The primary objective of this paper is to design and develop the sheet metal cutting machine for circular profile using continuous piercing operation. In order to obtain circular cutting of sheet of any dimensions, along with adjustable sheet handling setup for getting different size of circular profiles. Which result in more flexible use of machine, reduction in cost and increase in productivity. In many industries the circular profile of sheet metal is achieved by punching machines, CNC machines and by radial drilling machine. In case of small and medium scale industries using separate machines for different sizes of sheet and applications is not possible. This paper deals with design and development of sheet metal cutting machine for circular profiles using piercing operation. Instead of using punch, there is reciprocating single point cutting tool which is operated by Cam and follower mechanism, along with separate adjustable sheet holding arrangement, that enable to adjust the diameter of circular profile. The desire operation i.e., circular profile is achieved by combination of two mechanism, one is reciprocating motion obtained by cam and follower and the second mechanism is used to rotate and hold the sheet.
