-
Inspect sample workpieces to verify conformance with specifications, using instruments such as gauges, micrometers, and dial indicators.
-
Crank machines through cycles, stopping to adjust tool positions and machine controls to ensure specified timing, clearances, and tolerances.
-
Adjust machine controls and change tool settings to keep dimensions within specified tolerances.
-
Start lathe or turning machines and observe operations to ensure that specifications are met.
-
Compute unspecified dimensions and machine settings, using knowledge of metal properties and shop mathematics.
-
Clean work area.
-
Refill, change, and monitor the level of fluids, such as oil and coolant, in machines.
-
Select cutting tools and tooling instructions, according to written specifications or knowledge of metal properties and shop mathematics.
-
Program computer numerical control machines.
-
Replace worn tools, and sharpen dull cutting tools and dies, using bench grinders or cutter-grinding machines.
-
Turn valve handles to direct the flow of coolant onto work areas or to coat disks with spinning compounds.
-
Lift metal stock or workpieces manually or using hoists, and position and secure them in machines, using fasteners and hand tools.
-
Install holding fixtures, cams, gears, and stops to control stock and tool movement, using hand tools, power tools, and measuring instruments.
-
Move controls to set cutting speeds and depths and feed rates, and to position tools in relation to workpieces.
-
Mount attachments, such as relieving or tracing attachments, to perform operations, such as duplicating contours of templates or trimming workpieces.
-
Study blueprints, layouts or charts, and job orders for information on specifications and tooling instructions, and to determine material requirements and operational sequences.
-
Position, secure, and align cutting tools in toolholders on machines, using hand tools, and verify their positions with measuring instruments.
-
Move toolholders manually or by turning handwheels, or engage automatic feeding mechanisms to feed tools to and along workpieces.
