First post in the MasterCam section and I am needing help. I am using X5 and I am drilling a couple holes with a 1" drill then I am wanting to drop back into that hole with my .971 end mill and circle interpolate the hole out to 1.75. I cannot find a way to get my cutter to enter on the exact midpoint of the existing 1" hole. I know there has to be an easy way to do this, I just can't find the right operation or entry method. Please help!

circle mill toolpath will get you the results you need. copy your drilled ops down and change them to circle mill and select your tool and cutting parameters.

worked like a charm! I was trying to use circle mill with the circle geometry and not the center point. Thanks for the help!

create a point for the "drop-in point" , when selecting your chains, first select the point then the chain

- Mcam will descend on that point, & then use the lead-in/out settings to take up comp ( if used )

Method is good for 2D_Contours & the 2D_Pocketing operations
