Introduction

The purpose of this course work is to design and study the mechanism of a horizontal forging machine.

Speed and Acceleration Plan

The velocity plan is a graphical image in the form of a beam of absolute velocities and points of links and segments connecting the ends of the beams, which are the ratio of the velocity of points in a given position of the mechanism.

Defining an acceleration plan is similar to defining a velocity plan.

Speed and acceleration plans will be considered for the tenth position.
