Fanucs have a mirror function about the x and/or y axis. I suspect most VMC controllers have this.

Statically, you are not even close. If you use a coefficient of friction of .1 then the max axial force it would hold would be 4 x 4067 x .1 = 1627 N.

Not to take traffic away from here but there might be more grinding specialists here: https://www.practicalmachinist.com/vb/abrasive-machining/ I'm sure they'll want a picture showing the problem.

Bharath - I thought the following might help: https://mae.ufl.edu/designlab/Lab%20Assignments/EML2322L-Tolerances.pdf

Machine accuracy, machine repeatability, operation (drilling, reaming, turning, grinding, honing, interpolation, boring), tool wear come to mind.

It's a function of the machine, not the g-code generated. If you tell the machine to go to 3.5 on the X axis and 2.1 on the Y axis the machine will go to exactly 3.5000, 2.1000 within the limits of the precision and accuracy of the machine. If your machine is off .005 then the 3.5000 could be...

At this point I'd move it to the Gear & Pulley forum under mechanical.

Probably o.k. here if it's more of a manufacturing issue. There is a Gear and Pulley engineering sub-forum in the Mechanical Engineers forum. I'd use that if the question is more about engineering the gear.

Interesting application - for what it is worth, my 20"x40" VMC has no trouble breaking 1/2" end mills with the x or y axis. It does a lot of damage also when the vertical spindle crashes into the part.

As long as the threads are preloaded sufficiently by your nut, I wouldn't worry about the threads. Make sure the shank of the bearing can handle the bending and shear loads.

This popped up in another forum - a list of books for tool and die designers: https://www.practicalmachinist.com/tips-and-tricks/5-books-for-tool-die-makers/

I'd guess your tool cutter would want a 3d solid model. Solidworks is nice but expensive. If just a drawing and 2d is o.k. (contact your tool manufacturer) then AutoCad is good but also expensive.

Machinery's handbook for starters. Lot's of info on cutting tools. Maybe a general machining book - like Machine Tools and Practices by Kibbe, Neely, Meyer and White. Any end mill or drill manufacturer or carbide insert maker will have useful info on their websites - try Kennametal, Emuge...

There are a bunch of machinists that hang out at: www.practicalmachinist.com The "General" forum would be your best bet. It's tough to get the nub off the middle since turning the part produces a velocity of zero on the centerline. I'm guessing if you want a nice clean spherical radius with...

Are the holes to the right large enough that you could get long drill bits through?

Do you have live tooling on your turret? From what I see most of the mountings are DIY. There's probably a general reluctance to grind on a machine not meant for grinding - problems with grit getting under way covers and into coolant.

If the part is injection molded plastic you can use "side pulls". I think they maybe are also used on die cast metal parts. Lot's of money though!

"Radius" is often used in a 2-d sense to specify the radius at the intersection of 2 surfaces. As mentioned, "spherical" generally refers to a 3 dimensional feature.

On something like a saw blade, wouldn't there also be bending loads in addition to the tension loads? Maybe they're insignificant.
