What does a machinist do?

A machinist is someone who uses heavy equipment to cut machinery parts made of different materials including steel, silicon, aluminum, and plastic. Machinist work takes a great amount of focus and precision. Machinists must be able to read mechanical blueprints, make calculations, determine machine speed, and perform precise cuts to create tools, fixtures, building materials, and other products. In addition to creating products based on preset specifications, machinists must also maintain their machines to ensure they cut properly and safely. This means keeping them properly lubricated and regulating their temperature. In many cases, machinists must have a working knowledge of computers which may help them determine cutting patterns and paths.
