INTRODUCTION-:
Today connecting rods are best known through their use in interal combustion piston engines such as automotives engine.
In a reciprocating piston engine, the connecting rod or conrod connects the piston to crank or crankshaft.
Together with crank, they form simple mechanism that converts reciprocating motion into rotating motion.
connecting rods may also converts rotating motion into reciprocating motion.
These are of a distinctly different design from earlier forms of connecting rods,used in steam engines and steam locomotive.
EQUIPMENTS-:
CNC MACHINE-:N C machining has completely changed the appearance of the entire industry.
It has impacted almost every aspect of manufacturing –accuracy repeatedly, flexibility and economics in a profound manner.
Cnc capable of performing several different operation such as milling,drilling,reaming,tapping,boring,facing,and similar operation.
it has automatic tool changing capability.
It has another feature pallet suttle means-it has two ore more pallets that can be presented to cutting tool.
cnc machine is operate by setting a program.
About process-
Forging taken from the store.
Double disc grinding operation is done(DDG-R).
BHR and BRB operation is done.
After that BHD process take place.
Next process is BHT.
In next step product goes to alfing chamber.
After that torquing process is done.
In next process fine boring is takes place.
And then again,double disc grinding is done(DDG-F).
Then bush press occurs.
Next process is honning.
At the end washing and packing take place.
