Steady rests are additional median, supports, used in lathe machine for long willowy work to halt it from being bent by the action of the cutting forces. When the length and stiffness of a work piece make it laborious to machine without distorting or deflecting the job, many industrialist turn to the steady rest as a work piece support device. This is mainly veracious for long rod, shafts and homogeneous parts used in industries or heavy equipment demand. Steady rest can be mounted and used to superior advantage on most types of lathes for lengths, face and, centering, internal turning, plunge cutting, boring, andparting off etc. In this paper the effort is being made to modify a Steady Rest to reduce the machining time and setup time in the process. The addition of machining time and setup time gives the total machining time of the process. So, if the set up time will raise, unfortunately total machining time will increase. To make operations fast and accurate there are many attachment used in lathe machines. To reduce the set up time and increase accuracy one of the accessories is generally used which is called as Steady Rest.
