select the GEOMETRIC TOOL ORIENTATION IN TOP VIEW, and TOOL ORIENTATION IN TURRET to the face of the insert and the tip of the insert at X0 and Z0.

 

Thank you guys for the help. I really appreciate it.

 

Jason.
