What is the General Procedure of Designing Machine Component?

In Designing a machine component,there is no rigid rule.The problem may be attempted in several ways.Every machine design engineer tried at his levelbest to overcome the possible problems,but machine designing is a continious process.

However,the general procedure to solve a design problem is as follows.

01)First of all make a complete statement of the problem,indicating the purpose for which the machine is to be designed.

02)Select the possible groups of mechanisms which will give the desired motion.
03)Find the forces acting on each member of the machine and the energy transmitted by each member.

04)Select the best material suited for each member of the machine.

05)Find the size of the each member by considering the forces acting and the permissible stresses for the material used.It should be kept in mind that each member does not deflect or deform than the permissible limit.

06)Modify the size of the member to agree with the past experience and judgement to facilitate manufacture.

07)Draw the detailed drawing of each component and the assembly of the machine with complete specification for the material and manufacturing process suggested.

Follow all the above points to design a best quality machine, and be the best design engineer.
