1 COMPETENCY ANALYSIS PROFILE Tool and Die Maker 430A (All unshaded skill sets must be demonstrated/completed) SKILL SETS SKILLS PROTECT SELF AND OTHERS Identify health and safety hazards. Wear, adjust, and maintain personal protective equipment. Wear, adjust, and maintain respiratory protectors. Practice safe work habits. Follow fire procedures Operate emergency safety equipment Practice industrial hygiene housekeeping in the workplace Conduct preoperational check of equipment Report injuries Follow procedures for applying first aid Lock out mechanical equipment for repair Handle designated substances Operate lifting equipment PLAN AND PREPARE FOR MACHINING JOB Read and interpret engineering drawings. Perform calculations for machining operations. Read and interpret workprocess Verify workpiece material. cutting fluids machines check machine controls and systems select tooling prepare cutting tools measuring instruments and checking devices Select machine speeds and feeds Lay out features of engineering drawings select workholding devices Pick up datum/starting lifting and rigging equipment Communicate with co-workers

2 WORK-IN- PROCESS DIMENSIONAL OR SURFACE VERIFICATION Check straight cuts. Check shapes. Check threads. Check holes. Check tapers Check hardness Deburr Check surfaces BENCH WORK Hand-file. Hand-saw. Hand-drill holes. Hand-tap threaded holes. Hand-ream Chase threads Hand-grind

3 SAWING Check fused/welded blade. Lay out features of engineering drawings. workpiece in saw. feeds of saw. Install and test-run blade Check first cut-off Cut shapes using a vertical bandsaw Cut squared and angled surfaces using a power cut-off saw Deburr DRILLING USING DRILL PRESS/ MACHINE Select drill tooling. prepare cutting tools for drills. workpiece in drill. Set up tooling in drills. feeds of drill Center-drill a layout punch mark Drill a hole Chamfer a hole Ream a hole Machine-thread a hole Spot-face a hole Counter-bore a hole Counter-sink a hole Deburr

4 MACHINE GRINDING Select grinding wheel. Check condition of grinding wheel. Install grinding wheel. workpiece in grinder. Surface grind Hone holes Lap workpiece Grind inside and outside diameters. (ID/OD) Grind tools and cutters Check ground surfaces LATHE WORK Select lathe cutting tools. prepare lathe workpiece in lathe. Set up lathe feeds of lathe Take a sizing (preliminary) cut Establish a reference or starting point (datum) Face a surface Turn an external diameter Drill a hole Bore an internal diameter Ream a hole Tap a hole Turn an internal or external thread Produce a taper Knurl cylindrical surface patterns Groove and partoff Deburr housekeeping

5 MILLING Select milling prepare milling Set-up and maintain milling adjustable support tools. Set-up milling feeds of mill Perform fly-cutting. Face-mill Machine steps, cut-outs, angles, and open slots Machine a pocket or slot Machine a hole Bore holes Deburr NC/CNC COMPUTERIZED CONTROLLED MACHINING numerically controlled machining process and set up NC/CNC cutting tools and tool holders. and set machine parameters. Position, align, & secure workpiece in NC/CNC machine. Input and verify part program to NC/CNC machine controls Monitor NC/CNC machining process. Verify tool sequence, tool path, and collision avoidance program. Make adjustments to tooling and offsets
