Van de Graaff generator | IOPSpark

A Van de Graaff generator can produce extremely high potential differences (voltages). A small school version can pump a huge charge onto the top dome so that the potential difference between the dome and the earth can be 200 000 volts yet the total charge is so tiny that you only receive a small shock when you touch it. This makes possible dramatic …


Choosing a Sphere Machine – Lapidary Mart

The first thing to consider before choosing a sphere machine is, "What size spheres do I intend to make?" If you want to make spheres larger than 1" in size, then the Large Sphere Machine or 3-Headed Sphere Machine is your best choice. The 3-headed sphere machine is designed to cut from 3 sides and allows for slightly larger spheres to be cut than the standard 2-headed machine.

.5" Sphere Mill finishing help - Practical Machinist

.5" Sphere Mill finishing help I cut the grooves pictured below with a .5" 2 flute sphere mill. The machine is a vertical mill, 15hp. The speed was 40ipm at 6000rpm, .04" deep at .35" stepover. The groves are purely cosmetic but i would like to have a clean finish on them. Only one side of the tool causes the blemish on any one pass.

Mastercam > mill a Sphere surface

Hi, I'm trying to mill a cavity similar to an interior of a sphere and mastercam did not created G03 code for a complete circle.I use scallop with filter tolerance activated and when I post I have a lot of G01 not much G03 for one circle. In theory, I turn in round around my surface, I must have one G03 with I J for a complete circle and One G01 for linear positioning for the …


How to machine a hollow sphere - Practical Machinist

Thanks for the interesting ideas. I posted a sketch of the hollow sphere on the OP. Dimensions are not correct, but the idea is there. The two tubes on each end are to be welded on after machining is done. Machining will be done on manual lathe and/or mill. The interior surface can be rough machined.


How can I Mill a Half Sphere form.

Hello to All. Here is one for all you Code Masters. I would like to machine a half sphere form on my CNC Router ether by Parameter programming or by G Code, which has to run on Mach 3. After some deep thinking I wheeled out VCarve Pro to see if I could use this. Playing about with the spiral gadget and fluting I ended up with a cone shape which was radiuses over …

[hep-th/0501063] The Spectrum of Yang Mills on a Sphere

In this note, we determine the representation content of the free, large N, SU(N) Yang Mills theory on a sphere by decomposing its thermal partition function into characters of the irreducible representations of the conformal group SO(4,2). We also discuss the generalization of this procedure to finding the representation content of N=4 Super Yang Mills.
