machine tools are powered tools

Parts Processing and mass processing in factory, can process a variety of workpieces, include Auto parts, Mechanical parts, gearwheel , special-shaped parts, Roughing and fine machining and Mold Manufacturing.

The different types of milling cutters are milling machines and end mills. Milling machines shape a surface by using sharp cutting teeth to rotate against the work piece. An end mill is more common and is able to drill directly into the workpiece.

cutting speed is a combination of depth of cut and feed.

The tool post allows the user to control a cutting tool (such as a chisel) more accurately - to produce better results.

The tool post holds the lathe tools that will be required for each cutting operation required in that part of teh production process. Each post can hold up to four differing tolls - example. Facing tool, knurling tool, long reach internal cutter and then a parting tool. The tool post rides on the saddle on a horizontal plane and the in a cross feed. Most tool feeds can be set to automatic where cutting speed is set and the movement of the post on the saddle automated

It depends on how big it is and what it is made to do. You can get some small home wood working CNC machines for making decoratoive patterns and such for just one or two thousand dollars, or you can get very complex machines for making much larger industrial parts that could cost hundreds of thousands of dollars or more, and probably everything in between.

functions of saw varies on the kind of saw you are using. some saws are for cutting hard things down like for example ... trees. you can also use a saw for cutting hardthings like wood.

the size of a lathe can be described by either of the following ways.

1.DISTANCE BETWEEN THE TWO DEAD CENTERS.

2.SWING RADIUS. IT'S THE DISTANCE MEASURED FROM THE SADDLE/CARRIAGE TO THE AXIS OF THE SPINDLE.

The laser tool for cutting has different capabilities than other tools. it's noncontact cutting and small beam diameter (0.007 inch typical) means that it can cut intricate shapes and small features. Mechanical tools with small diameter endmills must run slowly and be careful not to break the tool or heat it too much. You can make intricate parts, such as machine components.

Lasers can also cut materials that would otherwise wear down tooling. Laser cutting carbon steel and stainless steel is commonly done with laser because it costs less than replacing tooling on a CNC machine, and it can be much faster. You can make quarter inch sheet metal parts used in stainless steel tools.

Lasers can cut materials and leave a smooth or polished edge, thus remove a secondary process for grinding, such as that caused by a plasma cutter that leaves a rough edge, or a router that leaves a rough edge. You can make point of purchase displays made of thick polished acrylic.

A lathe is an in the first instance an engineering machine used for turning metals into specific shapes and diameters, adding threads for screw, creating threads for bolts, boring .

Woodlates (their predecessor) turning bowls , cutting threats on wood, convex and concave shapes

Machine tools are faster and more repeatable than manual labor. They also remove the operator from close proximity to hazardous conditions.

Laser cutting machines cut through a large variety of materials, but there are several laser technologies. CO2 laser can cut organic materials like wood, paper, cardboard, fabric, acrylics and plastics.

A block and tackle magnifies the pulling force applied to rope.

This is useful for moving heavy objects, lifting heavy objects, etc.

A good Example is all the old sailing ships like in The movies "Pirates of the Caribbean" used block and tackle to move and trim the sails.

This is still in use by window washers on skyscrapers to exercise machines.

post processor is the software which converts CAM files into NC machine code files.

role of mechanical engineer in construction is to do design calculations, drawings, and do all the mechanical work in proper way ti do hings in roper way

A simple machine makes work easier by reducing the force which it takes to move something. Also it makes life eaiser, but taking shortcuts does not always help.

A band facer is a taping machine that carries a roll of plastic for edging composite wood surfaces. Cheap furniture is often made of composite woods like K3, medite, chipboard and other particle boards. The bandfacer uses hot glue to attach the plastic band to the exposed edge of such panels.
