Will “CNC Drilling Operator (Computer Numerical Control Drilling Operator)” be Automated?

Core Skills & Abilities

• Perform minor assembly, such as fastening parts with nuts, bolts, or screws, using power tools or hand tools.

• Change worn cutting tools, using wrenches.

• Select and set cutting speeds, feed rates, depths of cuts, and cutting tools, according to machining instructions or knowledge of metal properties.

• Study machining instructions, job orders, or blueprints to determine dimensional or finish specifications, sequences of operations, setups, or tooling requirements.

• Operate tracing attachments to duplicate contours from templates or models.

• Lay out reference lines and machining locations on work, using layout tools, and applying knowledge of shop math and layout techniques.

• Observe drilling or boring machine operations to detect any problems.

• Turn valves and direct flow of coolants or cutting oil over cutting areas.

• Sharpen cutting tools, using bench grinders.

• Verify that workpiece reference lines are parallel to the axis of table rotation, using dial indicators mounted in spindles.

• Lift workpieces onto work tables either manually or with hoists or direct crane operators to lift and position workpieces.

• Install tools in spindles.

• Move machine controls to lower tools to workpieces and to engage automatic feeds.

• Position and secure workpieces on tables, using bolts, jigs, clamps, shims, or other holding devices.

• Verify conformance of machined work to specifications, using measuring instruments, such as calipers, micrometers, or fixed or telescoping gauges.

• Operate single- or multiple-spindle drill presses to bore holes so that machining operations can be performed on metal or plastic workpieces.

• Establish zero reference points on workpieces, such as at the intersections of two edges or over hole locations.
