The other day I worked on a simple engraving project for a client. From that experience I wanted to share some how to's for shops just getting started with CAD CAM for engraving.
Stock:
I used an oval wood plaque from Joann's. This was cheap to buy and already had a beveled edge. Really you could use any stock, this is just what I used. The plaque cost me about $3
Tool:
I used a Amana Tool Carbide Tipped Router Bit. #45716: V Groove 3/4 Dial 1/2 Shank. The tool cost about $25

What I show you how to do is draw you stock, create text, bend text to a curve.
The real trick to setting your zero, is having the part drawn on X0 Y0, creating a sketch with a cross hair on zero and printing out the drawing at a scale of 1 to 1.
You will tape the drawing to the stock and use the cross hair to line the work offset up at the machine. This is a very simple trick for setting the part zero and making sure the engraving will fit on the part and cut where you want to.
CAM, creating tool path.
In this video I talk about creating tools and saving them in the tool library. Loading tool path features that you have previously setup with working settings.
