Tapered mill in Mastercam Lathe

[Roger]

Anyone know how to use, or create, a tapered endmill with a flat in LATHE?  Please share if you can.  I created a tool in mill, and exported.  The NC code is not correct.

I've done this in mill, I don't see a way to do it in lathe.

Hi Roger,

I think i would just lie to a center drill as shown below or use the custom tool suggestion.

Thanks Josh,  Modifying a center drill works for this.  But when I choose  the depth calculator, and put in the diameter I want, it doesn't work right.  I know I could do the math, but......there should be an easier way.  Like choosing a tapered end mill!  I've used custom turning tools, but I can't seam to find where you can do a custom drill tool.

Please note I am still X9

There are 2 Tool Managers in Lathes with live tooling (under the Toolpaths tab at the bottom in X9), one for lathe tools and one for rotating tools. You can drop it in there from a tool library, never tried it with a custom tool but I do it with standard tools all the time.

That's what I'm saying...........Josh's modifying a center drill will work, with the above mentioned problem.

yea i assume he was talking about a Live chuck and dead drill. Not a live drill. If its a live drill or mill, then you are correct that it is very easy through the Mill Tool manager, if its a rotating chuck and non rotating tool its gonna need to be defined as a lathe tool.

oh i see roger, yea depth calculation wont work correctly with the way we lied to that centerdrill. That was just a work around since i dont know of a better way to get this done, in my opinion there needs to be some additions to the Drill selection for Lathe drills. might be a good thing to send up as an enhancement request.

[Roger]

Sounds like an enhancement request to me also!!!

I guess I am a bit confused as to why you would want to run a fixed tapered fluted tool rather than just a boring bar to generate the taper...?

Bore is .125" diameter.

try to cut an angle in a .093 hole with a boring bar

Got it....!! So you really are using it as a fixed drill, I'm sure there must be a way to do this.......

Does the depth calculator work if you define a rotating tool? If so you could use a custom tool definition in Mill and do a Custom Drill Cycle with a dead spindle....? Might not even need an actual Custom Drill Cycle as the spindle activation is handled in ptlchg_com. But you could drive it with a Custom Drill Cycle call and have it listed in the drop down as Chamfer/Countersink....I (and others) use this for a Locator Drop Pin in Mill. Or maybe through the Lathe misc drill cycle, but I have no experience here.

Maybe I'm missing something here, but couldn't you use a Reamer definition, and just adjust the "angle" of the chamfer to give you  what you are looking for?

Colin,

Maybe you know something I don't.  Where can you adjust the "angle'?
