Lathes
Lathes have been used for thousands of years to shape round objects by turning material on an axis while forcing material against a sharp tool. Lathe and Turning Machine Tool Setters, Operators, and Tenders (Metal and Plastic) set up, operate, or tend lathe and turning machines to turn, bore, thread, form, or face metal or plastic materials, such as wire, rod, or bar stock to form all types of parts. Lathe machined plastic and metal parts can be found in products ranging from motorcycles to guitars to artificial hearts.
Lathe and Turning Machine Tool Setters, Operators, and Tenders can be separated into two groups—those who operate manual lathes and those who operate computer numerical controlled (CNC) lathes. Employers often specify manual or CNC in the job title. Setup workers prepare the machines prior to production and may adjust the machinery during its operation. Operators and tenders primarily monitor the machinery during its operation, sometimes loading or unloading the machine or making minor adjustments to the controls. Many workers both set up and operate equipment. Setup workers plan and set up the sequence of operations according to blueprints, layouts, or other instructions. They adjust the speed, feed, and other controls, choose the proper coolants and lubricants, and select the instruments or tools for each operation.
