AN EXPERIMENTAL STUDY OF THE EFFECT OF WRONG POSITIONING OF TOOL ON TAPER TURNING: MEASUREMENTS, ANALYSIS &

In this empirical study, a mathematical proof and calculations of possible error has been demonstrated when the tool has been set below or above the center of the work piece on an experimental lathe with respect to a taper turning operation. This paper describes the effect of wrong positioning of tool on taper turning operation. Hence our experiment emphasizes practical implementation of taper turning process where irrespective of the job whether it is being made taper or straight, in both case the tool should be positioned at the center of the work piece, neither above or below. Experimental results have shown that a considerable amount of improvement was achieved for the taper ness of workpiece in the taper turning operation. The acceptance of the job depends on the measuring systems w.r.t acceptance criteria (drawing dimensions) with the help of ruby ball (touch probe) which includes the radio and inductive transmission systems in the CNC machines being controlled. Hence PLC programming has been developed which enables us to segregate the job in such a way that if the job is rejected, it will go to reject bin and if the job is accepted, it will go to accept bin automatically
