Saw Pe Tha
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutting
Cutting is the separation or opening of a physical object, into two or more portions, through the application of an acutely directed force. Implements commonly used for wikt:cut, cutting are the knife and saw, or in medicine and science the scalpel and microtome. However, any sufficiently sharp object is capable of cutting if it has a hardness sufficiently larger than the object being cut, and if it is applied with sufficient force. Even liquids can be used to cut things when applied with sufficient force (see water jet cutter). Cutting is a compression (physical), compressive and shearing (physics), shearing phenomenon, and occurs only when the total stress (physics), stress generated by the cutting implement exceeds the ultimate Strength of materials, strength of the material of the object being cut. The simplest applicable equation is: \text = or \tau=\frac The stress generated by a cutting implement is directly proportional to the force with which it is applied, and in ...

Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Saw Set
A saw set is a tool or part of the tool kit for tuning saw blades. It adjusts the ''set'', or distance the saw tooth is bent away from the saw blade. The magnitude of set determines the cut width and prevents the blade of the saw from binding in the wood. Purpose When the teeth of a saw are formed from the body, they are in line and the same thickness as the blade immediately behind them. A saw with this configuration is described as having 'no' or '0' set. To prevent the body of the blade binding and for other enhancements to the cutting action, the teeth can be set (angled out) from the blade. Teeth can be set in several patterns: single-sided set, alternating set or a patterned set. Most Western and Asian handsaws use an alternating set, whereby a tooth is set the opposite direction from the preceding one. Specialized tools like veneer saws or flush-cut saws may be set only to one side. Some hacksaws and machine saw blades have patterned sets that may require specially de ...

Chisel
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chiselling use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material. A gouge (one type of chisel) serves to carve small pieces from the material, particularly in woodworking, woodturning and sculpture. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section. Etymology ''Chisel'' comes from the Old French ''cisel'', modern ''ciseau'', Late Latin ''cisel ...

Ripsaw
A ripsaw (or rip saw) is a wood saw that is specially designed for making a rip cut, a cut made parallel to the direction of the wood grain. Design The cutting edge of each tooth has a flat front edge and it is angled backward by about 8°, in contrast to a crosscut saw, which has teeth angled backward by about 15°. With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming chisel-like cutting surfaces, whereas crosscut teeth are sharpened at an angle, so that each tooth has a knife-like cutting point in contact with the wood. This design keeps the saw from following grain lines, which could curve the path of the saw: by acting like a chisel, the saw can more easily cut across deviating grain lines, which is necessary if a straight cut is to be achieved. This feature enables the orthogonal cutting edge to efficiently transport wood-chips from the kerf, allowing subsequent teeth to perform a more effective cut. It is possible to see t ...

Rake Angle
Rake angle is a parameter used in various cutting and machining processes, describing the angle of the cutting face relative to the work. There are three types of rake angles: ''positive'', ''zero'' or ''neutral'', and ''negative''. * Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side. * Zero rake: A tool has a zero (or neutral) rake when the face of the cutting tool is perpendicular to the cutting edge at inner side. * Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: * Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. * Reduce cutting forces and power requirements. * Helps in the formation of continuous chips in ductile materials. * Can help avoid the formation of a built-up edge. Negative rak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millimetre
330px, Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales. The microwave is between 1 meter to 1 millimeter. The millimetre (American and British English spelling differences#-re, -er, international spelling; International System of Units, SI unit symbol mm) or millimeter (American and British English spelling differences#-re, -er, American spelling) is a Units of measurement, unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre. One millimetre is equal to micrometres or nanometres. Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is equal to exactly (≈ 0.03937) of an inch. Definition Since 1983, the metre has been defined as "the length of the path travelled by light in vacuum during a time interval of of a ...

Abrasive Saw
__NOTOC__ 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. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting. These saws are available in a number of configurations, including table top, free hand, and walk behind models. In the table top models, which are commonly used to cut tile and metal, the cutting wheel and motor are mounted on a pivoting arm attached to a fixed base plate. Table top saws are often electrically powered and generally have a built-in vise or other clamping arrangement. The free hand designs are typically used to cut concrete, asphalt, and pipe on construction sites. They are designed with the handles and motor near the operator, with the blade at the far end of the saw. Free hand saws ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
