Drilling and Boring Machine Tool Setters, Operators, and Tenders, Metal and Plastic

01

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

02

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

03

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

04

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

05

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

06

Change worn cutting tools, using wrenches.

07

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

08

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

09

Observe drilling or boring machine operations to detect any problems.

10

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