Questions: M3Turn Tool Table
« on: December 28, 2007, 04:04:24 PM »
Hello All,
What is to be entered in the "Tip Dir." column in the format illustrated ? 
Chapter 9.2 on page 94.
Is this taken care of by using G41/42 and to be disregarded ?
Is all that is needed the X and Z offsets and the tool tip radius ?

PS:  Tried to post the screenshot, print screen, paint, paste,additional options, browse. All went well...but the file was almost 3 meg. How do you make them smaller to post more quickly ?

Thanks,
RC

I just use the X and Z offsets, wondered about the Tip Direction a while back and Graham answered my question, you will see it here http://www.machsupport.com/forum/index.php/topic,4413.0.html
 Not done much with the lathe yet as I still dont have it totally finished but so far I have not found the need for tip radius entries.

Oh and for screen grabs get yourself the free version of ScreenHunter, you can capture and save images to a location you choose, you can decide how to capture the area you want etc etc and typically it will save a full screen well under 100KB.

Hood, Thanks twice.
Graham's explanation was excellent as always. I saw a similar illustration in the Turn man. but did not understand totally.
To shed a little light on what I'm into:
     I need to cut a .005" radius from the face of the material to the OD, or vise versa, with a tool tip radius of .005".
The only way I can get it close is with a super sharp point, which is no good of course. The comp. should do exactly what I need if I understand it correctly and can get a grip on it.
Everything I've tried so far goes totally NUTS.

1 more question: The manual said something to the effect of : This is under development in Mach .
I hope it is working properly and I'm not beating a dead horse. Do you know if it has been finalized ?

Give me some dimensions of the arc and part you want to cut and I will give you some sample code.

Do you work rad or dia?

Hello Graham,
I'll try to send a sketch.
Dia. mode.
It's actually tubing and I am facing from the id outward, then the radius, then the taper.
Thanks,
RC

This is a sample of the code you will need to produce the part.


(USE TOOL OFFSET TABLE)
(SET TIP RAD TO MATCH TOOL)
(SET TIP DIRECTION TO 3)

Thanks Graham, I'm anxious to run it tomorrow.
I was using the Center Format, Inc. IJ previously. The Radius Format method looks simpler. I had not tried it.

Getting better every day, with help of course.
Thanks to you and Hood for the Screen hunter tip, it's really KEEEEN.

I'll soon be needing some sort of auto feed system, that's another topic.
Thanks again,
RC
