DIRECTION OF OTHERS: Direct Crane Operator/Slinger personnel in positioning workpiece and removing from machine.
WORKING PROCEDURE:
THE FOLLOWING ARE THE USUAL MAJOR JOB DUTIES BUT THIS DESCRIPTION DOES NOT PRECLUDE THE PERFORMANCE OF OTHER DUTIES BY THE INCUMBENT, NOR THE QUESTION BEING RAISED ON THE PROPER RATE FOR THE ASSIGNMENT.
1. Receive work assignments from lead or supervision.
2. Read and follow safety regulations and procedures, and MI package, including drawings, change notices, operation sheets, specifications, work authorizations, programs, readout sheets, and set-up sheets.
3. Select, align and position tools in holders to exacting tolerances. Select and set optimum speeds and feeds and tool travel stops. Set read out and positioning indicators for reference.
4. Analyze manufacturing information, production drawings, instructions, and parts. Check material size to verify there is sufficient material to machine to drawing. Select method of holding and aligning workpiece, and machining cuts required to obtain speed finishes and tolerances where details are not normally provided
5. 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.
6. Position, align, level and clamp various sizes and shapes of workpieces to machine and/or to positioning and supporting fixtures to exacting tolerances in all axis without distorting or stressing workpiece.
7. Setup, operate/perform and adjust any seven of the following types of manual and CNC/DNC machines and machine operations;
9. Disassemble setups of jobs and clean and return fixtures, gages, tools, etc, to their assigned locations.
10. Check work for conformance to specifications and chart dimensions. Sign off operations completed and obtain first piece and final inspection sign offs on operation sheets.
11. Must be able to obtain and maintain certified operator measurement certification through periodic testing.
12. Maintain tools, equipment, and work area in a clean and orderly condition.
13. Maintain a working knowledge of various machining principles and practices, processes, capabilities, tooling, and technologies. Recommend and/or initiate changes in machining procedures and methods to improve operating efficiency.
14. Relay pertinent job information to employees assigned to the same machines on follow up shifts.
15. Perform work of equal or lower classification as required.
