They load them into the turret or carousel and set tool height, length, and diameter offsets Finding and setting the part home/origin (X, Y, Z axes) using edge finders, indicators, or machine probes Be able to complete in-process inspections in open setup (mics, calipers, thread measurements) and optical comparator (angles and overlays) Running "dry runs" (air cuts) or single-block executions on new setups to ensure there are no machine crashes or tool interference Making minor edits to G-code/M-code at the controller (such as adjusting feed rates, speeds, or depth of cut) to optimize the machining process or compensate for material hardness Monitoring tool wear and making precise wear offset adjustments to keep parts within blueprint tolerances as tools degrade Reading and interpreting complex geometric dimensioning and tolerancing (GD&T) symbols Using advanced precision measuring tools-including micrometers (inside, outside, depth), vernier calipers, bore gauges, thread plug gauges, and shadowgraphs-to inspect parts during production runs Machining the first part of a batch to perfection before switching the machine into full production mode Identifying the root cause of machining issues, such as poor surface finish, chatter, dimensional drift, or premature tool chipping Performing daily preventative maintenance on the machine, including checking oil levels, monitoring coolant concentration, and cleaning chips from critical way-covers Basic computer skills to enter inspection data, JobBOSS, etc. This includes mounting workholding devices like chucks, jaws, and collets (for lathes) or vises and fixtures (for mills) Selecting the correct cutting tools (inserts, drills, end mills, boring bars).
