INTRODUCTION OF CHAIN DRIVE:
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle. It is also used in a wide variety of machines besides vehicles and mechanisms. The power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system.
The chains as part of mechanism so that a non uniform motion can be obtained from a design point of view, chains are low in cost, reliable as machine element, and readily adaptable to varity of tasks. The trick when using chains to obtain a non uniform motion is to fasten a pin (or) a slider to a chain link and then arrange the chain sprockets in such away that a desired output motion is obtained.
Chain Driven Slider mechanism utilizes advanced
mechanisms. Chain drive mechanisms are very flexible. In Chain Driven Slider, that is, a translating slotted member (the slider) is driven by a roller (or)
pin fastened to a chain. The chain is guided by two sprockets(1&2).The
velocity of the yoke is uniform when the pin moves from sprockets 1 to 2 and gear 2
to 1.The motion of driving pin fastened to a chain with translating slotted
member (the yoke)from sprocket top point to bottom point and bottom point to top
point is sinusoidal. It is possible to vary the size of the gear for this
mechanism and in the cases different constant velocities can be obtained.

ADVANTAGES:
- While compare to existing mechanism it is easy to Cut (or) Shape large parts without limitations by adjusting sprockets at different length and position according to need.
- Easy to maintain and operate.
- Portable and their is no need of separate arrangement.
- Initial cost less while compare to other mechanism.
PROBLEM IN EXISTING SYSTEM:
- Unsuitable for generating flat surfaces on very large parts because of the limitations on the stroke and over hang the ram.
- Shape (or) Cuts only one piece of stock at a time.
- Need more maintenance and periodic service.
- Initial cost is high.
