drill bore cycle in featurecam

our shop regularly uses carbide inserted drills to do some rough boring of holes before finishing bore operations after drilling. I was wondering if there was a way to perform an operation such as this in featurecam. any help would be greatly appreciated.

Hi @Anonymous,

 

Thanks for raising your query through Autodesk Forum!

 

Are you saying drill/mill in FeatureCAM? If yes, then it is already available. While creating hole feature, it asks for machining type in new feature strategies 'Drill only or Drill/Mill. Select drill/mill and check for the options.

 

Select the strategies that you want to enable. The options are:


•Drill full diameter
•Rough with Drill, Finish with Bore
•Rough with Drill, Finish with Ream
•Rough with Endmill, Finish with Bore
•Rough with Endmill, Finish with Ream
•Rough with Endmill, Finish with Endmill ◦Finish Bottom

•Rough with Endmill to full diameter — this option lets FeatureCAM rough to the final hole diameter without having a finish pass. ◦Use hole milling canned cycle if available ( ) — For machines that support hole/bore milling, such as Heidenhain Cycle 208, Siemens POCKET4, Fagor G88, and Haas G12/13. The hole milling canned cycle is posted using the hole milling format in XBUILD. If you enter a G code, for example G208, for the Hole Milling cycle in the NC Codes dialog in XBUILD, that code displays in the brackets after this attribute name, for example Use hole milling canned cycle if available (G208).

 

Hope this helps.

no, I should have been more clear in my initial post.

 

we use this operation on a two axis lathe, we drill the hole with an inserted drill then proceed to use the drill as a de facto boring bar to get us out to a rough dimension. I have been hand writing this portion of the program but was curious as to whether featurecam had a feature I could use for this operation or if it would require some sort of work around. hand writing it is not the end of the world, however I was just curious if this was something built into the program or not.

Yes, we do that also. We setup two tools with the same tool number.

 

Tool 1 drill

Tool 1 boring bar

thanks jeff i'll give that a go with my next program. how do you define your boring bar just out of curiosity. or do you just have it set to start the bore at x0???

Not sure I understand the question but I think you want to know how to adjust where the bore feature starts cutting. The bore feature requires a curve to define the finish bore profile, the bore operation has Boundary (min radius) and Boundary (max radius) settings and they determine where the bar starts cutting.

For a two axis lathe, id do the following - design two tools.

 

Say you are using a 25mm u drill

 

Program a drill cycle with the u drill (standard).

- call tool IE T0101 - set as X0 in the control geometry page etc 

- Drill to depth.

- retract.

- rapid turret home / safe index point.

 

Program a rough bore cycle starting from u drill dia.

- Design a new bore tool that reflects your u drill parameters. IE - min bore 25

- I would use a name like -  24MM 8XD U DRILL - AS BORE.

- bore curve is a line at 50mm

- use a stock bore curve is a line at 25mm dia.

- On machine use tool same tool station, different geometry / offset number IE T0121

- set /probe your u drill as a boring bar - IE probe the outside tip as you would a boring tool.

 

 

Obviously you'll have the turret retract out of the hole after drilling and go 'home' before the boring op takes place, but you could mod that on control.

 

I tend to do it that way (may not be the best way!) because it gives me decent control over both operations. 

 

 

The .png .fm file should explain more
