RE: [CAD_CAM_EDM_DRO] Drilling with Vector

What controller software are you using? If your software supports a G83 then
you are in business. Just select all the points (you do have them at the
depth you want to drill?) and then generate the G-code. Vector will give you
a G81 canned cycle. Now go and change the G81 to G83 (peck drill cycle) on
the first line and remove G81 from all the other lines so they only have the
X & Y coordinates. Now add the following parameters to the first line with
the G83 (values are representative, use what is proper for your machine)
R.25 This will set the amount the drill retracts above Z0 which should be
the top of your work
Q.125 this is the advance per peck
F5 This is the feed rate
So your line will now look like this:
N10 G83 X0.000 Y0.000 Z-0.625 R.25 Q.125 F5
Now when you give the controller an XY coordinate pair it will repeat the
peck using the parameters you gave it when you set it into G83 mode only
altering the location. To cancel and get back to normal mode put a G80 at
the end of your peck drilling.
