Machine Tool
A). Machine tool is any of a wide variety of tools, usually large, rugged, and power driven, for cutting, shaping, or forming metal. Precision of operation makes it possible to produce hundreds of identical parts, all so much alike that they may be freely interchanged or substituted in assembly or repair, without hand-fitting.
B). Machine- tools are known to serve four main purposes: 1) they hold the work or part to be cut; 2) they hold the cutting tool (or tools); 3) they impart to the cutting tool or work the motion required for cutting or forming the part; 4) they regulate the cutting speed and the movement between the tool and work.
The most common machine-tools are lathes, which perform cutting operations mostly, milling machines, drilling machines and grinders.
C). Lathes. In addition to the engine lathe, there are quite a number of higher-production lathes, including tracer lathes, Swiss-type automatic screw machines, turret lathes, and single- and multispindle automatic lathes. Tracer lathes are similar to the engine lathe, but the tool path may be guided by a template-template type, tracing the operation is automatic, but the operator has to position the tracing-tool unit for each cut and return it to the starting position for the next cut. Swiss-type automatic screw machines are designed to produce small-diameter parts, such as shafts for clocks or watches. The cutting tools are arranged in a radial pattern around the workpiece. A unique feature is that the stock can be fed longitudinally while it is being cut to generate curved surfaces. Accuracies on small production parts may be held to 0.0005 inch (0.0013 mm).
A turret lathe is made with two turrets, one at the tailstock end of the machine and the other mounted on the cross-slide. Each of the tools on either of the turrets can be indexed (rotated) and locked into position and then brought up to the stock for the desired cut. On a manual-type turret lathe, the operator does the indexing, but the tools are fed into the workpiece by power.
"Single-spindle automatics" are turning machines whose movements are directed by gears and cams. Automatics can be used for bar or individual pieces held in a chuck, which are then referred to as "chuckers." These machines are fast but are economical only for large production runs. One person can operate two or more machines of this type simultaneously. Multispindle automatic lathes are built somewhat similar to the single-spindle automatics but are equipped with four, six, eight, or more spindles. Either the bar stock or individual pieces may be held in the chucks. After the necessary cuts are made at each station, all the chucks rotate, or index around. This continues until all workpieces have been machined. A newer concept in turning is the numerically controlled lathe with a built-in computer.
D). Transfer Machines. The highest degree of automation in metalworking production is made possible by the transfer machine. A transfer machine is essentially a combination of individual machine tools arranged in the required sequence, connected by material-handling or transfer devices and integrated by interlocking controls. On these specially built machines, hundreds of operations are performed and inspected automatically. On large parts such as automotive engine blocks, part-turnover and orienting devices often are used between groups of work stations to present new surfaces to the horizontal, vertical, or angular machining units.
