How need to engrave on a angle?

[millman2002]

I need to engrave on a tapered tube. I am useing Mastercam 7 (Level 1) on a Fadal with rotery axes (A). I can do a cam wrap G17 to translate Y movement in to rotary movent. But the tube is tapered 1 deg. and the Z depth will constantly be changing. Can I rotate the geometry in Mastercam 1 deg around the y axes and get mastercam to out put the X Y and changing depts in Z?

Thanks

Gary

5axis cure out put as 4th.I can't remember if roll die will do it for it might.

The way I have done this with 3 axis is by projecting the toolpath it works well for me.But I know alot of others dont like doing it that way.Just an idea.

Mold100, I like that one too ,but it is not real 4th.

If there is room that is a great path.

I keep forgetting to make that one if it is permitted.

You can always project the lettering (or toolpath) onto a tilted plane defined by a surface, then apply rotary substitution in the toolpath.

Hey dave i like that.

I could see that working.

Jay,

 

You may also re-read the initial post from millman2002.

I don't believe level 1 has 5 axis toolpath capabilites, even if just to output 4th axis or axis substitutions. I could be mistaken but think that Dave's solution is much more viable for millman2002. Especially in V7. Just thinking about trying that toolpath without surface or associativity in rotary work makes me cringe.

 

millman2002,

About the only way I can think of is to project the geometry onto a surface and perform a 3D contour on the geometry. You can create the surface and then Create-Curve-Project the 2D geometry onto the surface. Then contour the geometry that was projected, selecting it with a window. You will also want to change all of your depths to Incremental, or a specified distance from the geometry location. This will not ouput incremental code if your post is not setup that way. You may want to place the projected geometry on a different level (layer) and color to make it easier to select when the time to toolpath it comes. HTH

Good point Peter, no i did not catch that.
