1 COMPETENCY ANALYSIS PROFILE GENERAL MACHINIST 429A (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 Wear, adjust, and maintain respiratory protectors. Practise safe work habits. Follow fire procedures Operate emergency safety Practise industrial hygiene housekeeping in the workplace Conduct preoperational check of Report injuries Follow procedures for applying first aid Lock out mechanical Handle designated substances Operate lifting

2 PLAN AND PREPARE FOR MACHINING JOB Read and interpret engineering drawings. Perform calculations for machining operations. Read and interpret workprocess Verify workpiece material. select cutting fluids select machines check machine controls and systems select tooling prepare cutting tools. 5231,05 select measuring instruments and checking devices Select machine speeds and feeds Lay out features of engineering drawings select workholding devices Pick up datum/starting select lifting and rigging Communicate with co-workers WORK-IN- PROCESS DIMENSIONAL OR SURFACE VERIFICATION Check straight cuts. Check shapes. Check threads. Check holes. Check tapers Check hardness Deburr Check surfaces

3 BENCHWORK Hand-file. Hand-saw. Hand-drill holes. Hand-tap threaded holes. Hand-ream Chase threads Hand-grind 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 Move workpiece

4 DRILLING USING DRILL PRESS/ MACHINE Select drill tooling. prepare cutting tools for drills. workpiece in drill. Set up tooling in drills. feeds of drill Centre-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 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 housekeeping

5 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 part-off Deburr

6 MILLING Select milling prepare milling Set-up and maintain milling adjustable support tools. Set-up milling feeds of mill Perform flycutting Face-mill Machine steps, cut-outs, angles, and open slots Machine a pocket or slots Machine a hole Bore holes Deburr

7 NC/CNC MACHINING select numerically controlled machining process. Prepare NC/CNC set-up sheet. Input and process program data to machine memory. Determine tool path and calculate coordinates. Identify, select, and set up NC/CNC cutting tools and tooling Set up NC/CNC Identify, select, and set machine parameters. Position and align workpiece in NC/CNC machine. Input and verify part program at NC/CNC machine controls. Store and record verified program Monitor NC/CNC machining process. Verify tool sequence, tool path, and collision avoidance program. Make adjustments to tooling and offsets
