If you have tried reading a book or manual, you may have some specific question.

G73 is used to rough a uniform contour of a known thickness.
G73 U___ W___ (U is amount of stock in X, W is amount of stock in Z) R is how many passes you are going to remove this with, assuming 8 mm for U and W you might choose R3
G73 P(start)Q(end) U(finish allowance x)W(finish allowance z)F(feed) is all you need..You need to start the cycle from a place where any return moves will not crash through your work..Hope that helps..

You still haven't stated the model of the Fanuc control. If the control is pre "O" series, the G73 cycle command will be a one block designation with different addresses used to set various parameters.
