JOB ELEMENTS: Your qualifications will be evaluated on the basis of your level of knowledge skills abilities and/or competencies in the following areas:

l. Knowledge of technical practices in order to plan layout modify and/or manufacture a variety of unique prototype models. Knowledge in using ferrous and nonferrous metals and metal alloys to make complete models and model parts and the effect and relationship of heat treating annealing plating welding and other related work processes on machining operations in completing assignments. Knowledge to device and make special tools templates molds jigs gages fixtures and securing devices needed in fabrication or assembly of models. Knowledge of geometry trigonometry algebra and shop mathematics to calculate the sizes and dimensional relationships of parts working tolerances and clearances and machine tool settings.

2. Skill in using conventional machine tools and their attachments to perform machining processes requiring special adaptation of the equipment or process for which they were not specifically designed; and in using special or improvised tools fixtures and setups to machine surfaces configurations such as curved surfaces requiring machine feeds in different planes simultaneously surfaces having closely interrelated dimensions or surfaces having unusual or compound angular relationships. Skill in operating CNC machine tools through one complete cycle-to manufacture the first part; proof dimensions; check sufficiency of programming tooling fixturing and machine operations edit programs and make the normal changes required; and recommend changes to programs on deficiencies noted.

3. Skill in using a variety of specialized and precision-measuring instruments such micrometers vernier calipers height limit and surface gages and master gage blocks. Skill in interpreting blueprints program readouts and technical directives the use of shop mathematics and shop floor programming. Ability to test calibrate troubleshoot overhaul repair and install equipment to complete modeling projects.

4. Ability to use a very high degree of manual dexterity and work within extremely close tolerances. Ability to apply shop policies and procedures. Ability to communicate effectively both orally and in writing.

5. Knowledge of a variety of manufacturing processes and methods used during the planning stages of a project. Knowledge of how to plan and layout complete models assemblies and subassemblies to reproduce scale designs and to plan work requirements so that other employees assigned to the project can easily follow instructions. Knowledge of how to develop and fabricate special tools fixtures and jigs to hold machine fabricate and assemble items with compound curves and intersecting compound angles.

6. Skill in using tools such as soldering irons welding equipment bonding and brazing equipment and the full variety of metal working machines including the latest machines such as numerically controlled and electrical discharges machines. Skill in a variety of trade functions and able to fabricate assemble and align parts and components with critical centerline dimensions.
