All surfaces are surface testing by 9 by changing the diameter of the cavity is 0.1, 0.5, and 1 mm cavity pitch modification by measuring the diameter is the distance equal to 2, 4, 6 mm with a depth of 1 mm for every surface.
Textured surface by all nine test by changing the diameter of the cavity is 0.1,0.5,1 mm. And adjust the spacing of the cavity was measured by a distance equal to the diameter 2,4,6 mm. A. the depth of 1 mm. surfaces.
The surface of all 9 surface by test by changing the diameter of the center cavity is 0.1 0.5 1 mm,,, And modify the distance measured by the distance cavity diameter equal to 2 4, 6 mm depth, only with 1 mm every surface.
