The ceramic tile cutter works by first scratching a straight line across the surface of the tile with a hardened metal wheel and then applying pressure directly below the line and on each side of the line on top. Snapping pressure varies widely, some mass-produced models exerting over 750 kg.
Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine.. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding.
Surface grinding is done on flat surfaces to produce a smooth finish. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles ( grinding wheel ) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

To quantify a cutting edge the following parameters are used: cutting edge radius for symmetric edges; cutting edge ellipse axis for asymmetric edges; factor K, this is the relation between Sγ and Sα. This can also be calculated by the ratio of the two axis of the ellipse. This factor describes the form of the cutting edge.
Steel cut-off saw for workshop use Cutting heavy steel cable with a Husqvarna freehand saw US Navy diver preparing to use an abrasive saw for underwater salvage. An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw (a kind of power tool) which is typically used to cut hard materials, such as metals, tile, and concrete.
