Calculating distance travelled per revolution

[I_am_a_genius]

Hi,

A cylinder is to be coated on a rotating lathe, with a coating rod moving by a mechanical robot in the X direction (back and forth). The cylinder is 300mm in length, 19mm in diameter.

What is the distance traversed per revolution of a rotating cylinder, with the lathe rotating at 1200RPM, and the coating applicator moving at 0.05m/s?

I am wanting to avoid the barber pole (spiral type effect) when coating the cylinder, so I need to select the optimal RPM, and traverse speed.

Cheers
