Set up, operate, or tend machines that cut or slice materials, such as glass, stone, cork, rubber, tobacco, food, paper, or insulating material. Review work orders, blueprints, specifications, or job samples to determine components, settings, and adjustments for cutting and slicing machines. Examine, measure, and weigh materials or products to verify conformance to specifications, using measuring devices such as rulers, micrometers, or scales. Press buttons, pull levers, or depress pedals to start and operate cutting and slicing machines. Start machines to verify setups, and make any necessary adjustments. Feed stock into cutting machines, onto conveyors, or under cutting blades, by threading, guiding, pushing, or turning handwheels. Monitor operation of cutting or slicing machines to detect malfunctions or to determine whether supplies need replenishment. Stack and sort cut material for packaging, further processing, or shipping, according to types and sizes of material. Adjust machine controls to alter position, alignment, speed, or pressure.
