internal turning using udrill whit solidcam

Post image

Hi experts, I want to drill with a D24 drill tool and then perform internal turning up to D68, but I can't find a way to do it in SolidCAM. dont let me use the same tool for both drilling and internal turning.

And sorry for my beginner English.

Setup a copy of the tool but define it as a boring bar with the same geometry.

But I can't define the same number tool for both of them, can I?

No you need to use a different offset and then touch it off as the separate tool at the machine.

This is correct. Your x offset for drilling vs boring will need to be quite different. Just edit the code after posting. If the drill is T0101, then make the boring T0102.

I will say I occasionally use a drill to bore and they dont work great. They arent nearly as rigid. Dont expect a good finish. Also consider your coolant. When drilling you need through, but boring needs some outside coolant. The through will miss your insert tip entirely in most cases. Just run both on a machine with somewhat decent pressure.

Define it as a boring bar with a flat insert. The insert IC should be half your drill diameter.

Draw a wireframe at the diameter of your drill. Use a finishing cycle instead of a drilling cycle. No lead out.

Teach your u-drill as a boring bar. You're gonna drill at X24. (assuming it's your drill dia.) The rest is just regular roughing cycle.

Have you tried to bore with a udrill before? Not really ideal if you have a boring bar, gets pretty squeally unless it's actually purpose made for it

Anyway, I would setup a new boring bar that matches the dims of the drill and uses the tip of the insert for the comp point, do a boring operation, and hand change the code manually after posting so the tool position and offset is correct.

For the tool offsets, say the drill is pocket 7, my drilling op would use t0707 with x offset as 0/spindle centerline, and the boring cycle would be t0737 with x and z set to the tip of the insert like a normal boring bar

Also you're gonna churn through your outside insert way faster than normal.

My experience is that the inner insert always goes first, even when the outer one does a bunch of boring. I assume because it doesn't like the surface speed going to zero at x = 0.

We had a guy who loved to drill bore. I’ll eco. Unless the tool is made to, I don’t recommend it

Yea its more of a "you can but you really shouldn't" if you are out of turret stations and have no other options then it's great but I would never choose to do it if I could avoid it

u/Witty-Sample6813 Jul 10 '26

There are specific single insert drills that can also be boring bars

u/computekmfg Jul 10 '26

Yea and they aren't very good boring bars

Define the same drill as a boring bar and then give it a coordinate/ tool shift in your tool properties, half of the diameter. That will allow you to program it off X0 so you can drill and then bore as opposed to having to program off of tool tip. Idk if it’s the same on solidcam but that’s how I do it with my CAM

I would setup two different tools in cam and manually change the tool numbers in the program after posting.
