What's the best way to program this part ?

[Dreas]

Hello,

 

i have to engrave this on a lathe.

I've tried C-Axis Contour with chain one segment and than toolpath transform-rotate.

But i always get a message warning.

I've tried also other settings in the T/C-Planes with no luck.

I have set my machine definition with the lathe mplmaster post.

When i try to set my T/C-Plane to other than top i also get a error message on posting.

The only way to program the part is to chain all the lines in 3d.

So, what's the best way to engrave this part without lots of retracts and machine the contour double times, because i have to take multiple steps ?

I made some baseball bats and engraved the kids names and team name as trophies a couple of years ago.

 

If memory serves, I used the mill contour tool path and rolled it around the cylinder. I then manually changed the A axis to C axis and the other changes necessary to machine this part on my lathe.

 

I had to do it this way because I didn't have lathe at the time.

Engraving a text or just a contour on a cylinder is not my problem.

I want the contour rotate with the transform toolpath over the cylinder.

[Jayson Kramer]

you would not you transform but this is a axis Sub type of path.

 

I would take the profile and unroll it and then due a contour, from here use the option of Axis rotation and this will wrap it around the dia you define and out put this for the forth.

 

Example of some old work done this way.

Just want to show you how i've done the part.

I unrolled the contour and than chain, as best i can, without having double lines the first two segments.

Then take a C-Axis Contour toolpath and do a transform with copy several times.

Looks good for now.

 

Thanks,

Chester thanks for sharing that is what the forum is all about.
