lay symbol - surface finish

[Larry1958]

I have a part that has a callout as follows

 

ROUGHNESS 500MIN

LAY SYMBOL X

WAVINESS HT. .010

 

This callout is on a flat surface.

I am going to create a ruled surface and create a finish surface parallel toolpath with a .125 ball e'mill, at .01 deep, with a cusp height of .010. I will use parallel with one angle at 45, then another at 135. This creates a diamond pattern on the surface. Is this the right approach? This is the first time I have seen a surface finish with this callout. Thanks in advance.

Sounds like a way to get there. What about a larger diameter face mill? Could get a decent cross hatch that way.
