Study of Comparison between shaper & Planer with Modified tool head for the enhancement in productivity & energy conservation

Tools are the essential part of a manufacturing workshop. Shaper & planer are one of them which utilize these tools to develop different magical jobs. Flat surfaces are machined by these machine tools.. They have reciprocating motion for a single point tool and the job. During the forward stroke of the tool, machining will take place while in the return stoke, the tool will be idling. These two strokes are known as forward stroke & idle stroke respectively. The quick return mechanism of these machines; reduce the ineffective time (i.e. the idle stroke time when no machining takes place) and wastage of energy. An idea has been suggested on reducing the idle stroke time, with modified tool post, two clapper boxes and with two tools. This arrangement ensures material removal during the return stroke also. In this paper, special care is taken to save energy, machining time and improve the productivity.
