Machined parts are used in various fields, ranging from simple metal fasteners to complex aircraft engine components. The core of machining lies in the use of cutting equipment such as milling machines, grinders, and lathes to manufacture specialized parts. Despite their different methods, they all share the same goal: to remove material from a solid block, known as a workpiece, using precision cutting tools. Different methods can be employed to produce machined objects. Manual part processing requires the knowledge of highly trained machinists who manually use machinery such as milling machines to form precise parts through milling. On the other hand, CNC machining utilizes electric CNC machines that autonomously perform the cutting process according to computer-generated instructions.
