Thus cutting becomes faster, accurate and effortless. Panel saws are used by cabinet shops to easily cut panels, profiles, solid wood, plywood, MDF, laminates, plastic sheets and melamine sheets into sizes or cabinet components. They are also used by sign shops to cut sheets of aluminum, plastic and wood for their sign blanks.
Different wood cutting boards on a store shelf. A knife edge is a delicate structure and can easily be blunted by a too abrasive surface. It can also be chipped if used on a surface that is too hard. A good cutting board material must be soft, easy to clean, and non-abrasive, but not fragile to the point of being destroyed.
The largest machines used in wood processing, often called "Tub or Horizontal Grinders", may handle a material diameter of 2.4 m (8 ft) or greater, and use carbide tipped flail hammers to pulverize wood rather than cut it, producing a shredded wood rather than chip or chunk. These machines usually have a power of 150–750 kW (200–1,000 hp).
Chip formation is part of the process of cutting materials by mechanical means, using tools such as saws, lathes and milling cutters.. The formal study of chip formation was encouraged around World War II and shortly afterwards, with increases in the use of faster and more powerful cutting machines, particularly for metal cutting with the new high speed steel cutters.
Plywood is a common example of a laminate using the same material in each layer combined with an adhesive. Glued and laminated dimensional timber is used in the construction industry to make beams (glued laminated timber, or Glulam), in sizes larger and stronger than those that can be obtained from single pieces of wood.
Lumber can be quickly flat-cut with a side-by-side set of mechanical saws. [3] A slower but sturdier method involves passing the log back and forth over a single saw. To reduce buckling that may occur along the middle of flat-cut boards, the initial cut may be offset from the diameter, and resulting sections cut further before cutting the flitches.

Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde . [ 1 ]
