This is the process where a machinist will produce a large quantity of a specialized part or item. They use their knowledge of metal and what metal is made of, and their ability with machine tools to create the necessary output that is designed by strict and concise specifications.
Before the machinist even starts his work, he must prepare the operation by setting up the machine with the programming that was previously downloaded into the control of the machine. Before they even attempt anything with the machine, they look at and review blueprints and written specifications, so as to know exactly how the process is to proceed. Once they determine this, they calculate where to cut the hole or holes, and how fast they need to feed the metal they are using into the machine, and how much metal has to be cut away. They then prepare the metal, so they know where to make the holes or cuts.
After the machinist prepares the metal for cutting, he places the metal into a machine, sets the controls and makes the cut. During the cutting sequence, he monitors the feed and speed of the machine to make sure everything is working correctly. For what they do machinist do not necessarily use metal, they also use steel, bronze, graphite, glass, and plastics.
