Good morning,
I am going to be working on this part sometime real soon. What is this best way to set up the hole operation. I have attached a cad picture. The holes are inside of the hole. One has a counterbore
.
For setting up those hole operations, use the actual holes as reference surfaces. So that your XYZ are the way you need them to be. A bit hard to judge from this angle, but is there enough room to make these holes?
I am not sure if I have the room. I am guessing, that I would have to use a long length drill and endmill. This looks daunting!! I am glad I have some time to figure this out. I was given the CAD without a print. Was told that CAD was master.
Difficult to visualize, the angle of the two holes at the bottom of the center hole may be too severe to drill from the view as shown. You may have to drill the holes from the back side. Although adding a counter-bore on this side would indicate you might be able to drill from this side… Depends on the depth of the big hole, if it is shallow you may be able to drill okay.
Man, it could be me - but just looking at that picture alone, those holes look to be at angle compared to the main bore, and the way the start of the inner hole edges look - maybe , just maybe, the bottom of the main bore looks like it cpild be an inverse radius/dome shape. This part maybe a little tricky and may have some more setup and backside machining to consider as the post above me mentions.
Can you toss this into a quick print and do a cross secrion view to get a good idea of what you are dealing with? You dont need callout or measurements, just a view into this. Maybe put a picture back in this post - there are so many good experienced people here you are bound to get some good ideas to work with.
Good morning,
I can draw a quick print or, I can send you the STEP model to look at. You was correct in that the main hole has a curvature and smaller holes are at an angle. I will send to you as soon as I open the computer.
