Responsibilities include:

• Studies drawings and sketches of proposed product and confers with engineering personnel to plan design details and model operation.
• Determines machines, tooling, and sequence of operation necessary to produce model parts, tooling, dies, or patterns, utilizing knowledge of machining and fabricating techniques.
• Lays out reference points and dimensions on assorted materials, such as metals, plastic, and synthetic resins, using measuring instruments and work aids.
• Sets up and operates machines, such as milling machines, lathes, grinders, drill press, punch press, and brake, to produce or modify model parts.
• Fits and assembles parts, using handtools or power tools.
• Wires and solders electrical and electronic connections and components.
• Inspects and tests model or other product to verify conformance to specifications, using precision measuring instruments, such as calipers, gauges, and micrometers, and test equipment, such as multimeter and oscilloscope.
• Suggests structural or operational modifications or reworks component parts as required to ensure performance of equipment or parts meets standards.
• May consult with engineering personnel to evaluate design and performance factors.
• May specialize in fabricating, testing, and adjusting prototype models of electromedical equipment and be designated medical-apparatus model maker.
