Cutting tool has a simple shape, but the feed motion is complex; cutting tool is fed along a contour thus creating a contoured shape on the workpiece. For profiling, special lathes or devices are required. V.
Control (CNC). Amongst the machine tools, lathes are most versatile and widely used. Here automation of lathes only have been discussed. The conventional general purpose automated lathes can be classified as,. (a) Semiautomatic : • capstan lathe (ram type turret lathe). • turret lathe. • multiple spindle turret lathe.
LATHE. Definition. Lathe is a machine, which removes the metal from a piece of work to the required shape and size. Common types of lathes: Engine Lathe: The most common form of lathe, motor driven and comes in large variety of sizes and shapes. Bench Lathe: A bench top model usually of low power used to make
