Tasks
There are many tasks done by toolmakers and engineering patternmakers. A few are listed below:
- studying drawings and specifications to determine dimensions and tolerances of articles to be manufactured and models to be constructed
- measuring and marking out metal stock and castings using various gauges
- shaping metal and wood stock using machine tools
- checking accuracy of manufactured articles and finished patterns to fine tolerances, using precision measuring instruments
- testing and modifying manufactured articles
- applying protective finishes to patterns and painting pattern sections to indicate method of assembly
- assembling pattern sections and shaping work pieces to specified finish
- pouring and spreading materials into moulds and over models of patterns, and building laminations of fibreglass cloth and plastic resin to fabricate patterns
- repairing broken and damaged patterns and correcting patterns to compensate for defects in casting
- constructing templates for layout and inspection
