would like to know...

Hello list, we now have 110 listees.

I would like to place a question for the list that has been bugging me.
In most of what I have read, a tool is changed automatically in the
professional machining centers, CAM.
How are tool changes handled in the smaller equipment like the Sherline, and
the modified manual machines?
I realize that it has to be done by hand, but how is the programing handled,
so that machine can be powered down, and restarted when tool is changed.
Also in the programs I have looked at, commercial, the characteristic's of
the tool are placed into the program.
How is this done in the small programs for the Sherline's , etc.? Also how
is the tool position and the program synchronized at the start of machining?
And after a tool change?
