(LATHE/WOOD TURNING, JOINERY, CNC CUTTING, CARVING, WOOD BENDING)

LATHE/WOOD TURNING Woodturning is a form of woodworking that is used to

create wooden objects on a lathe.  There are two distinct methods of turning wood: spindle

turning and faceplate turning. Their key difference is in the orientation of the wood

grain, relative to the axis of the lathe. This variation in orientation changes the tools and techniques used.

In spindle turning, the grain runs lengthways along the lathe bed, as if a log was mounted in the lathe. Grain is thus always perpendicular to the direction of rotation under the tool.

In bowl turning, the grain runs at right angles to the axis, as if a plank were mounted across the chuck. When a bowl blank rotates, the angle that the grain makes with the cutting tool continually changes between the easy cuts of lengthways and downwards across the grain to two places per rotation where the tool is cutting across the grain and even upwards across it.

JOINERY Joinery is a part of woodworking that involves

joining together pieces of timber or lumber, to produce more complex items.

Some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements.

The characteristics of wooden joints - strength, flexibility, toughness, appearance, etc. - derive from the properties of the materials involved and the purpose of the joint.

Therefore, different joinery techniques are used to meet differing requirements.

For example, the joinery used to construct a house can be different from that used to make puzzle toys, although some concepts overlap.

CNC CUTTING CNC means Computer Numerical Control. This means a

computer converts the design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material.

In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine by a post processor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools – drills, saws, etc., modern machines often combine multiple tools into a single "cell". In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.

CNC ROUTER A CNC router is a computer controlled cutting machine related to the hand held router used for cutting various hard materials, such as wood, composites, aluminium, steel, plastics.

 CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control.

• A CNC router typically produces consistent and high-quality work and improves factory productivity. Unlike a jig router, the CNC router can produce a one-off as effectively as repeated identical production.

CARVING Carving is the act of using tools to shape something

from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and yet soft enough for portions to be scraped away with available tools.

Wood carving is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural ornamentation of a wooden object.
