Re: [CAD_CAM_EDM_DRO] cnc/copy mill teach

Well Alan
You making it sound reasonably quick and easy....Indeed I want - eventually--full digitizing capabilities but want - right now- ultimate in speed for simple part outlines coordinates measurments..Why? ,,,Machining steel takes so damned long that always trying for quickest methods....Actually dont matter ..Getting ready at this moment to make 6 copies of an original Winchester Mod.65 lever action , tubular magazine , .218 BEE rifle...Not gonna hold off on that project long enough to set up a digitizer...But will spend much time measuring, drawing CAD, and editing G-codes...I know there is a more efficient use of time than the way I will do it...Maybe I just getting lazy.

Hi Steven,

Yes, it does take a lot of time to digitize to a fine grid. A course grid
would be faster, but it might miss some points.

The grid must be tailored to what you want to measure! An ideal way would
be to pick a set of points to look for and measure; that is, go to a
relative location on the periphery of a part, and take a measurement.
Probably how a feature a fancy CIM (? Computer aided measurement) system
would work. You'd have to know what you were measuring, and what "grid" was
needed where.

If the digitizing program is running under automatic control, then what's a
little time? Just experiment with grid size to get the detail in the
features.

A really smart program would take a coarse data set, and then allow you to
define detail in a series of little grids that matched the part to digitize.

Digitizing probes in CNC or (CIM?) programs can often be "jogged" to
features on the part to be digitized, and then coordinated recorded, faster
then reading and righting down coordinates (and less error prone).
