摘要：The objective of this work is to automate the conventional power hacksaw machine in order to achievehigh productivity of work-pieces than the power hacksaw machine using Microcontroller. The automated machineacquires two inputs from the user namely the number of pieces to be cut and the length of each piece that is required tobe cut. The inputs are given by the user with the help of a keypad and an LCD display, which will help the user toverify the data given by him. The operator need not measure the length of the work-piece that is to be cut and to loadand unload the work-piece from the chuck each time after a piece has been cut. After acquiring the two inputs from theuser, the machine automatically feeds the given length of work-piece in to a chuck and starts to cut till the givennumber of work-pieces has been cut. The machine feeds the work-piece with the help of a conveyor, which is driven bya DC motor and an IR sensor ensures that the feeding stops when the specified length has been reached. A pneumaticcylinder is used for holding the work-piece when cutting operation is done. An AC motor is used to bring about thereciprocating motion required for cutting the work-pieces. There is a self-weight attached with the reciprocatingmechanism to provide the necessary downward force required for penetration of hacksaw blade in to the work-piece.When a single piece has been cut, a limit switch will get triggered by the self-weight mechanism, which is sensed bythe microcontroller to start the cyclic operation again provided if the specified number of work-pieces has not been cut.
