A method of preparing a plurality of workpieces for concurrent cutting using a stone cutting machine is disclosed. Each workpiece can include a stone slab that has two parallel faces and one or more edges, a substrate that is bonded to a first face, and a substrate that is bonded to a second face of the stone slab. The stone cutting machine can have a plurality of stone cutting elements and it can be configured to concurrently create a plurality of stone cuts. The method can include: providing a plurality of workpieces; and positioning the plurality of workpieces by placing a set of shims between adjacent pairs of workpieces. The set of shims can be placed to compensate for variations in workpiece thickness and/or to position each of the workpieces with one edge of each stone slab in relative alignment with one of the stone cutting elements.

Methods are disclosed for determining mounting locations of ingots on a wire saw machine. The methods include measuring a test surface of a test wafer previously sliced by the wire saw machine from a test ingot to calibrate the system. A magnitude and a direction of an irregularity of the measured test surface of the test wafer is then determined. The mounting location is then determined for another ingot to be mounted on the ingot holder based on at least one of the magnitude and direction of the irregularity of the measured test surface of the test wafer.

A lightweight artificial stone system comprises a plurality of artificial stones, each of the artificial stones formed of at least some portion of cement, expanded glass, and styrene, the lightweight artificial stones having a density in the range of between about 30 and 70 pounds per cubic foot, each of the stones having six sides and including a first height dimension and a second width dimension, each of the height and width dimensions having a length unit being substantially a multiple of two, each of the stones having four ninety degrees corners and four of the six sides having a smooth surface to provide tight, cement-free seams between adjacent stones, the tight, cement-free seams inhibiting viewing of structure behind said plurality of artificial stones, each of the stones being of such a light weight so as to be held in position in the system by a lath-less and cement-free adhesive.

A method that accurately cuts mother rod lenses and increases production yield. The method includes arranging the mother rod lenses such that the optical axes of the mother rod lenses are parallel to one another, forming a lens block having perpendicular first and second side surfaces to integrally hold the predetermined mother rod lenses, arranging the lens block at a predetermined position, emitting laser beams respectively toward the first and second side surfaces, receiving reflection lights of the laser beams with first and second screens, respectively, adjusting the perpendicularity of the side surfaces relative to a cutting surface of the cutter such that the reflection lights of the side surfaces hit base positions on the first and second screen, and cutting the lens block and the mother rod lenses with the cutter to produce a plurality of rod lenses.

A versatile apparatus for both cutting and grinding, lapping and polishing solid material to produce thin section specimens for analysis and quality control is disclosed herein and includes a support base upon which a quill assembly is mounted. The quill assembly is provided for imparting longitudinal movement to a power-driven rotationally movable spindle, grinding wheel, and cutting wheel, the latter two being connected with the spindle for rotational movement therewith. In this regard, the apparatus includes a differential screw and annular micrometer dial for effecting accurate longitudinal adjustment of the spindle. A sliding cross-plate is also mounted on the aforestated support base and is designed to be manually moved both toward and away from the grinding and cutting wheels. A specimen holder removably mounted on the sliding cross plate is designed to bring a pair of spaced apart specimens into contacting engagement with the wheels whereby one of the specimens will be in contacting engagement with a corresponding one of said wheels when the cross plate is moved toward the latter.
