• Shape steel, aluminum, titanium, plastic, silicon and other materials.
• Determine how fast or slow work piece is fed into machine.
• Determine how much material to remove.
• Select tools and materials for the job.
• Plan the sequence of cutting and finishing operations.
• Mark the work piece to show where cuts should be made.
• Position work piece on the drill press, lathe, or milling machine.
• Monitor and control feed rate and speed.
