Fig. 2 presents a schematic of the grinding system motion analysis in grinding biconical surface using STS-DGW. The biconical optics is fixed on the workpiece spindle, which rotates at an angular speed ω s, and moves along the positive or negative X-direction because the biconical optics possess different curvatures in X and Y directions. The diamond grinding wheel is mounted on the Z-axis ...

Once you have the back of the mirror ground flat through 220 and the face reasonably flat, you're ready to start roughing the curve into the mirror. I recommend #60 carborundum for rough grinding. By the way, as in all optical work, be sure that you always maintain bevel on the edge of the mirror throughout grinding.

I have high hopes for this mirror. It was built with the new hexagon molding technique and new edge grinding machine. I am calling it my second generation hexagone back blank. This one has far fewer air bubbles in it than the first prototype …

Apparatus for simultaneously performing rough and fine grinding operations on the surface of a work piece. The apparatus includes a cup-shaped grinding tool having rough and fine grinding rings coaxially mounted for rotation about their common axis. The work piece to be surfaced is supported for movement along a curved path such that the work piece will intersect the grinding tool as it moves ...

Generation The first step in the lens manufacturing process is generation. This process will 'generate' the shape of the lens into the blank, getting close to its final shape, size, and curvature. Although an outdated process, one generation technique …

If the mirror's curve is deepened from a sphere to a parabola then the light focuses perfectly, limited only by diffraction. The amount of glass to be removed is a few millionths of an inch. The formula is r^4/(8R^3) (r=mirror radius, R=radius of …
