MECHANICHAL MANUFACTURING

Abstract

Machining by material removal is one of the processes of mechanical manufacturing. This machining represents the search for solutions that allow obtaining a conceivable part at a cost with good performance, by combining information relating to the chronological order of the operations performed, the use of skilled labor, machine tools, tools and equipment requested. This technique also allows us to produce parts with complex shapes and high precision without modifying the characteristics of the machined material. Material removal machining allows for very precise tolerances, which is crucial in many fields, such as aerospace, automotive and tool manufacturing. This process is applicable to a wide range of materials, including metals, plastics, composites and ceramics, making it a versatile technique for many industries. In addition, this method is also used for the repair or refurbishment of damaged or worn parts, thus extending their service life and avoiding the waste of valuable resources. In summary, material removal machining remains an indispensable pillar in modern manufacturing, combining precision, versatility and cost efficiency. This handout entitled "Mechanical Manufacturing" is intended for second-year students of the Academic License in Mechanical Engineering, Mechanical Construction option. It is designed to highlight knowledge of product manufacturing techniques, in particular mechanical products. It is written in a simplified manner with examples introduced after giving notions so that the student can assimilate the content of the course and have a clear vision of its application in the industrial sector. This document is divided into two parts, the first part of which concerns the theory of metal cutting from the point of view of cutting materials, geometry of cutting tools, chip formation mechanism, cutting forces, heating and damage of cutting tools as well as the methodology for choosing cutting parameters. The second part deals with machine tool technology, based on cutting movements, main components and kinematic chains for some machine tools.
