Does anyone know of a downloadable "Ball cutting program" similar to the one that Marv Klots has on his web site. I have the 64 bit version of W 7 and it won't play nice with his.

The program I wrote recently should do what you need. It runs on Win 7-64 just fine.

Evan's program seems to have met your needs on this, so that's great.

As an aside (and I know it has been posted here many times before) it bears mention again for those who have not seen it before, there is another little program for this along with many other handy little programs for shop related stuff here:

Almost all of the stuff available there is created and offered to all for free by Mr. Marv Klotz. It is a great resource for us HSM types. Thanks Marv!

Marv's programs run in a 16 bit DOS window. 16 bit isn't supported on Win 7.

His programs run fine on dosbox on linux ( http://www.dosbox.com ) , I'd imagine they would run fine on the win32 version of dosbox which in turn should run on win 7 64.

They also run fine on Win 7 32 bit - no problem.

Best,

I went out and tried out the the co-oordinates as generated by Evans program and it worked slick. Maybe pictures tomorrow night if I have time.

Good to hear. This will be the first reported shop test of the program. :)

The first pic is the part just turned with the co-ordinates acording to the program. Not a full sphere, it doesn't make any difference to the program

The second is after about 10 min. of filing and polishing with various grades of emery paper etc. to remove the steps.

I also made a cardboard cut out of the profile and it was a near perfect match to the part, maybe not high precision by good enough for almost everything else.

You have to remember that on a lathe the X/Y axis are Z/X and use the right ones. If you reverse them it would come out funny looking. Might be worth a try just for the fun of it.

Looks good. I can add an option to the program to label the coordinates for lathe or mill. Would that be helpful?

It would probably prevent a few screw ups. One question Evan, why did you limit the interval steps to 1 deg, allowing a smaller step like a half deg. would give a finer incremental advance and a more accurate profile, which probably isn't really necessary so maybe I answered my own question.

Anyway, great program.

why did you limit the interval steps to 1 deg,

Lazy programmer. It makes formatting the left hand column easier. :)

As soon as I get my new machine up to speed with installing all the software it needs I will update the program with the lathe/mill option and repost it. If you (or anyone) can think of any other related options that would be handy then post them here.

If you reverse the coords you will find you are cutting a convex face.

Should have figured that one out myself. Brain old, not works so good

Nice job! Is the source code available? Is it in Visual basic/studio?
