General Mach Discussion / Re: Problems threading on the lathe
« on: September 29, 2009, 02:14:34 PM »
Thanks Art,
Depth is not even a concern for me, it's the lead / longer threading, as shown by what i just posted.
The x axis is very accurate in it's moves and the Z is almost neglagible.
I am going to guess that i can cut threads out to about 3/4" to 1" all day long and they will be good.
Hope i don't seem anal about the threading. For what i do this lathe will be fantastic.
So over time i will try a different PC and have a friend look at the sensor triggering / timing since he has
the equipment to do it and is extremely knowledgable.
What fooled me was the distinct cuts, and you got to watch each and ever one of them to get the story as i just
posted.
By the way, a good test of the sensor triggering would be to do multiple start threads.
Another would be to pick the thread up and recut it ( it's somewhat of a bitch to do in CNC). I posted something in members docs on how pick the thread up.
I guess the thought here is to eliminate the problem such that no correction will be required. Maybe wishfull thinking with the computer and sensor currently in use, but, wouldn't know unless some testing was done.
As always appreciate the comments,
RICH
