Week 12 (Semester 2): Final prototype

the final method is constructed and been adjust for the best result. this are some of the works or result of construction of this machine :

the heavy duty induction motor will drive the metal blade by using wheel and axle method and timing belt. 

this roller is used to rotate the blade inside the box to crush the plastic bottle.

bearing is used to give the smoothest rotation to the blade.

Week 11 (Semester 2) : New method

new method by using titanium rotation blade

the design of new blade

after the failure, i have to make a lot of changes to this machine to make it works. the  new method have been found to shred the plastic bottle. by using the rotation blade produces using titanium will make the plastic bottle can cut into small pieces. to make this blade function it will take a lot of time because too much procedure have to take in action to avoid another failure

Week 10 (Semester 2) : Failure

the final part is mount to the project and be tested.

this kind of method have bring failure to this machine. the plastic bottle cannot be shred by using this method due to the hardness of the plastic bottle itself. as we know, plastic bottle are organic polymeric materials consisting of giant organic molecules. so it hard to cut or shred the plastic bottle due to his physical condition. the task was failed because when the grass cutter blade hit the plastic bottle to cut it, the grass cutter blade cannot cut the plastic bottle and the force given by the induction motor make the grass cutter blade force itself to cut it and at last the grass cutter blade is crooked and hit the body of part A and everything is disintegrate. the result of this kind of method is a failure.

the blade hit the body of Part A and crooked.after the failure the blade cannot be used anymore

Week 9 (Semester 2) : continuous project

the body of part A is finish and fitted.
