You can, of course, get attachments for some tables to allow dividing. See HERE

Hi Ronan,
You can use a rotary table to cut gears or drill a number of equaly spaced holes without dividing plates. Just divide 360 (The number of degrees in a circle.) by the number of teeth (Or holes) you want. For example if you wanted a 33 tooth gear 360/33 = 10.90909 Deg Most rotary tables are marked in degrees, minutes and seconds so you neet to convert the decimal value to this format.
So 0.90909 degreed is 60 * 0.90909 minutes = 54.5454 Then 0.5454 minutes is 0.5454 * 60 seconds = 32.724 seconds. You could use a spreadsheet to do the calculation and list all the table positions.
In the example you would cit the first tooth with the table set to 0 deg 0 min, 0 sec. for the second tooth move the table to 10 deg, 54 min, 33 sec (32.742 rounded to nearest second) For the third tooth set the table to 21 deg, 49 min, 5 sec. And so on. You are more likely to make errors using this method than dividing plates. Here is some information on rotary tables that you may find useful.

Hi All

Below is a link to a spreadsheet I made up to calculate divisions using a rotary table in degrees or degrees minutes and seconds.

**LINK**

Just enter the number of degrees to divide…. 360 for gears but you can divide a smaller arc.
Also enter the nu,mber of divisions.
The sheet is smart enough to only show the settings needed, much easier to read. and smaller to print out and have by the machine to tick off.

That rather depends on the cam cutting method, you can do it without the calculations if its a short cam. With the R/T laid flat and the work held in a 3 jaw just wind the handle in approx increments, no fine setting of the cutter for every increment
