Purpose
To prepare patterns for assembly and to prepare soluble cores for pattern molding; wax welds multiple components using fixtures to maintain dimensional conformity; repairs wax patterns and soluble cores in accordance with quality standards.
Essential Job Functions
* Pattern Finishing. Objective: to assemble pattern components and/or make dimensional alterations to patterns. Typical Activities:
o Reads techcards and engineering instructions.
o Assembles wax components into visually and dimensionally acceptable patterns; may use specialized fixturing.
o Modifies patterns or soluble cores using various hand tools and wax materials.
o Inspects modifications with special gauges and other measuring devises.
o Occasionally inserts ceramic cores in wax patterns and maintains dimensional integrity (TBO only).
* Repair/Restoration Objective: to fix broken or damaged patterns and soluble cores and restore to dimensionally acceptable condition. Typical Activities:
o Replaces broken features by wax welding fragments or by using other wax supplies to reconstruct missing areas.
o Fills voids and reforms damaged contours by attaching and shaping stock wax.
* Cleaning Objective: to work patterns and soluable core surfaces to meet visual inspection criteria. Typical Activities:
o Removes flash, mismatch and other surface positives using a variety of hand tools and materials.
o Fills or patches negatives using paint wax, melted stock wax, hot pencils and other tools and materials.
o Completes dimensional integrity restoration and plugging of holes per techcards.
o Inspects work for compliance with quality standards.
* Serialization Objective: to identify patterns with specified serial pads and numbers. Typical Activities:
o Places sticky wax pads or stamps specified serial numbers directly into patterns, per techcards.
* Safety Objective: to take responsibility for and demonstrate safe work practices. Typical Activities:
o Adheres to plant and department safety rules.
o Safely operates all equipment and tools.
o Identifies and reports safety problems.
