Open: Mechanical Workshop Technology for Mechanical Engineering Technicians
Premium Membership Minimum Required


Few people outside the engineering industry appreciate the contribution of modern technology in meeting the demands and needs of our present-day civilization. The study of the scientific principles underlying the art of engineering manufacture is the study of Workshop Technology, an all-important subject when one considers that it is skill in engineering manufacture that makes possible a standard of living beyond the wildest expectations of the previous generation.

It is the emergence of the machine tool within the last 150 years that has made possible the ability of the civilized world to provide the essentials of existence to its own rapidly growing population, and perhaps of greater importance, to make available modern techniques and processes to the underdeveloped territories of the world.

The need for efficient and well-trained mechanical engineering technicians is great. The stated aim of the scheme of work contained in the Mechanical Engineering Technicians' Course is to meet the needs of those who aspire to supervisory duties, shop and process control, drawing office practice, plant maintenance and other forms of responsibility.
