I have an Acu-Rite Micro Line DRO on my mill. I am trying to use the

bolt hole function but am having some problems. I zero the workpiece

which is a chuck backplate and then enter the appropriate numbers into

the the DRO.

It is not working. The first bolt hole is 60.6218mm from the center of

the backplate on the X axis and 35.000mm on the Y axis the bolt hole is

30 degrees off of the X axis in a counter clockwise rotation. The

radius of the bolt circle is 70mm. There are 6 bolt holes on this

circle which means that there are 60 degress between each bolt hole.

How should I program this into the DRO? The first question it asks is

the number of holes, which is 6. It then asks for the center of the

first bolt hole in X and Y coordinates which is X = 60.6218mm and Y =

35.000mm. It then asks for the radius which is 70mm. It then asks for

the start angle which is 30 degrees.

Should I use the DRO to drill the first hole at the above X and Y

coordinates and then program the DRO? Would I still use 6 bolt holes

and just use the starting hole as the one I just drilled? From the

instructions that is what I am gathering but I just want to make sure.

Any help greatly appreciated.

Thanks, Steve
