Re: [CAD_CAM_EDM_DRO] Dumb question on the drilling of holes

Dumb Answer for drilling holes.....
I couldn't help to think of a centerpunch I made for a 3 axis machine at a shop I worked at once. I took one of those spring/overcenter/snap type center punches and made a holder to hang it on a Z
axis.

In One pass one could mark all the hole locations with a center punch like that I guess.....

I however, used the setup for punching some artistic designs in thin Copper Sheet. I had a sheet of rubber underneath the copper and it worked pretty neat. I had used Signlab to create code, which
allowed if desired, a plunge to be dictated at every node. It was the first time in my life that I was looking for a way to "increase" nodes in a drawing !
