The pedal operated machine has been designed and manufactured for the cutting of different metals. The rotary movement of the pedal is becoming an alternative movement (forward and backward) using the four-bar mechanism (HSS, 12 mm and 0.5 mm) to cut materials such as MS, copper, brass, etc. . Bicycle structure as it is developed and manufactured ergonomically. Using this mechanism, a normal average human can cut 20 workpieces (20 mm average diameter) in 30 minutes. The machine has been tested with different metal shafts of 16mm in diameter. The cutting time was recorded at several rpm (100, 150 and 200) for different metals. The obtained data were analyzed and compared with the cutting time required for the electric saw machine and the manual metal saw. The machine has a mechanical advantage of 0.45 (less than one) and a mechanical efficiency of 79%, which indicates that this manual saw machine is more beneficial than the electric or manual machine, since it does not consume electricity and works without Much human input Compared hand operated metal saw.
