Investigation of variation in offset values of different sections of machining elements along the central axial line

Abstract

Eccentricity is defined as deviation from the circular path and it occurs due to clamping deviation or geometric imperfection when machining elements revolves around the line parallel to the machining element axis, but not around the machining element axis. In this paper, the variation of offset values along the central axial line of different small sections of spindle, tool holder and milling cutter was explored. This work was undertaken by the observation that eccentricity implies adverse impact on the material properties, tooling properties, machining elements, machine system etc. The problem solution was found out by measuring the whole body of spindle, tool holder and milling cutter with Swiss Dial Gauge after dividing them into small sections along the z level axis. After measurement, analysis was done of the recorded data on software’s by illustrating their actual profiles and variation along the Centre line of small divided sections at different orientations. After analysis, we might get the eccentricity of one part with different offsets in z level through offsets in x and y directions and profiles of elements exhibiting less offset values. This work can find its importance in various industries where milling machines are used for machining jet parts, automobile parts and many other etc.
