Quick Return Mechanism (QRM) is a mechanical assembly to form a reciprocating motion that is so designed to reduce the ideal time required for a reappearance stroke.It translates rotational motion into countering motion, but dissimilar to the crank and slider, the onward reciprocating gesture Tall Pier is at a slower proportion than the return stroke.This paper mainly focuses on finite element examination of the QRM for shaper application.

The 3D model of the QRM was modeled in SOLIDWORK 17, and finite element analysis was performed in ANSYS 18.There are three different lengths of connecting rod (link 2) compared to each other.By increasing the crank length, the cutter speed will be increased (i.

e., velocity is directly related to crank length).Ram velocity varies from zero at the beginning, maximum at the middle of the stroke, and zero at the end.

In the numerical analysis Sundials when the crank length decreases the total deformation decreases and vice versa for cutting speed.
