Formula, Roughness

Straight turning operation is carried out to reduce the diameter of a cylindrical workpiece. It is carried out in lathe with the help of a single point turning tool. The tool and workpiece are mounted firmly on the machine. The workpiece is rotated at certain speed about the machine longitudinal axis (spindle axis). The tool is also fed parallel to the machine longitudinal axis after giving the depth of cut.

Taylor’s Tool Life Formula for Machining
Formula

Formula, Tool Life

Machining is one manufacturing process where material is removed from the workpiece with the help of a cutting tool in order to generate desired feature. The overall machining performance depends greatly on the condition of the cutting tool. In this context, a term “Tool Life” is used that is defined as the duration of time within which a particular cutting tool gives satisfactory performance during machining. If a cutter is
