Re: Caudlet's Overview

Thank you, Tom, for your posting; # 53116.
As one of the newer members, faced with the daunting task of gleaning
info by combing through many past posts, I welcomed your synopsis.

My project will, theroretically, supply 200 inch.oz torque at 400 rpm
(330 lb-f at 100 ins/min with +/- 0.00125 inch on 4 TPI ballscrews).
Now, if someone would review the typical machining speeds, forces,
(for various materials), of our design envelope, I would know where
it fits, and it's limitations and required improvements.

As feedback for this Group, may I venture to suggest that many
Newbies like myself have actually done some extensive technical
homework, but are unsure of some terminology, product brands, and
conventions. Many of us would welcome more overviews such as your
posting and would sooner contribute to the knowlege base here, if
only it didn't take so long to find out what a "knee" was, and
that "23" is 2.3 inches, etc.
While on the subject of contributions; I have made a spreadsheet
analysing torque / force / power / shaftspeed / feedrate / resolution
interdependence, for my project, but have no idea whether it would be
welcomed as generally useful (and what is that "no attachments"
bit ?).
Perhaps one of the Old Hands will look at it first, if interested.

Thanks again. I'm having great nerdy fun here. :) Don.
