In this machine, the workpiece is kept stationary while the tool is rotated according to the required …show more content…

Taper Turning by Swiveling the Compound Rest – It is done by rotating the workpiece on the lathe axis and feeding the tool at an angle to the axis of rotation of the workpiece. Taper Turning by Taper Attachment – The tool is fed in a straight path that is kept at an angle to the axis of rotation to the workpiece. A.1.3. Limitations of a Lathe Machine Even though many operations can be performed on a Lathe machine, it has a few limitations as well • Most operations require extra fittings and attachments which increases the size of a machine that is huge in itself. This decreases the mobility of the machine. • Manual Lathes require constant supervision and precise control of the machine which is highly unlikely. • Only specific shapes and structures can be made by using a Lathe Machine. • Boring process cannot be performed. • The machine requires constant maintenance due to the large number of parts. • Computer Numerical Controlled Lathes are expensive. • Fewer workers are required to operate CNC machines compared to manually operated machines.

This machine was soon replaced because modernization in technology which “offered real benefits to workers” when before, machines were “relatively slow, unsafe, and physically demanding” (131). In other words, automation restructured American economy after World War II and served to be the main tool for manufacturing operations in which was followed by many other industries for fifteen years.
