A Cutting Tool Is Any Tool That Is Used to Remove Material

A cutting tool is any tool that is used to remove material from the work piece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, plaining and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools. Grinding tools are also multipoint tools. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip. Cutting tools must be made of a material harder than the material which is to be cut, and the tool must be able to withstand the heat generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the work piece without the rest of the tool dragging on the work piece surface. The angle of the cutting face is also important, as is the flute width, number of flutes or teeth, and margin size. In order to have a long working life, all of the above must be optimized, plus the speeds and feeds at which the tool is run. There are various types of cutting tools are available for various purposes such as linear cutting instruments which include tool bits (single-point cutting tools) and broaches. Rotary cutting equipment which include drill bits, countersinks and counter bores, taps and dies, milling cutters, reamers, and saw blades. Other cutting equipment, such as band saw blades hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. Cutting instruments are often designed with inserts or replaceable tips (tipped tools). In these, the cutting edge consists of a separate piece of material, brazed, welded or clamped on to the tool body. Common materials for tips include tungsten carbide, polycrystalline diamond, and cubic boron nitride. Tools using inserts include milling cutters (end mills, fly cutters), tool bits, and saw blades. The typical tool for milling and drilling has no changeable insert. The cutting edge and the shank is one unit and built of the same material. Small tools cannot be designed with exchangeable inserts. To use a cutting tool within a CNC machine there is a basic holder required to mount it on the machines spindle or turret. The detailed instruction how to combine the tool assembly out of basic holder, tool and insert can be stored in a tool management solution. In India there are many industries which engaged in manufacturing, supplying and exporting of cutting equipment. There are wide varieties of cutting tools are available in the markets like cutter, metal cutting machinery, paper cutting instruments, metal cutting machinery, milling cutter, band saw machines, slitting machines etc. All these cutting tools are used in various purposes in industries as well as for domestic purposes. These cutting tools are available in the markets very easily and also these are not very much costly also a customers can avail these cutting equipments as per the his/her requirements. Also there are many manufacturers who manufactured these cutting tools as per the specific requirement of customers and these can be avail at very cost effective prices also. Source: GOARTICLES
