Experience Level(s):
Junior ⋅ Mid Level ⋅ Senior
Field(s):
Mechanical Engineering
PRIMARY FUNCTION:
Analyze data and plan sequence of operations and set up and perform a variety of machining operations on a limited number of large manual and CNC/DNC vertical and horizontal milling, drilling, broaching, boring, and turning machines. Machine parts with numerous steps, diameters, and fits to exacting tolerances of finish, perpendicularity, concentricity, parallelism where details are not normally provided.
TOOLS AND EQUIPMENT:
Manual and CNC/DNC horizontal/vertical milling, boring, drilling, broaching, and turning machines, layout machine and table, tracer attachments, indexing tables, shims, nuts, bolts, clamps, chuck jaws, fixtures, jigs, vises, tool holders, end mills, face mills, drills, taps, reamers, boring bars, carbide tools, high speed tools, broaches, templates: scribes, hammers, wrenches, height gages, gage blocks, tape punches, micro‑cassette recorders, cranes, rigging, etc. Electronic/manual measuring equipment including scopes, levels, indicators, verniers, squares, micrometers, gages and chart recorders.
MATERIAL:
Carbon and stainless steel, alloy steel, aluminum, brass, bronze, rough and semi‑finished stock, castings, forgings, fabrications, cutting oil, coolant, hydraulic fluid, etc.
DIRECTION OF OTHERS:
Direct Crane Operator/Slinger personnel in positioning workpiece and removing from machine.
WORKING PROCEDURE:
1. Align, shim, and position tools in holders to exacting tolerances. Select and set optimum speeds and feeds. Set read out and positioning indicators for reference.
2. Analyze manufacturing information, production drawings, instructions, and parts. Plan sequence of operations, method of holding and aligning workpiece, and machining cuts required to obtain specified finishes and tolerances where details are not normally provided.
3. Lay out and scribe or mark on parts reference lines and center points for precise machining dimensions where accuracy is essential. Use trigonometry and geometry tables and/or charts to determine dimensions for bolt circles, angles, chords, etc.
4. Position, align, level and clamp workpieces and/or fixtures to exacting tolerances in all axis. Improvise as necessary to prevent distortion in positioning and holding part.
5. Set up, operate/perform and adjust any (8) of the following types of machines/machining operations Manual: 1) Boring Mill‑Horiz, 2) Boring Mill‑Vert, 3) Lathe‑Horiz, 4) Planer Mill, 5) Line Boring, 6) Drilling, 7) Superfinishing, 8) Layout, 9) Broaching (multiple or single task), 10) Grinding. CNC,/DNC: 1) Boring Mill‑Horiz, 2) Boring Mill‑Vert, 3) Lathe‑Horiz, 4) Drilling, to machine a variety of parts with numerous steps, diameters and fits to accomplish exacting tolerances of finish, perpendicularity, concentricity, parallelism and flatness, etc.
6. Develop and/or follow the sequencing of CNC/DNC machines. Prepare, proof or make changes to programs as necessary to produce part to specifications. Correct program errors and supplement movement in manual mode and perform operations.
