It is evident that in all current activities of the civilized human being, all kinds of by-products and manufactured products are present, that is, products that have been obtained from raw materials and through specific processes are modified to create an article of use or else satisfying.
For this reason, and from the Industrial Revolution, the processes by means of which by-products and products are obtained are known as manufacturing processes, and their evolution and study comprise a fertile field for the development of engineers in their various branches.
It is a priority of our times, to promote the improvement of manufacturing processes that allows maximum use of each and every one of the resources involved in the manufacture of products, and thereby seek to improve their quality and costs, as well as obtaining the volumes demanded in the predicted times.
Now, understanding manufacturing processes is not enough; The Industrial Engineer participating in a team in charge of manufacturing projects, must have additional and peripheral knowledge that allows him the optimal link with the areas directly or indirectly related to the product, in order to correctly master the production panorama.
Taking this knowledge to macroeconomic scales, it has been observed that highly industrialized and so-called first world countries owe their success and dominance of international markets to the extensive development of technology.
This research work is prepared with the following main objectives:
- Get involved as students and future Engineers in the business sector Increase our theoretical-practical knowledge in this regard Show a broad overview of the different factors that intervene in the manufacturing process of a product Identify the different Manufacturing Processes that may intervene in the manufacture of a product. Accredit the matter of Industrial Manufacturing I. Carry out the pertinent calculations for planning the production of a certain product. Recognition of the equipment used to make a given product.

CONCLUSIONS
In conclusion, we consider it correct to remember that Manufacturing Processes, being an important part of engineering, are based entirely on the application of scientific, technical and administrative knowledge, focused on obtaining products in optimal conditions of use. Therefore, a level of perfection must be obtained that allows the identification of the pertinent considerations in these processes.
It is essential that the industrial engineer have extensive knowledge in manufacturing processes not only theoretical, but also practical, because it is one of the elements that he will face in his professional future due to the interrelation he has with the other areas of the production companies of goods and because the production department is where the utility is generated and therefore giving quality in the product is important.
