Single point threadmilling in a Fadal?

[John T.]

Can a fadal handle single point threadmilling?

 

Or should I use one of our harder-to-get-time-on Fanuc control machines?

 

 

The tool I have is a "accupro" brand, 5/16" shank, .230 diameter at the cutting head, I need to cut about 1/2"-3/4" deep. The thread is a 1 3/16 x 16tpi. Can anyone suggest speeds and feeds for this?

[htm01]

if it can't use it for a boat anchor!

 

should be able to.

[Guest SAIPEM]

Yes it can.

 

The code below will run on both.

Speed & Feeds will depend on the material you are cutting.

What is the Material you are cutting will change according to that? Fadal can handle this with no problem.

 

Steel probably 750 rpms 5 ipm

 

Alum probably 1500 rpms 5 ipm

 

Brass probably 1250 rpms 5 ipm

 

SS/alloy steel probably 500 rpms 2.5 ipm

Or to shorten Saipem's example.......Only on fadal

Eh, forgot the material! It'll be 6061 alum.

 

But those samples should get me going, Thanks!

Well I drew up a tool that is 1" wide from the X0 per the MCX2 help file, saved it as a MCX file. I created a library, but when I try to import the tool, it keeps asking me for a tool library also, and in the end there is no tool in the library. What am I missing??

[Guest]

Now, create the tool path and then in the tool window, right click and "Create New Tool", you can click on file on the lower section of the tools definition tab and navigate to your custom tool, set everything you want and the save to library.

 

The tool will now reside in your library accessible for use at any other time as well.

 

I would suggest using the "Undefined" type for this type of tool, don't forget to set the tool diamter properly as well

140sfm /.0015 per tooth in mild steel. 300sfm / .003 for aluminium. This worked on a single point tool, (6 teeth on the same plane though, carbide tool from Micro 100), going 2.65 dp. Had to offset the dia. in mild steel quite a bit .
