The missions of the mechanical manufacturing engineer are deployed from the analysis to the implementation of new systems.
His mission is to create mechanical systems or parts, based on his analyses of the mechanical needs of a company. He supervises both the manufacturing and assembly as well as the maintenance of mechanical systems, and therefore manages the technicians under his supervision, while ensuring compliance with safety measures. https://www.junia.com/fr/fiches-metiers/ingenieur-en-fabrication-mecanique/

Cutting tools are tools used to remove material from a workpiece in the form of chips. They are used in a wide range of manufacturing and machining processes, such as drilling, milling, turning, and grinding. The selection of cutting tools is crucial to the efficiency and quality of the machining process. There are many different types of cutting tools available, each with their own unique characteristics and uses.

Cutting Tool Geometries
Cutting tools for metal cutting have many shapes, each of which are described by their angles or geometries. Every one of these tool shapes have a specific purpose in metalcutting. The primary machining goal is to achieve the most efficient separation of chips from the workpiece. For this reason, the selection of the right cutting tool geometry is critical.
