Re: Intro and Beginners

Hi Tony, Let's start with a milling machining center. Once the part
is mounted to the machine you'll need to pick up the edges it is
dimensioned from. You can use an edge finder or if dimensioned from
an existing hole an indicator. At that point you will establish a
zero point. Then if using G codes that will be your G92 program
start point. That line of progran will read G92 X dim. Y dim. Z
dim. This is a non move command and tells the machine where to start
from. The following commands in the program tell the control the
direction, distance, feeds, speeds, and aux. functions (i.e. cutter
compensation right/left, coolant on/off etc.)The commands are
different for a lathe but similar in principle. This is the short
story Tony as there is not enough room here to tell it all but just
to give you an idea of how to get started. If you want to know more
and have specific questions email me out of group and I will try to
help. Good luck with you shop.
Regards,
Tom
